Abstract and Figures

Additional Middle Paleolithic human remains from layers 17, 18, and 22 of the Gruta da Oliveira, Portugal consist of a proximal manual phalanx 2 (Oliveira 5), a partial postcanine tooth (Oliveira 6), a humeral diaphysis (Oliveira 7), a distal mandibular molar (Oliveira 8), and a mandibular premolar (P(3) ) (Oliveira 9). Oliveira 5, 6, and 8 are unremarkable for Late Pleistocene humans. The Oliveira 7 right humerus is moderately robust or the individual had the stocky body proportions of other European (including Iberian) Neandertals. The Oliveira 9 P(3) has a large and symmetrical crown and lacks a distal accessory ridge and accessory lingual cusps, overlapping both Neandertal and recent human ranges of variation. It contrasts with at least recent human P(3) s in having relatively thin enamel. These join the Oliveira 1 to 4 remains in further documenting early MIS 3 Neandertal morphology in western Iberia.

ABSTRACT Additional Middle Paleolithic human
remains from layers 17, 18, and 22 of the Gruta da Oli-
veira, Portugal consist of a proximal manual phalanx 2
(Oliveira 5), a partial postcanine tooth (Oliveira 6), a
humeral diaphysis (Oliveira 7), a distal mandibular molar
(Oliveira 8), and a mandibular premolar (P
3
) (Oliveira 9).
Oliveira 5, 6, and 8 are unremarkable for Late Pleisto-
cene humans. The Oliveira 7 right humerus is moderately
robust or the individual had the stocky body proportions
of other European (including Iberian) Neandertals. The
Oliveira 9 P
3
has a large and symmetrical crown and
lacks a distal accessory ridge and accessory lingual cusps,
overlapping both Neandertal and recent human ranges of
variation. It contrasts with at least recent human P
3
sin
having relatively thin enamel. These join the Oliveira
1 to 4 remains in further documenting early MIS 3
Neandertal morphology in western Iberia. Am J Phys

Until recently. Iberia contributed relatively little to
Neandertal paleontology (Garralda, 2006). However, a
series of discoveries has greatly increased the Iberian
Neandertal presence (Quam et al., 2001; Lorenzo and
Montes, 2001; Arsuaga et al., 2001b, 2007; Barroso-Ruı
´z
et al., 2003; Daura et al., 2005, Rosas et al., 2006; Sar-
rio
´n, 2006; Trinkaus et al., 2007; Walker et al., 2008,
2012), confirmed their late presence south of the Pyre-
nees (Walker et al., 2008; cf., Hublin et al., 1995), docu-
mented aspects of their paleobiology (Lalueza et al.,
1993; Arsuaga et al., 2001a; Rosas et al., 2006; Walker et
al., 2011b,c; Estalrrich et al., 2011), and raised issues
regarding Neandertal variability (Rosas et al., 2006;
Walker et al., 2008, 2011b; Alca
´zar de Velasco et al.,
2011).
In this context, we present additional Middle Paleo-
lithic human remains from the Gruta da Oliveira, Torres
Novas, Estremadura, Portugal. Previously described
human specimens from Oliveira (Trinkaus et al., 2007)
confirmed that these remains derived from Neandertals,
especially Oliveira 1 and 3. The additional remains come
from deposits of the same or similar age and contribute
to both Neandertal paleobiology and variability within
Iberia.
THE GRUTA DA OLIVEIRA
The Gruta da Oliveira (39830@23@N, 8836049@W) is
a collapsed entrance of the multilevel karstic system
associated with the spring of a tributary of the Tagus,
the Almonda River, located 100 km NE of Lisbon. Dis-
covered in 1989, the site contains a Middle Paleolithic
sequence excavated over a thickness of 7 m (Fig. 1).
Extensive, updated discussions of the stratigraphy and
dating are in Angelucci and Zilha
˜o (2009), Zilha
˜o et al.
(2010), and Hoffmann et al. (in press). As of 2011, our
understanding of the site’s formation can be summarized
as follows.
The baseline for the accumulation of the deposits is a
stalagmitic crust for which a terminus post quem of
107 ka is provided by the U-Th age of a candlestick
stalagmite growing on top of it in the Crivo area of this
level of the karstic system. Above, there are 3mof
deposits, the surface of which is exposed in the Cone
Moustierense, the first discovered area of the site, from
the bottom, via speleo-archeological exploration of the
inner karst passages. A Uranium series age of 62.5 ka
was obtained on horse (Equus caballus) tooth enamel
from a sample retrieved therein in 1990, under Early
Uptake assumptions (Zilha
˜o and Mckinney, 1995); the
date is the average of two measurements on the same
sample: 70,250 69,000 and 53,000 15,600/25,300 (1 r
errors). The surface of the Cone Moustierense corre-
sponds to the interface between layers 25 and 26 of the
stratigraphic succession that has been undergoing top–
down archeological excavation since the collapsed en-
trance was opened in 1991. This succession can be subdi-
vided in five main blocks (Fig. 1), from the bottom up:

layers 23–25 are roof collapse and associated sedi-
ment fill, with a low density of artifacts and faunal
remains scattered in homogeneously over a thick-
ness of 1.5 m;
layers 20–22, a 65-cm thick block of sandy, cave
earth sediments, formed during a period of relative
structural stabilization of the roof and walls of the
cave, allowing its use for habitation, as documented
by a large hearth, 1.5 m in diameter, whose con-
tents and associated spatial scatter are layer 21;
layers 15–19, a 1.3-m thick block of deposits formed dur-
ing a period of destabilization that saw multiton bould-
ers collapse over the surfaces of layers 20, 19, and 15; at
this time, human occupation took place in the extant
cave porch (the ‘‘Exterior’’), with run-off and slope proc-
esses leading to syn- or post-depositional, short-distance
displacement of finds towards the excavated area;
layers 9–14 accumulated in the depression formed
inward of the huge boulder fallen over the surface of
layer 15 in grid units N-R/12–15, with human occu-
pation taking place in the ‘‘Side Passage’’ and the
‘‘27-S Chamber’’, as documented by a hearth in grid
units L20–21, layer 14, and the associated dense
concentration of lithics, fauna, charcoal, and burnt
bone;
layers 7–8 formed on top of and outward from the N-
R/12–15 boulder, with a tail extending into the inner
areas, which by layer 9 times had become almost
filled-up; layer 8 corresponds to the latest human
occupation of the site, while layer 7, archeologically
sterile, contains faunal remains probably accumu-
lated by carnivores and is capped by flowstone, in
turn buried under a thick colmatation breccia.
Radiocarbon dates on burnt bone, plus U-series results
on layer 8 bone samples, place layers 7–8 37 ka cal BP,
and layers 9–14 beyond 43.5 ka cal BP. The remains
described here come from deeper in the stratigraphy,
within early marine isotope stage (MIS) 3. The Oliveira

5 phalanx and Oliveira 6 tooth were found at the inter-
face between layers 17 and 18, and the Oliveira 7 hu-
merus was in the upper part of layer 18, 11 cm away
from and 7 cm below the previously described Oliveira 3
humerus from layer 18. Oliveira 8 and 9 were recovered
25 cm from each other in layer 22, the latter 9 cm
above the former [i.e., given the dip of the deposit and
the approximate positioning of Oliveira 8 (see below), at
about the same elevation].
MATERIALS AND METHODS
This article is a presentation of newly excavated Late
Pleistocene human remains, and as such it describes
them in the context of relevant comparative samples.
They are compared to three samples, Late Pleistocene
(MIS 5 to 3) western Eurasian late archaic humans
(Neandertals), southwest Asian early Late Pleistocene
(MIS 5c) middle Paleolithic modern humans (MPMH),
and Eurasian and North African Interpleniglacial (MIS
3) Early and Mid Upper Paleolithic modern humans
(EUP/MUP). The one exception to this is the dental dis-
crete trait frequencies. Most of those data come from
Bailey (2006), and include a few southern African MSA
(MIS 5–4) late archaic humans (which some consider to
be early modern humans) with the MPMH; also, the
upper Paleolithic sample includes both MIS 3 and 2
specimens. As with the southwest Asian MPMH, the
African MSA teeth appear to mostly retain plesiomor-
phic traits and therefore should not bias the compari-
sons. The MIS 2 teeth are notable mostly for reductions
in molar cusp numbers, in the direction of recent
humans. Comparative data for P
3
dental tissue propor-
tions are principally from recent humans, plus data for
two Neandertals.
The linear measurements follow the Martin system
(M-#) (Bra
¨uer, 1988), supplemented as needed. Dental
discrete traits follow the ASUDAS system (Scott and
Turner, 1997) as modified and expanded for later Pleisto-
cene humans by Bailey (2002, 2006). Occlusal wear
scores follow Molnar (1971) and Smith (1984).
The Oliveira 7 distal humeral diaphysis was scanned
on a Siemens Somatom Definition CT Scanner at the
Washington University School of Medicine (kVp: 120;
effective mass: 400 mA 3s; rotation time: 1; pitch: 0.7;
columnation: 16 30.3 mm; slice thickness: 400 lm;
reconstruction increment: 100 lm), producing 1,291 sli-
ces. Geometric cross-sectional parameters (areas and sec-
ond moments of area) were computed from the slice at
35% of length using SLICE/SLCOMM (Nagurka and
Hayes, 1980; Eschman, 1992) after visual reconstruction
of missing medial diaphyseal bone (see below).
The Oliveira 9 P
3
was micro-CT scanned using a
Scanco VivaCT 40 scanner at the Washington University
School of Medicine (70 kVp; 114 lA; 500 projections).
The final volume was reconstructed with an isotropic
voxel size of 21 lm. A buccolingual section was virtually
produced through the P
3
(visually reconstructing the
worn cusp tip) using Amira 5.2.2 software (Visage Imag-
ing) and following the method described by Feeney et al.
(2010) (Fig. 9). Physically and virtually produced sec-
tions closely approximate one another (Olejniczak and
Grine, 2006), and therefore recent human comparative
data were tabulated from both physical (Saunders et al.,
2007; Smith et al., 2008) and virtually generated
(Feeney et al., 2010; Smith et al., 2012) sections. The re-
sultant measurements (Table 6) follow Martin (1985)
and were derived from the section using MPSAK 2.9
software (Dean and Wood, 2003).
Comparisons are made principally using the standar-
dized linear residuals (raw residual/standard deviation
of the pooled residuals) from the reduced major axis
(RMA) regression line through the pooled comparative
sample trimmed of outliers. Significance is based on non-
parametric (Kruskal-Wallis) assessments [computed
using NCSS 7.1 (Hintze, 2010)]. Summary statistics are
nonetheless provided as: mean 6SD (N). Exact chi-
square P-values for the comparative discrete trait distri-
butions were computed with Stat-Xact 4.0 (Mehta and
Patel, 1999). Within sets of comparisons, P-values are
evaluated using a sequentially reductive multiple com-
parison correction, following Rice (1989) and Proschan
and Waclawiw (2000).
Oliveira 5—Proximal manual phalanx
Preservation and identification. The partial proximal
diaphysis and base of a human right second manual
proximal phalanx (Olv P15-478) was discovered during
excavation on July 3, 2008 at the base of layer 17 (Fig.
2). The base is complete with minor surface abrasion to
the dorsal margin of the metacarpal facet but primarily
to the dorsal capsular attachment area. From the intact
subchondral bone margins radially and ulnarly, it does
not appear that more than a couple of tenths of a milli-
meter of the dorsal articular facet were lost. The capsu-
lar insertion area has lost 0.5–1.0 mm of bone. The dor-
sal diaphysis extends distally for 18.9 mm from the mid-
dorsal articular facet, but the palmar extent is only 10.7
mm from the palmar middle of the facet. There are thin
irregular concretions on the metacarpal facet and
between the proximal palmar tubercles for the metacar-
pophalangeal collateral ligaments, but neither of them
obscures morphology nor affects measurements. The
maximum preserved length is 20.9 mm.

