- Rusty Greaves added an answer:17Can anyone help me in finding literature/references about pregnancy in hunter-gatherer populations?
I would be interested in getting cross-cultural data about hunter-gatherer/foraging societies in relation to:
-pregnancy success (natural or induced abortions through pregnancy)
-mortality at birth (of both women and babies)
-mortality rate of newborns
I'm glad that Tom Headland weighed in, he has great longitudinal data for the Agta. I'm sure you are familiar with the second edition of Nancy Howell's "Demography of the Dobe !Kung" (2000, Aldine de Gruyter, New York) and Kim Hill and M. A. Hurtado's "Ache Life History: The Ecology and Demography of a Foraging People", 1996, Aldine de Gruyter, New York. You probably also have looked at Renee Pennington's Hunter-gatherer demography chapter that compares soem published data in Panter-Brick, C., R. H. Layton, and P. Rowley-Conway (eds), Hunter-Gatherers: An Interdisciplinary Perspective, pp.170-204, Cambridge University Press, Cambridge You should look at Karen and my Pume paper (2007 Karen L. Kramer and Russell D. Greaves. Changing patterns of infant mortality and fertility among Pumé foragers and horticulturalists. American Anthropologist 109 (4):713-726; or the Spanish version: 2010 Karen L. Kramer and Russell D. Greaves. Cambios en los patrones de mortalidad infantil y fertilidad entre cazadores-recolectores y horticultores Pumé: implicaciones para el crecimiento poblacional y desarrollo sostenible. Antropológica 54 (113):5-41.) Paula Ivey studied Efe ("Pygmy") women and allocare in the mid 1990s, she may have some demographic data, you can say that I suggested you contact her (email@example.com). If that email does not work I can get you in contact with her another way. Although the Semai data in Alan Fix's study were agricultural at the time of his work, they were a former hunter-gatherers group: A. G. Fix, 1977. The Demography of the Semai Senoi. Museum of Anthropology, University of Michigan, Anthropological Paper N0. 62, Ann Arbor. Did you have a chance to ask Karen about references when you saw her at CHAGS?Following

I had replied to this question earlier. I have made collection of the bone tools made by Narmada valley hominin ~70 Kya, which, subsequently got fossilized. You see my 2012 paper uploaded- in RG published in Current Science.

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)?
Dear colleagues! I'm working with the dental pathology analysis of this sample now, and on the second molars are the multiple pits which can be one of the forms on enamel hypoplasia.Following
- Zuzanna Wygnańska added an answer:2Does 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.
Thank you for sharing information about material and techniques from PPNA Syria - this is a useful trail. I'm familiar with Saieziu's publication but still nothing looks like this bead. It must have been something precious since they deposited only half of the bead in this grave.Following
- Catalin Lazar added an answer:16Does anybody know red ocher beads from neolithic or other prehistoric periods?
In the summer of 2014, we discovered a new Eneolithic cemetery at Sultana (Romania), and near one of the skeletons we identified a fragment of red ocher bead.
Does anybody know other similar artefacts from prehistory or other time periods?
Thanks in advance.
Thank you for the information.
- Marc Verhaegen added an answer: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
- Thomas J. Loebel added an answer:3Evidence for functional usage of Manganese dioxyde (MnO2)?Within the Mousterian record of western Europe, we have evidence for usage of black pigment made from MnO2 by Neandertals (50 000 years old at Pech-de-l'Azé I for instance). I've been using the analogy with the ethnographic record as well as some preliminary experiments to argue that they might have been used as dye stuff/stain (see Soressi et D'Errico, 2007 as well as Soressi et al 2008). Would anybody know of usage of MnO2 pigment for other purposes than body decoration/symbolic purposes?
I recommend reading:

- Jean-Luc Voisin added an answer:2What other country/region specific fossil site catalogs have been digitised?The fossil site catalog for Italy is a searchable database on the web (http://web.uniba.it/progettiricerca/catalogorestifossili/database/database_en/search_en.html). Is anyone aware of any others? There is the catalog of fossil hominids text from the 70's and some country specific supplements were published in the early 90's, but finding any searchable online databases would be much quicker than using the books.
I have discovered your question today. You might be interested by this database. It is for all the world. I do not know if it is complete, but many sites are recorded yet. This database is in English and Japanese. Please follow this link :
- John J. Crandall added an answer:8What could cause the eburnation on these toe bones?
This is an old kingdom mummy these are the only bone of the foot I have, cannot understand the cause of this polishing. Sadly the photo does not do it justice.
I'd recommend consulting Tony Waldron's work on Degenerative Joint Disease as this appears to be osteoarthritis. Jurmain's recent summary of joint disease and attempts to link these to activity in "A Companion to Paleopathology" (edited by AL Grauer) may also be helpful. Without large trends by age, sex and other variables, it is hard to say what this might mean in terms of who does what kinds of labor, etc. in any population. As others have noted, this is because OA/DJD are multifactorial and age, sex, and genetics matter.Following
- Chun Liu added an answer:62Do you think there are some fossilized tools that were judged mistakenly as lithic tools in historic archeology?
My personal view, hominids could use bones, horns, sticks and so on as tools. Just as these attached in the image.
the evidences are also overlooked.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

- Katalin Wolff added an answer:4Is anyone aware of missing bone elements taken away for research from the collections of Smithsonian Institution National Museum of Natural History?We are looking for missing bone parts removed from the parietal bones (25 mm/1 inch diameter) of several individuals skulls' (probably >100) from different populations from the NMNH Smithsonian Institution. They have been removed most likely in the 1950s by a researcher from Middle/Eastern Europe and the purpose of the study as far as we know, was to compare parietal bone thickness among different populations. If you are aware of the existence of these bone elements in your collection or any related articles please let us know! Many thanks!Dear Barbara, if you're missing these parts in the same size (mostly or always) from the right parietals approximately from the area of tuber parietale, it is highly likely that they have been collected for the same research! Unfortunately we don't know yet who and from where took away them and we are not aware of any publication related to the topic since probably it has been written on the language of the researcher that time. It would be really nice to find out whether these elements still exist somewhere?! We're working on it!Following
- 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:
