- Michael Pfeiffer added an answer:3Does anyone know an analogy for chrysoprase beads in the Gulf region?
We've found a chrysoprase bead in a tumulus grave in Kuwait. The burial is multiple and multi-phase but most of the equipment suggest dating for Neolithic. This bead (biconical, with chamfered perforation) does not look like typical Neolithic ornament from the Gulf region. I have not found any analogy until now, neither from Neolithic nor from the later periods.
You might consider googling the Society of Bead Researchers. The have both an annual journal and quarterly newsletter where one can pose research questions. About half of the Society are archaeologists.Following

Fire, feature of tools …
Thank you, dear archaeologists and paleoanthropologist
I'm not sure about "ornament" in the paleolithic, and I have been trying to remember where did I read about this, but there are concrete examples of "ornament" in neolithic objects: bone "tools" and "objects" with surface embellishment recorded in James Trilling's The Language of Ornament. As I said, Christopher Tilley's The Materiality of Stone studies surface embellishment on menhirs while discussing their utility of beyond mere "termini" or location posts upon the landscape... Trilling's book is meant for a general reader, but his images are quite good. Tilley is an expert on neolithic stone monuments and has written at length about the subject, as also Richard Bradley's Rock Art and the Prehistory of Atlantic Europe: Signing the Land. Tilley takes more risks than Bradley in interpreting those objects or pondering about their "ornamental" traits.Following

- 72There are quite a few hypotheses to explain early human evolution: Are there ANY that explain the evolution of H. neand. and H. sapience?Negative answers will also be appreciated. See Anton and Snodgrass 2012, Wrangham 1999, Ungar 2006, Bunn 2007, Stanford 2001
Is Homo's brain growth +-continuous? It's seen in the fossil record since about 1.8 Ma, when H.erectus-like people dispersed intercontinentally (e.g. the Mojokerto child (possibly 1.8 Ma) is estimated to have had more than 800 cc as an adult). OTOH, late-Pleistocene H.sapiens had a somewhat smaller brain that earlier neandertals.
In other animals, dramatic brain expansions are typically seen in (semi)aquatics, e.g. porpoises, seals, otters etc have 2 or 3 times larger brains than equally large terrestrial relatives. There's no reason to think that humans were an exception among other animals: we developed larger brains when our early-Pleistocene ancestors followed the African & Eurasian coasts & rivers, dipersing intercontinentally. This might be due to the abundant brain-specific nutrients in aquatic & especially littoral foods: poly-unsaturated fatty acids (e.g. docohexaenoic acid DHA), taurine, iodine & other minerals etc. (work of D.Horrobin, M.Crawford, S.Cunnane etc.).
But then: humans (not-aquatic (any more?)) don't always have access to littoral foods, but we nevertheless have very large brains: how to explain that? I'd think that's one of the reasons why sapiens probably has a longer youth than earlier Homo species, why coastal people are often healthier & larger-brained than mountain people (esp.before the introduction of iodine in salt), why sapiens has a slightly smaller brain than neandertals, why many humans like to have their vacation at the coast (iodine), and why we (still?) like eating fish, seafood & coconuts?Following
- 32Did all or most of the Homo or Australopithecus naledi fossils erode from the breccia in the roof of the naledi cave?
I just read that the first naledi fossil was a mandible which had collapsed from the breccia above. The morphological comparative evidence is clear IMO: naledi (humanlike plantigrade feet, more flamingo- than ostrich-like) were wetland waders, who collected aquatic herbaceous vegetation (& probably other foods) like lowland gorillas regularly & bonobos occasionally do, but much more frequently: this also explains their bonobo-like features, e.g. the curved manual phalanges (for climbing in the branches above the swamp like bonobos do). When they died in the swamp, their bodies got almost immediately covered with mud, which could explain why the fossils are remarkably complete. But I'm no geologist: the caves below the wetland eroded away, but how exactly could the fossils end up in the Naledi cave?
<http://ncse.com/blog/2015/10/cave-homo-naledi-textbook-example-how-to-do-science-0016693#comment-2319909560>I>; "I am a member of the club who made the discovery of the Naledi Fossil ... The cave itself has been known to us and visited frequently for as long as I have been a member of the club. It has indeed been well surveyed and what initially started as 3 different cave systems were all eventually interconnected to create 1 large system. The fossils were discovered in a section known as the Dragon's Back. This section was visited and surveyed and has never seen visitors since the survey was first created (I stand to be corrected but I believe 1980s). A new adventurous member of the club - Steven - set out to re-explore the cave. His visit to the chamber was met with the discovery of the first mandible which had collapsed from the breccia above. It was more a matter of good luck and 20 years of nature's impact that led to the discovery ..."
"Collapsed from the breccia above". A.sediba & other S.African australopiths also came from breccia.
Can it be checked whether some or all naledi fossils came from the roof: then the roof should still contain fossils, I'd think? If they fell piecemeal, as the discoverer said, how often does this happen? If every year 1 fossil falls from the roof, this could explain the accumulation in 2 or 3 mill.yrs? But the illustrations in the articles show also Dragon's Back, which is an enormous rockfall: a whole block of rock at once fell down?
A.boisei fossils are typically found amid papyrus swamps (G.Conroy) & lagoons (J.Carney), and A.afarensis Lucy was found amid crocodile eggs & crab claws (D.Johanson). When they died in the swamp, their bodies got soon covered with mud: Lucy was found amid "crocodile and turtle eggs and crab claws" (Johanson & Taieb 1976), boisei at Olduvai was found in "lake-margin deposits ... swamp vegetation ... some kind of reed ... marshland and/or shallow water" (Conry 1990). If gorillas & bonobos find foods in swamps etc., there's no reason why naledi wouldn't have found (part of) its food in comparable wetlands (which were possibly a lot more abundant there in the much hotter & wetter Pliocene - there has been an uplift of this region sine naledi's time)? Where the Nariokotome Boy (H.ergaster) was found, the aquatic component of the environment was clear (e.g. different spp of catfish, swamp-snails, turtles, reed, hippo footprints), but the naledi environment might have been +- different (e.g. google illustrations ate "bonobo wading" or "gorilla bai"), and has (or can? cf preservation etc.) the naledi bed already been described in detail? In ancy case, naledi's morphology is clear: the combination of curved hand bones + flat feet is explained by an aquarboreal lifestyle as still sometimes seen in lowland gorillas & bonobos in search for floating frogbit, sedges or waterlilies, but more frequently (hence naledi's flatter feet & smaller front teeth).Following
- Deborah Swartz added an answer:22What diseases can cause such changes in the mandible?
Dear friends! The jaw belongs to a teenager of 15 years, 15 thousand years Paleolithic. What diseases can cause such changes in the mandible (besides scurvy)?
Just throwing out the idea of infection. Also, soil action can
imitate pathologies. (My dentist swore, upon seeing an
excavated mandible, that bone loss was due infection,
when it could have been due to soil conditions.) Was the
soil acid? Any plant roots active in the soil?