The bone is identified as a manual proximal phalanx
given its evenly concave articular facet, size and the
larger radioulnar than dorsopalmar dimensions of the
proximal facet and epiphysis. It is from the right second
ray given the modest interosseus tubercle on the right
base (when viewed dorsoproximally) and the prominent
one on the left base. The radial versus ulnar tubercle dif-
ferential is greater than seen on third proximal pha-
langes.
There is no evidence of the proximal epiphyseal fusion
line and, therefore, the bone derives from an individual
minimally in the second half of the second decade post-
natal and probably fully mature (Greulich and Pyle,
1971). There are no pathological lesions.
Morphology. The metacarpal facet is transversely ovoid
with a concavity that is principally radioulnar. The max-
imum depth of the concavity, from the tangent to its ra-
dial and ulnar margins, is 1.4 mm. The ulnar base is
minimally expanded for the capsular attachment and
the associated tendon for the second palmar interosseus
muscle. The radial side has a large and prominent swel-
ling for the insertion of the tendon of the first dorsal
interosseus muscle, evident especially dorsoradially. The
preserved portion of the diaphysis has dorsally thin cort-
ical bone, 1.2 mm thick at the most distally preserved
mid-dorsal margin.
The Oliveira 5 phalangeal base is average to moder-
ately small (Table 1). The one comparison which has the
potential to provide paleobiological information, between
the maximum and articular breadths (Fig. 3), should
reflect the hypertrophy of the insertion for the first dor-
sal interosseus, assuming that articular breadth is an in-
dependent variable related to body size. There is no dif-
ference between the Neandertals and the EUP/MUP
remains in this comparison. The MPMH (all from Qaf-
zeh) have relatively larger maximum breadths, espe-
cially Qafzeh 3. The comparative samples are different
at P50.010, driven by the high values for the MPMH
sample (Neandertal – EUP/MUP Wilcoxon P50.649). It
is unclear why the MPMH sample should be largely sep-
arate from the others, given the generally (but not uni-
versally) reduced hypertrophy of their hands relative to
the Neandertals (Niewoehner, 2001; Maki and Trinkaus,
2011).
In this comparison, Oliveira 5 falls along the higher
margin of the Neandertal—EUP/MUP distribution,
emphasizing its moderately large first dorsal interosseus
tubercle, most similar to the Qafzeh specimens. Its
residual value of 1.23 is above all of the other Late Pleis-
tocene specimens except Qafzeh 3 and 7.
Oliveira 6—Postcanine tooth fragment
Preservation and identification. Oliveira 6 (Olv P16-
812) is a fragment of a heavily worn permanent premo-
lar or molar, discovered on July 3, 2008 at the base of
layer 17 (Fig. 4). The tooth retains 6.5 mm of the side of
the crown and exposed dentine extending up to 4.1 mm
from the external enamel. At its most complete margin,
the crown height is 2.9 mm. There is 10.8 mm of a
crushed partial root encrusted in matrix. There is no oc-
clusal enamel, only the remains of a worn dentine basin
(probably Smith wear Stage 7 and Molnar wear Stage
6).
The retained enamel has no hypoplasias or other path-
ological lesions. There is, however, a rectangular chip of
enamel missing from the middle of the preserved occlu-
sal margin, 1.8 mm wide and extending 0.8 mm from the
occlusal margin (Fig. 4). The margins are rounded, espe-
cially on the right side (with the occlusal surface up) and
the internal margin towards the dentine. The chip was
therefore lost antemortem, with subsequent attrition in
the margins. It does not have the hollowed out and
etched form of a carious lesion. It appears to be an ante-
mortem traumatic chipping of the enamel border that
occurred after it was weakened by wear. Similar enamel
chipping is evident on other Late Pleistocene teeth (e.g.,
Frayer and Russell, 1987; Mallegni, 1995; Hillson, 2006;
Doboset al., 2010). The tooth provides little other pale-
ontological information.

Oliveira 7—Distal humeral diaphysis
Preservation. The Oliveira 7 humerus (Olv O16-422)
was discovered during excavation on July 12, 2008 in
the upper portion of layer 18. It is a distal diaphysis
from the distal end of the deltoid tuberosity anteriorly to
proximal olecranon fossa (Fig. 5). The diaphysis was
cleaned extensively with a 5.0% and then 7.5% solution
of acetic acid, which removed little of the red-brown car-
bonate encrustation that covers principally the antero-
medial surface; given that the encrustation is thin and
hides little morphology, further efforts to chemically or
mechanically clean the bone were deemed inadvisable.
There are no age indicators preserved on the specimen,
but its overall size and morphology imply full maturity.
There are no pathological lesions. Its maximum pre-
served length is 129 mm.
The humerus has a 1–2 mm wide longitudinal crack
from the proximal end of the lateral pillar posteriorly to
the posterolateral edge towards midshaft; it is 70 mm
long. There is a larger gap along the medial side of the
medial supracondylar area, 3.5 mm wide, which then
rotates to the posteromedial margin as it goes proximally
up to the posterior proximal break. Despite the size of
this medial-posteromedial opening, the CT images con-
firm that there was no expansion of the diaphysis along
that region, only a loss of bone with variable matrix
infilling (Fig. 5).
Proximally the bone has an irregular break trans-
versely across the diaphysis on the anterior three-quar-
ters of the bone. Posteriorly, there is a piece 22 mm
long and 17 mm wide missing, distally to the postero-
medial gap. The anterolateral margin of the bone at the
break has the distal deltoid tuberosity, extending 10
mm from the proximoanterior break. The proximal break
is therefore close to midshaft. Distally, there is the be-
ginning of the midline depression for the olecranon fossa,
but it does not extend to the capsular attachment line.
The medial side is broken off at the proximal end of the
olecranon fossa, but the lateral side extends slightly fur-
ther and retains most of the lateral supracondylar crest.
The edges proximally and distally exhibit the angular
breaks of dry bone, similar to the Oliveira 3 distal hu-
merus and distinct from the rounded margins of the
gnawed Oliveira 4 tibial diaphysis. There is no carnivore
damage to the bone. Linear measurements and mid-
distal cross-sectional geometric parameters are in Table 2.
Overall size. The bone preserves the distal deltoid tu-
berosity and the proximal olecranon fossa, which enable
estimation of its original anatomical lengths; the dis-
tance between them is 105 mm (61–2 mm, depending
on interpretation of the distal deltoid tuberosity margin).
This distance is moderately well correlated with articu-
lar length in a pooled sample of recent humans (N540)
plus six Late Pleistocene humeri (five Neandertals plus
Skhul 4) (ArtLen 51.715 3OlvLen 1128; r
2
50.614).
The resultant estimate for Oliveira 7 (308 613 mm) has
a large SE
est
(4.6%) and 95% CI (282–334 mm). The
same sample predicts a maximum length of 315 613
mm (95% CI; 288–342 mm) for Oliveira 7 (MaxLen 5
1.749 3OlvLen 1132; r
2
50.613). Scaling of the dia-
physeal rigidity (Fig. 6A) suggests that the true value of
its length lies within the upper half of the 95% CI,
unless it was exceptionally robust.
The maximum length mean estimate is above the over-
all mean of a Neandertal sample (Table 3); it is within
the male range (305–337 mm, N56) and well above
that of the females (272–286 mm). It is also below the
means of the MPMH and EUP/MUP samples. Yet, the
95% CI for Oliveira 7 encompasses half of the MPMH
values, 71.4% of the EUP/MUP ones, and all of the
Neandertal values except for the three females.

Morphology.
Surficial morphology. Oliveira 7 presents little surface
morphology of note. The lateral supracondylar crest is
distinct and extends 1.5 mm from the distal break to
the level of the minimum diaphyseal circumference. The
distal deltoid tuberosity is moderately rugose but proj-
ects minimally from the diaphyseal contour. At the prox-
imal break, it is 9.7 mm wide, suggesting an original
maximum breadth of 10–12 mm. The distal end is insuf-
ficiently preserved to assess the pillar thicknesses or
whether it had a septal aperture.
Diaphyseal hypertrophy. The distal minimum circumfer-
ence of 68 mm is modestly above the means of the com-
parative samples (Table 3). A mean robusticity index
using distal circumference and maximum length (21.6) is
within the Neandertal range (18.7 – 23.9) but outside
the ranges of variation of the early modern human sam-
ples (MPMH max: 19.7; EUP/MUP max: 20.6). Using the
minimum 95% CI value (19.9) for Oliveira 7 places it at
the top of the early modern human variation.
The midshaft does not provide a full cross-section, but
the mid-distal (35%) cross-section is largely present (Fig.

5). It has been possible to visually reconstruct the miss-
ing portions from the CT slice (slice 935) located at 35%
of the predicted articular length, filling in the posterome-
dial and posterolateral bone following the preserved con-
tours. The endosteal contour was visually separated
from the matrix in-filling.
A comparison of the 35% polar moment of area (as an
overall reflection of diaphyseal rigidity) to humeral
length (Fig. 6A) places the mean value for Oliveira 7
among the more robust of the Neandertal humeri, with a
significant difference across the comparative samples (P
50.007). With a standardized residual of 1.52 for Oli-
veira 7, only Shanidar 4 provides a relatively higher
value (2.07), but other specimens (especially La Chap-
elle-aux-Saints 1 and Kebara 2 at 1.33) are close. Its
mean estimate is well above those of the early modern
humans, although it is close to the [possibly pathologi-
cally elevated (Crevecoeur, 2008)] value (1.04) for Nazlet
Khater 2. The longer length from its 95% CI places it
among the stronger of the early modern humans, but the
shorter length limit would make it exceptionally robust
(standardized residual of 2.74).
These two reflections of humeral diaphyseal robust-
ness can reflect either generalized humeral diaphyseal
hypertrophy, in Oliveira 7 and the Neandertals in gen-
eral, or they may be largely due to the stockier body pro-
portions of the Neandertals relative to early modern
humans (Holliday, 1997). It is not possible to determine
the body proportions of Oliveira 7 (or the other Oliveira
Neandertals), but two more southern Iberian Neander-
tals, Palomas 96 and probably Palomas 92 (Walker et al.,
2011a,b), exhibit the ‘‘arctic’’ body proportions of more
northern European Neandertals. Among recent humans
(Ruff, 2000; Shackelford, 2005), consistent patterns of
robustness are achieved only if humeral diaphyseal
strength is scaled to bone length times body mass. Given
this, the comparisons of diaphyseal circumference or po-
lar moment of area to length alone can indicate strong
arms and/or ‘‘arctic’’ body proportions for Oliveira 7.
A further (partial) reflection of diaphyseal hypertrophy
is cortical area relative to subperiosteal area (Fig. 6B).
There is little difference across Late Pleistocene right
humeri (P50.196). Oliveira 7 falls along the upper mar-
gins of the distribution, close to the highest relative val-
ues for Neandertals and early modern humans; its
standardized residual of 1.31 is close to those of Dolnı
´
Ve
˘stonice 41 (1.31), Krapina 173 (1.24), Nahal ‘En-Gev 1
(1.28) and Regourdou 1 (1.44).
Diaphyseal shape. Diaphyseal shape can be assessed
using the perpendicular second moments of area at the
mid-distal diaphysis and external diameters near mid-
shaft. In the former, there is no difference across the
comparative samples (P50.965), and Oliveira 7 is in
the middle of the distribution (standardized residual:
20.04) (Fig. 6C). At midshaft, the Oliveira 7 minimum
breadth can be measured directly and the maximum di-
ameter can be estimated by extending the posterior bor-
der proximally. The resultant values (Table 2) place Oli-
veira 7 in the overlap of the Neandertal and the EUP/
MUP samples (Fig. 6D). The larger MPMH humeri fall
with the rounder Upper Paleolithic humeri, but the
smaller ones cluster with the Neandertals. As a result,
the three samples are significantly different (P50.016)
and the Neandertal and EUP/MUP ones are especially
contrasting despite some overlap (Wilcoxon P50.003).
Oliveira 7 has a positive standardized residual (0.43),
but one nonetheless exceeded by Mladec
ˇ24, Pavlov 1,
Pr
ˇedmostı
´4, the three smaller Skhul 2, 7 and 15, and
71.4% of the 14 Neandertals.
Oliveira 8—Lower molar
Preservation and identification. The Oliveira 8 tooth
(Olv N16-373) was found during excavation on July 1,
2010 in layer 22. It was encased in extremely hard brec-
cia removed during excavation with a Spit electro-pneu-
matic hammer; it was discovered as the tool flaked off
the brecciated deposit, exposing the sliced specimen. The
portions recovered include a partial crown from the oc-
clusal surface to the cervix and half of a root still
encased in the breccia (Fig. 7). The partial crown fits
cleanly onto the root with minor loss of cervical material.
The root is exposed internally; it was left in the matrix,
since it would be nearly impossible to extract it intact.
Extended search failed to locate the remainder of the
tooth; it probably shattered from the impact.
The tooth is a distal portion of a mandibular molar,
probably from the right side. There is a complete cusp
preserved, between portions of two other cusps. The
three cusps conform to the pattern seen in the distal por-
tions of lower molar crowns, in which the intact one is
the hypoconulid (cusp 5) and the two partially preserved
cusps would be the hypoconid (cusp 3) and the entoconid
(cusp 4). The sulci between the middle cusp and the
other two cusps converge in the buccolingual middle of
the occlusal surface, deviate slightly to the right and
then mesially. The exposed root has a single canal and
converges to a closed apex. It curves apically away from
the break relative to the occlusal plane, or distally for a
lower molar. It also curves slightly to the left when
viewed mesially.
Given the orientation of the root and the positions of
the cusps and sulci between them, the tooth is best con-
sidered as right, making the more intact of the two more
mesial cusps the hypoconid. The distal crown lacks an
interproximal wear facet. The occlusal cusps have only a
slight polishing of the enamel (Smith and Molnar wear
Stage 2), indicating that it is an M
3
or a more mesial
molar prior to the eruption of the next distal molar.
The root apex of the distal root is completely closed
[Moorrees et al. (1963) Ac], which indicates a median

age [9 years if an M
1
,[14 years if an M
2
, and [20
years if an M
3
, based on recent EuroAmerican standards
(Shackelford et al., 2012) despite indications of relatively
rapid M3 formation in Late Pleistocene humans (Tomp-
kins, 1996) [note that the absolute dental developmental
rates of Late Pleistocene humans are unknown (Gua-
telli-Steinberg, 2009) but are probably within the ranges
of variation of recent humans (Shackelford et al., 2012)].
The tooth is therefore a lower right molar of indeter-
minate number. Yet, it derives from the same excavation
layer as Oliveira 9, a lower right P
3
recovered nearby
(see below). It is possible that both teeth derive from the
same mandible, given their stratigraphic contemporane-
ity and their modest degrees of occlusal wear. The Oli-
veira 9 P
3
has more occlusal wear than Oliveira 8, as
well as distinct interproximal facets. It also had achieved
apex fusion stage either A
1/2
or A
c
, indicating an age-at-
death 12–13 years (see below). If the two teeth are
from one arcade, then it is unlikely that Oliveira 8 rep-
resents an M
1
and most likely it is an M
2
or M
3
, given
its minimal occlusal wear and no distal interproximal
facet.
In addition to the excavation damage, the crown lost a
chip of enamel during fossilization from the distolingual
corner, at the end of the sulcus between the entoconid
and the hypoconulid. There is a small hypoplastic pit on
the buccal face of the hypoconid, 4.4 mm from the cervix;
unworn buccal crown height on the hypoconid is 6.2 mm.
Around the distal crown, 2.0 mm from the cervix, there
is a shallow groove with traces of calculus. The groove
appears to be a mild linear dental enamel hypoplasia.
These hypoplasias join the relatively high frequencies of
such defects on the distal molars among the Neandertals
(Ogilvie et al., 1989).
Morphology. Oliveira 8 is unlikely to have had four
cusps, similar to almost all Late Pleistocene M
1
s and
M
2
s, all Neandertal M
3
s and 70% of early modern
human M
3
s (Table 4). If the three distal cusps are cor-
rectly identified, then it lacks a cusp 6 (stage 0); the
common configuration across Late Pleistocene samples.
Note that the only significant difference in these discrete
traits in the Late Pleistocene is in whether M
2
s and M
3
s
have only 4 cusps; if Oliveira 8 is an M
3
, its cusp num-
ber would align it more with the Neandertals.
The buccolingual breadth at the mesial break is 9.3
mm, and the original crown breadth is likely to have
been 10–11 mm. A crown diameter in that range is mod-
est but unexceptional for a Late Pleistocene lower molar
(Trinkaus, 2004).
Oliveira 9—Lower first premolar (P
3
)
Preservation and attrition. A lower first premolar
(P
3
) (Olv N15-383) was discovered on July 7, 2010 in the
hard breccia facies of layer 22 that had to be excavated
with power tools (see above) (Fig. 8). Its two pieces rejoin
without distortion at the cervix. The root apex is absent,
and the tapering suggests that 1–2 mm were lost. There
is also an area of the disto-occlusal quarter of the buccal
crown, 535mm
2
, where the enamel has been
slightly etched. The lingual half of the lingual cusp
(metaconid) is absent; it does not obscure the size of the
tubercle, but it necessitates minor estimation of the
crown buccolingual diameter and contour.
The occlusal surface of the protoconid has been planed
off through normal occlusal wear, resulting in exposure
of a central, 0.5 mm diameter, area of dentine (Smith
wear Stage 2b; Molnar wear Stage 3). There is a flat

American Journal of Physical Anthropology
mesial interproximal facet in the middle of the occlusal
half of the mesial crown, 3.2 mm high and 2.4 mm wide.
The middle of it still covers the dentine, to a minimum
enamel thickness of 0.7 mm. The mesial side has there-
fore been planed off substantially. Distally, there is a flat
interproximal facet 2.9 mm high and 4.1 mm wide. How-
ever, it is on the distolingual side of the crown, along the
distal marginal ridge. It does not go onto the mid-distal
extent of the tooth, such that there is no reduction in
the crown mesiodistal diameter from distal interproxi-
mal wear (only from mesial interproximal wear).
Although readily apparent in occlusal view, it did not
significantly change the crown contour of the tooth.
Given the normal mesial but lingually displaced distal
interproximal facets, there was some dental rotation. Ei-
ther the distal P
3
was buccally displaced relative to the
P
4
, or the mesial P
4
was lingually displaced. Given that
the mesial facet is in the normal position for the C
1
, the
latter scenario is probable. Rotated premolars are com-
mon among the Neandertals, being particularly frequent
in the Krapina sample; they are also present in both
Middle and Upper Paleolithic modern humans (Hillson,
2006; Rougier et al., 2006).
The damaged root apex indicates that it should have
been developmentally at least at A
1/2
and probably A
c
.
The former would provide a median age of 13 years,
and the latter would indicate an age [12 years, based
on recent EuroAmericans (Shackelford et al., 2012).
Morphology. Except for damage to the lingual metaco-
nid, the occlusal morphology of Oliveira 9 is intact. The
buccal surface is rounded with a bulge on the cervical
half and largely straight in mesial view on the occlusal
half. The protoconid appears to have had a slightly lon-
ger distal than mesial shoulder. There is a complete, if
concave, transverse crest from the protoconid to the
metaconid (Grade 1), but there is neither a mesial nor a
distal accessory ridge (Grade 0). There are well-formed
mesial and distal marginal ridges, but the mesial one is
traversed next to the metaconid by a distinct but small
mesial lingual groove (Grade 1). The metaconid is cen-
trally located on the lingual side (Grade 0), and there is
little asymmetry of the crown (Grade 0); the lingually
displaced distal interproximal facet has little effect on
the scoring of the crown as essentially symmetrical.
There are no accessory lingual cusps (Grade 1).
These discrete traits of the P
3
, taken individually,
place Oliveira 9 within the ranges of variation of the
Late Pleistocene samples (Table 5). It differs from the
Neandertals principally in its symmetry, the one feature
in which the samples are significantly different,
although there is considerable overlap across the sam-

ples. It should be noted that although Bailey (2006) and
the expanded data set in Table 5 score Neandertal P
3
s
as overwhelmingly ‘‘asymmetrical,’’ Martino
´n-Torres et
al. (2012) considered them to be only slightly asymmetri-
cal. Oliveira 9 also differs from most Neandertals in its
absence of accessory lingual cusps and especially a distal
accessory ridge.
It has been possible to reasonably visually reconstruct
the missing crown portions for a buccolingual slice
through the cusp tips (Fig. 9) and estimate enamel and
dentine areas (Table 6). Limited comparative Late Pleis-
tocene data for P
3
s are available, but more substantial
data exist for samples of recent humans. The Oliveira 9
coronal dentine area (including the pulp space) and
enamel-dentine junction length are similar to the larger
mean values for the recent human samples, but they are
modestly smaller than the mean of two other Neandertal
P
3
s. Yet, its enamel area is matched only by the mean of
the small EuroCanadian teeth, resulting in low average
(AET) and relative (RET) enamel thicknesses, even
below the mean of the two other Neandertal P
3
s. How-
ever, for the samples for which recent human distribu-
tions are available (Feeney et al., 2010; Smith et al.,
2012), the Oliveira 9 values are within their ranges of
variation. It is nonetheless likely that Oliveira 9 follows
the general Neandertal pattern of having low RET, at
least relative to recent humans (cf., Olejniczak et al.,
2008; Bayle et al., 2010; Crevecoeur et al., 2010; Smith
et al., 2012).
The Oliveira 9 root is moderately broad in its cervical
half, and then it tapers modestly to the apical break.
There is a single shallow and smooth longitudinal groove
on both its mesial and distal sides. There is no separa-
tion of the root into two (Grade 0 or 1), the common later
Pleistocene and recent human pattern (Martino
´n-Torres
et al., 2012).
The Oliveira 9 crown buccolingual breadth as pre-
served is 8.8 mm, but the damage to the metaconid
means that it was slightly larger. Rounding out the lin-
gual contour provides a crown breadth of 9.4 mm. This
is associated with a (reduced) mesiodistal length of 7.9
mm (estimated original length: 8.3 mm), cervical
length and breadth of 5.8 and 7.8 mm, respectively, and
a maximum root buccolingual diameter of 7.8 mm. The
attritionally reduced buccal crown height is 8.2 mm; the
buccal root length is currently 13.3 mm, but it was origi-
nally 1–2 mm longer.
The one meaningful comparative external tooth mea-
sure, given wear and available comparative data, is
crown breadth. The comparative samples are signifi-
cantly different from each other (P50.006) (Fig. 10),
and the Oliveira 9 estimate of 9.4 mm places it above
the Neandertal mean (9.1 60.7 mm, N550) and near
the upper limits of the early modern human samples
(MPMH: 8.8 60.5 mm, N58; EUP/MUP: 8.6 60.5
mm, N527). It is a moderately large P
3
for the Late
Pleistocene.
Possible associations
Oliveira 5 to 7 derive from the same stratigraphic
complex as Oliveira 3 (layers 17 and 18). Oliveira 3 and
7 are right humeri, and both preserve the proximal olec-
ranon fossa; they therefore derive from different individ-
uals. Oliveira 5 and 6 could derive separately or together
from either of these individuals. Oliveira 8 and 9, both
right mandibular teeth, come from the same layer and
could well derive from the same hemi-mandible if Oli-
veira 8 is an M
2
or M
3
.
SUMMARY
These fragmentary human remains from layers 17, 18,

Oliveira 1 to 4 remains were attributed to the Neander-
tals based on the relative breadth of the Oliveira 1 pha-
lanx, the thin pillars of the Oliveira 3 distal humerus,
and the evenly convex contours of the Oliveira 4 tibial
diaphysis near midshaft (Trinkaus et al., 2007). These
additional remains confirm their Neandertal affiliation
through the relatively thin enamel of Oliveira 9
[although early modern human variation in this feature
is poorly known (cf., Bayle et al., 2010)] and the probable
diaphysis to length proportions of Oliveira 7 and implied
body proportions. The other remains and other aspects
of these specimens are morphologically undiagnostic.

The measurements and proportions include: the area of the enamel cap (mm
2
), the area of the coronal dentine (including the pulp
space) (mm
2
), the enamel-dentine junction (EDJ) length (mm), the average enamel thickness (AET) defined as the quotient of
enamel area and EDJ length (mm), and the relative enamel thickness (RET) defined as the AET divided by the square root of the
coronal dentine area (as a surrogate for tooth size) and multiplied by 100. Standard deviations are available only for some of the
measurements in Feeney et al. (2010).

... In this sense, large carnivores may act as erasing agents of essential evidence of modern and complex Neanderthal behaviour as understood by several authors (Binford, 1978;McBrearty and Brooks, 2000;Vaquero and Pastó, 2001) in a context of alternate use of the same caves. This could be the reason that a considerable number of Western European Neanderthal fossils display carnivore damage (see Fig. 3.3) when analysed taphonomically (Barroso Ruiz et al., 2006;Beauval et al., 2005;Harvati et al., 2013;Lorenzo et al., 2012;Puymerail et al., 2012;Quam et al., 2001;Trinkaus et al., 2007;White and Toth, 1991), which could reflect, for instance, the rapid modification and destruction of inhumation contexts (Camarós et al., 2017). ...

Dietary traits of individuals and populations of both Neanderthals and animals, are essential for the reconstruction of biotic interactions among species. These kinds of dynamic relationships with other living species in a shared environment can be seen as a major influence in evolution and ecology, and the timing and type of interaction could have driven many aspects of Neanderthal behaviour. This chapter is aimed at combining the different approaches to studying interactions between organisms or populations: dietary food webs of plants-animals (stable isotopes and tooth wear), animals-humans (stable isotopes) and more complex interactions between humans and other animals, mainly carnivores (based on taphonomy and zooarchaeology).