- 8Do coastal macaques have (slightly) thicker tooth enamel than inland macaques or than non-tool-using macaques?
Are there comparative studies of enamel thickness among Macaca spp & related monkeys? Macaques are omnivores who seem to have dispersed out of Africa along the Indian Ocean coastal forests unto SE.Asia, even Sulawesi. I have hypothesised that mid-Miocene hominoids followed the Indian Ocean coasts (first hylobatids, later pongids) and the Western Tethys coasts (hominids in coastal forests of the archipelagoes of the later Medit.-Black-Caspian Seas). Many early great hominoids had thick enamel, possibly for hard-object feeding (durophagy), which might also explain why all great apes (sometimes or often) use tools. Is durophagy to be expected more frequently in coastal than in inland forests?
Thank you very much, Amanda. I"ve send your answer to our AAT discussion group.
Some possibly relevant thoughts on durophagy. Alan Shabel found resemblances of the dentition of the robust australopiths with those of Carnivora that eat hard-shelled invertebrates (HSI). Lloyd du Brul OTOH saw convergences between the robust dentition & the giant panda's, e.g. flat broad face, enormous molars, premolar molarisation. Pierre-François Puech (who first studied afarensis' enamel micro-wear electron-microscopically) said the glossy polished appearance of afarensis' enamel suggst they fed on wetland plants (e.g. parts of papyrus sedges according to the paleo-milieu & to isotopic studies); the thick enamel might have been for calorie-poor diets, but possibly also for protecting the enamel against small snails or so living on certain wetland plants? Macaques are omnivores: fruits, insects, crops, young leaves, small animals (incl.HSI). Capuchin monkeys & clawless otters also eat HSI; sometimes they lay the bivalves in the sun, so they can be opened more easily after some time.Following

- 11Why was human evolution possible despite the remarkable phenotypic flexibility of humans?A basic idea underlying the evolutionary approach to cognition is that serious changes in behavior are consequences of alterations in the genome. However, this assumption is wrong for our species. Indeed, the children of hunter-gatherers and farmers may become stock brokers and coders simply because farming was a standard occupation for one generation and coding is a typical occupation for the following generation. If our species is so flexible then it is reasonable to assume our ancestors were very adaptive too and able to adjust phenotypically to any situations. Then why after the emergence of bipedalism human evolution took place? Such answers as because only our species has some unique characteristics (language, etc.) do not seem interesting.
For José Joordens' paper, google e.g. "joordens erectus nature 2014" or so: about 1.2 mill.yrs ago, H.erectus used shark teeth to open freshwater shells: it was probably a large river not far from the sea. In any case, it confirms that Pleistocene Homo dispersed along the African & Eurasian coasts & rivers rather than running over open plains.Following