The karst system is situated approximately 40 km inland between 75 and 150 m.a.s.l., oriented in a NE-SW direction and is home to a network of cave passages and archaeological sites, namely Galeria da Cisterna, Gruta da Oliveira, Gruta da Aroeira and Galeria das Lâminas (GdL) (Figure 1).

The European climate during the Holocene period is characterised by frequent changes of temperature and precipitation. The North Atlantic plays a major role as a driver for European climate and is a dominant precipitation source, particularly for the western European and north African realm. Atmospheric pressure gradients over the Atlantic (North Atlantic Oscillation, NAO), Atlantic circulation patterns (Atlantic Multidecadal Oscillation, AMO) or positioning of the Atlantic jet stream have been suggested to be responsible for precipitation patterns across western Europe. However, proxy data provide an inconsistent picture on how precipitation responds to changes in the Atlantic realm such as changes of Atlantic temperature (IRD), atmospheric pressure (NAO), water circulation (AMO) or the jet stream. Here we present a record of speleothem-based winter precipitation amount from Portugal. The record covers most of the Holocene and demonstrates that wetter conditions were synchronous in western and southern Iberia during early and mid Holocene. The record also shows a correlation between increased winter precipitation amount in western Iberia and Atlantic cooling, evidenced by Bond events, between 10 and 4 ka.
... Neandertals and archaic Homo generally have been noted to have relatively thin lateral and especially medial pillars to the distal humerus, framing the olecranon fossa (Carretero et al. 1997;Yokley and Churchill 2006;Trinkaus et al. 2007;Bermúdez de Castro et al. 2012;Trinkaus 2012), whereas those of recent humans tend to be thicker. It remains unclear whether the difference is driven by variation in the pillar thicknesses or the breadth of the olecranon fossa ). ...

In this latest volume in the Human Evolution Series, Erik Trinkaus and his co-authors synthesize the research and findings concerning the human remains found at the Sunghir archaeological site. It has long been apparent to those in the field of paleoanthropology that the human fossil remains from the site of Sunghir are an important part of the human paleoanthropological record, and that these fossil remains have the potential to provide substantial data and inferences concerning human biology and behavior, both during the earlier Upper Paleolithic and concerning the early phases of human occupation of high latitude continental Eurasia. But despite many separate investigations and published studies on the site and its findings, a single and definitive volume does not yet exist on the subject. This book combines the expertise of four paleoanthropologists to provide a comprehensive description and paleobiological analysis of the Sunghir human remains. Since 1990, Trinkaus et al. have had access to the Sunghir site and its findings, and the authors have published frequently on the topic. The book places these human fossil remains in context with other Late Pleistocene humans, utilizing numerous comparative charts, graphs, and figures. As such, the book is highly illustrated, in color. Trinkaus and his co-authors outline the many advances in paleoanthropology that these remains have helped to bring about, examining the Sunghir site from all angles.

Objectives: Aims of the study are to initially describe and comparatively evaluate the morphology of the new Zhaoguo M1 upper limb remains, and contextualize upper limb functional adaptations among those of other worldwide Upper Paleolithic (UP) humans to make inferences about subsistence-related activity patterns in southwestern China at the Pleistocene-Holocene boundary. Materials and methods: The preserved Zhaoguo M1 skeletal remains include paired humeri, ulnae, and radii, among others. These specimens were scanned using micro-computed tomography to evaluate internal structural properties, while external osteometric dimensions of the Zhaoguo M1 upper limb elements also were acquired. Both sets of measurements were compared to published data on Neandertals, and Middle and Upper Paleolithic modern humans. Results: The upper limb elements of Zhaoguo M1 display a suite of characteristics that generally resemble those of other contemporary Late UP (LUP) modern humans, while robusticity indices generally fall within the upper range of LUP variation. The Zhaoguo M1 upper limb elements display fewer traits resembling those of late archaic humans. The Zhaoguo M1 individual exhibits diaphyseal asymmetry in several upper limb elements suggesting left hand dominance. When evaluating the full range of magnitudes of humeral bilateral asymmetry in the comparative sample, Zhaoguo M1 falls at the lower end overall, but yet is relatively higher than contemporary LUP modern humans specifically from East Eurasia. Discussion: The Zhaoguo M1 individual suggests typical LUP modern human upper limb morphology persisted in southwest China until the end of the last glacial period. Upper limb bone asymmetry of Zhaoguo M1 also indicates that behavioral activities attributed to a hunter-gatherer tradition apparently extended through the Pleistocene-Holocene transition in this region.
... The existence of Aurignacian occupation in southwestern Iberia has been debated (Zilhão, 1997;Straus et al., 2000;Zilhão and Trinkaus, 2002;Trinkaus et al., 2007;Zilhão et al., 2010;Peña Alonso and Vega Toscano, 2013;Bicho et al., 2017). Recently, the Bj-13-12 layer lithic assemblage of the Bajondillo Cave (see Fig. 1) has been attributed to the Early Aurignacian or Proto-Aurignacian based on the presence of blades and bladelet cores and the 43-41 cal yr BP dates (Cortés-Sánchez et al., 2019). ...

The timing of the Neanderthal-associated Middle Palaeolithic demise and a possible overlap with anatomically modern humans (AMH) in some regions of Eurasia continues to be debated. The Iberian Peninsula is considered a possible refuge zone for the last Neanderthals, but the chronology of the later Middle Palaeolithic record has undergone revision and has increased the debate on the timing of Neanderthal extinction. Here we report on a study of the 5-m-thick archaeological stratigraphy of the Cardina-Salto do Boi, an open-air site located in inland Iberia, from which optically stimulated luminescence (OSL) ages were obtained for Middle and Upper Palaeolithic occupations preserved in overbank alluvial deposits. Geomorphology, archaeostratigraphy, stone-tool evolution, and OSL dating support the persistence of Neanderthals after 41 ka in central Iberia; the transition between the Middle Palaeolithic material culture and the AMH-associated Aurignacian blade and bladelet production is estimated to lie between 34.0 ± 2.0 ka and 38.4 ± 1.9 ka. Our results demonstrate that investigations focusing on different geomorphological situations are necessary to overcome the current limitations of the evidence and to establish more consistent models for Neanderthal disappearance and AMH expansion in the Iberian Peninsula.
... The comparative and morphometric analysis of the many Neanderthal teeth found in important Eurasian sites (e.g., Krapina, see Gorjanovic-Kramberger, 1906) significantly contributed to enriching our understanding of the biology of these past human groups. In particular, and despite the fragmentary nature of the fossil record, it has demonstrated its value to estimate individual, population, and tempo-spatial variability (Bayle et al., 2009;Crevecoeur et al., 2010;Willman et al., 2012;Garralda et al., 2014a;Trinkaus and Walker, 2017). The alterations related to para-and non-masticatory activities affected dental morphology during life, and thus offer important evidence about the behavior of the studied individuals (Garralda et al, 2004;Le Cabec et al., 2013). ...

Few European sites have yielded human dental remains safely dated to the end of MIS 4/beginning of MIS 3. One of those sites is Marillac (Southwestern France), a collapsed karstic cave where archeological excavations (1967-1980) conducted by B. Vandermeersch unearthed numerous faunal and human remains, as well as a few Mousterian Quina tools. The Marillac sinkhole was occasionally used by humans to process the carcasses of different prey, but there is no evidence for a residential use of the site, nor have any hearths been found. Rare carnivore bones were also discovered, demonstrating that the sinkhole was seasonally used, not only by Neanderthals, but also by predators across several millennia. The lithostratigraphic units containing the human remains were dated to ∼60 kyr. The fossils consisted of numerous fragments of skulls and jaws, isolated teeth and several post-cranial bones, many of them with traces of perimortem manipulations. For those already published, their morphological characteristics and chronostratigraphic context allowed their attribution to Neanderthals. This paper analyzes sixteen unpublished human teeth (fourteen permanent and two deciduous) by investigating the external morphology and metrical variation with respect to other Neanderthal remains and a sample from modern populations. We also investigate their enamel thickness distribution in 2D and 3D, the enamel-dentine junction morphology (using geometric morphometrics) of one molar and two premolars, the roots and the possible expression of taurodontism, as well as pathologies and developmental defects. The anterior tooth use and paramasticatory activities are also discussed. Morphological and structural alterations were found on several teeth, and interpreted in light of human behavior (tooth-pick) and carnivores' actions (partial digestion). The data are interpreted in the context of the available information for the Eurasian Neanderthals.

Late Pleistocene hominins co-evolved with non-analogue assemblages of carnivores and carnivorous omnivores. Although previous work has carefully examined the ecological and adaptive significance of living in such carnivore-saturated environments, surprisingly little attention has been paid to the social and cultural consequences of being-with, and adapting to, other charismatic predators and keystone carnivores. Focusing on Neanderthal populations in Western Eurasia, this paper draws together mounting archaeological evidence that suggests that some Late Pleistocene hominins devised specific behavioral strategies to negotiate their place within the vibrant carnivore guilds of their time. We build on integrative multispecies theory and broader re-conceptualizations of human-nature relations to argue that otherwise puzzling evidence for purported ‘symbolic’ behavior among Neanderthals can compellingly be re-synthesized with their ecology, settlement organization and lifeworld phenomenology. This re-framing of Neanderthal lifeways in the larger context of startling carnivore environments reveals that these hominins likely developed intimate, culturally mediated, and hence varied, bonds with raptor, hyena and bear others, rather than merely competing with them for resources, space and survival. This redressing of human-carnivore relations in the Middle Paleolithic yields important challenges for current narratives on evolving multispecies systems in the Late Pleistocene, complicating our understanding of Late Quaternary megafaunal extinctions and the roles of hominins in these processes.

The dental and alveolar remains of the Upper Paleolithic early modern humans from the Abri de Cro-Magnon (Dordogne, France) are described and reassessed, building on descriptions since their discovery in 1868. There are four individuals represented; two (Cro-Magnon (CM) 4253 and 4254) are portions of numbered skulls (Cro-Magnon 1 and 2) and two (Cro-Magnon 4256 and 4257/58) are unassociated but likely deriving from Cro-Magnon 3 and 4. CM 4253 exhibits advanced periodontal lesions, likely secondary to tooth wear, CM 4256 has moderate alveolar resorption, but the others show little alveolar pathology. CM 4253, 4256 and 4257 have premolar rotation, and CM 4257/58 had impacted M3s. The CM 4254 molars are average in size for the Late Pleistocene, but those of CM 4257/58 are at or beyond the upper limits of known ranges of Upper Paleolithic variation. Only the dental dimensions of the CM 4257/58 molars are exceptional for earlier Upper Paleolithic humans.

Despite the recent re‐datings of several key sites that have cast doubt on late survivals, it continues to seem to be the case that Aurignacian (sensu lato) industries appeared relatively early in northern Spain, but not in southern Spain or Portugal. Although arguments for extremely late survival in Gibraltar are questioned, new information from sites in Murcia and a more conservative reading of the Gorham's Cave record seem to support the thesis of late Middle Paleolithic survival and late early Upper Paleolithic arrival in the south. Major problems continue to be the lack of either Neanderthal or Cro‐Magnon human remains of late Middle Paleolithic or early Upper Paleolithic age in Iberia and the ambiguity of the Châtelperronian record in northern Spain.

A few meters above the karstic spring of the Almonda River, there is a cave entrance that gives access to an extensive network, several kilometers long, of underground galleries. In the first few meters of that cave, shallow archeological deposits from different time periods (Upper Paleolithic and Neolithic; Copper, Bronze and Iron Ages) have been known to exist since the 1930's. As a result of a program of systematic speleoarcheological exploration of the system, began in 1989 and continuing, Lower and Middle Paleolithic deposits were also discovered (ZILHAO et al. 1991, 1993). These earlier deposits are located in two different areas pig. 1): the fossil galleries above the spring; and the EVS zone, several hundred meters upriver, in deep galleries subject to Winter flooding. Uranium-Thorium dates for some of these contexts have been obtained (Table 1). In this paper they will be presented and briefly discussed.

Dental anthropologists focus on the variation around a commonly shared pattern, a variation expressed by differences in tooth size and morphology. This book centers on the morphological characteristics of tooth crowns and roots that are either present or absent in any given individual and that vary in frequency among populations. These nonmetric dental traits are controlled largely by genetic factors and provide a direct link between extinct and extant populations. The book illustrates more than thirty tooth crown and root traits and reviews their biological and genetic underpinnings. From a database of more than 30,000 individuals, the geographic variation of twenty-two crown and root traits is graphically portrayed. A global analysis of tooth morphology shows both points of agreement and disagreement with comparable analyses of genetic and craniometric data. These findings are relevant to the hotly contested issue of timing and geographic context of modern human origins.