- k.a Galil added an answer:16Are there any articles available on what causes this morphology in the roots of the teeth?This is a skeleton of an old kingdom mummy, my colleagues and I had noticed the roots of the teeth mainly in the maxilla have developed these mineral growths. It seems to have occurred primarily on the molars but there are also signs of it on the premolars. We believe this is due to the body reacting with the natron salt.
Any advice would be helpful.
hello: i believe its natron salts. and residues of mummification
if you look at your picture the original one you will notice several areas same as he one you are describing and natron slats are famous for doing that. i have an experience with Egyptian mummies and i have x-rayed all the Royal mummies in Cairo museum with the university of Michigan and Alexandria University in Egypt.
We published a book by the title of X-raying the pharaohs published by Scribner and i saw items like yours.
As an oral histologist and Periodontist Professor ,i can see some of my colleagues think it is an enamel pearl or cementoma or excementosis ,for the record most cementomas are at the apics of the tooth not wher it is located in your sample
true some of what you mention is in the ares of enamel pearl and cementomas or excementosis .
.even x-ray would be hard to identify because of superimposition also not sure if you can scrape it (but if you can scrape it )neither enamel Pearls and or excementosis will come out but natron salts will fall off easily and can be analyzed chemically easily
natron generally is ;sodium chloride (table salt), sodium carbonate, sodium bicarbonate, and sodium sulphate. But there is more than natron in mummification.
take for example Dr zaki iskander one of the best archaeologist Egypt wrote that natron was not the only substance used for mummification the cranial cavity was stuffed with resin or linen soaked in resin.
further more the mummification process used cinnamon,myrrh,cassia ,linen,linen soaked in resin ,saw dust,natron,and occasionally one onion the hole body was anointed with cedar oil and rubbed with myrrh (from the brief history of ancient egypt by Zaki Iskandr and Alexander Badawi published in Cairo madkur 1965

- Wolfram Meier-Augenstein added an answer:1Is chronic alcohol use recorded in the stable isotope composition of hair?In the past, I have heard that alcoholism can be identified via stable isotope analysis (C, N, O, S, H) of human hair. I vaguely recall this being applied to an Andean mummy. Does anyone know of any good papers on this subset of stable isotope ecology?
Would you happen to recall where you might have heard about this? To the best of my knowledge there is no peer reviewed paper published reporting alcoholism having been determined through stable isotope analysis of hair. The few papers linking a particular stressor or metabolic state (e.g. anorexia nervosa) to a change in hair stable isotope signature vs normal healthy values were always based on a priori knowledge, i.e. only subjects known to suffer from a particular condition were studies and compared to healthy controls. These studies all share a common flaw, namely to conclude / claim stable isotope analysis of <insert element/s of choice here> could be used to detect / diagnose a particular condition. However, none of these papers ever reported if blinded studies had been carried out and, if what the results were.
IMCO to analyse hair for stable isotope abundance of CHNOS and to conclude unequivocally observed data are causally linked to alcoholism and nothing else is a stretch to put it mildly.Following
- Peter J Richerson added an answer:21What are your thoughts on the origin of science?I recently published my book "The Origin of Science" which can be downloaded at https://www.researchgate.net/profile/Louis_Liebenberg/publications/ I am interested in alternative theories on the origin of science and how this debate can lead to a better understanding of how our ability for scientific reasoning evolved.I have long been a fan of Louis' idea that tracking requires most of the skills that later led to science. I think one reason why it is such a good example is that it is social and cumulative. Cognitive advances at the individual brain level were probably required for tracking and similar tasks, though proving that may be hard. Chimpanzees and some birds, such as corvids and parrots, seem awfully smart as individuals. What humans have in addition to cognitive "right stuff" is social learning. Neophyte trackers acquire a huge amount of natural history knowledge that has accumulated in expert hunting groups for many generations. Plus, any given tracking exercise is an exercise in social back and forth so that expert trackers collaborate on tough problems. If there is a neophyte with them, he learns from the expert interchanges. Occasionally, some given hunt may lead to a novel observation that is incorporated into the large body of extant natural history.
I wonder if other tasks in hunter-gatherers make similar demands. What about tool-making, gathering and cooking? Perhaps tracking is just a particularly dramatic example because important decisions have to be made rapidly on the basis of enigmatic evidence and success or failure is evident pretty immediately. I imagine that other tasks use the same skills but in a temporally more drawn-out way.
My coauthors and I recently wrote a couple of papers arguing for the importance of social learning and cumulative culture in humans:
