The Arched Metatarsal of Australopithecus afarensis

by Kambiz Kamrani in Anthropology.net

Carol Ward1, William Kimbel, and Donald Johanson have published a paper in Science on the arch seen in a newly discovered fourth metatarsal of Australopithecus afarensis (AL 333-160). A lot of the popular press are publishing misleading headlines that this … Continue reading →... Read more »

When & Were Grapes Domesticated

by Kambiz Kamrani in Anthropology.net

I got some archaeobotany for you to start your weekend off right with — a new open access study in PNAS announces a genome wide association of 8,000 years of grape domestication, spanning the Eastern Caucasus to Western Europe. Lead … Continue reading →... Read more »

Trampling Over The Dikika Cut Marks

by Anthropology.net in Anthropology.net

Well, I feel somewhat vindicated. Remember the post where I criticized hominin cut marks from over 3 million years ago? Others have also had an eye of suspicion and have published their concerns in PNAS this week. I was wrong in considering the croc marking differential to the cut marks. But I was not wrong [...]...

The Genetics & Linguistics Of Central Asia

by Anthropology.net in Anthropology.net

Both Razib and Dienekes have reviewed a paper on the population genetics of Central Asian peoples. To make sense of Central Asian ancestry has been challenging, to say the least. In particular, the problem is compounded by nomadic peoples without much written history nor uncovered archaeological record. What we do have are the linguistic, physical features, [...]...

A Curious Look At The 3.39 Million Year Old “Stone Tool Markings” From Dikika, Ethiopia

by Anthropology.net in Anthropology.net

I don’t know who this is worse for, the editors & reviewers over at Nature or the authors of the article who can’t tell the difference between crocodile teeth markings and stone tool modification, nor raise the possibility. The paper, “Evidence for stone-tool-assisted consumption of animal tissues before 3.39 million years ago at Dikika, Ethiopia,” very [...]... Read more »

Were The Americas Settled Twice?

by Anthropology.net in Anthropology.net

A team of paleoanthropologists report in PLoS One analyzed the skulls of several dozen 11,000 year old Paleoamericans and compared them to the skulls of more than 300 1,000 year old Amerindians. They concluded that based on the morphology, there were two distinct waves of colonizers from Asia. While we know from a couple genetic [...]... Read more »

Genetics of High Altitude Life

by Anthropology.net in Anthropology.net

Almost every biological anthropology text-book I’ve ever looked at has described the adaptations of human populations to the environments they occupy. Examples they give are the short stalky Inuit adapted to conserving heat in cold environments, the long lanky East African nomads adapted to far distant travels, and the barrel chested Peruvian and Tibetans living [...]...

The Genetics of DCC, Netrin & Mirror Movements Discovered

by Anthropology.net in Anthropology.net

From Nobel Intent comes news of a discovery in the Mendelian genetics of Mirror Movements, a condition that causes people to involuntarily move both sides of their body when they intended to only move one. Aside from being medically relevant, interesting on a population genetics level, and involved an Iranian family, it also caught my [...]... Read more »

Australopithecus sediba (UW88-50) of Malapa, South Africa

by Anthropology.net in Anthropology.net

Lee Berger’s son, Matthew, found the ~1.9 million year old hominin remains of female adult and a juvenile male in cave deposits at Malapa, South Africa. The remains have been analyzed and been published in Science today, and so far this finding is the big fossil hominid of 2010. The skull of the juvenile is the [...]... Read more »

Long Toes & Short Ankles Help Sprinters Accelerate Faster

by Anthropology.net in Anthropology.net

The Journal of Experimental Biology has published an interesting paper about some unique features in sprinters: longer toes and shorter ankle joints. The only one flaw is that their sample size is limited, they only compared 12 collegiate sprinters with 12 non-athletes of the same height. Regardless, from a physical anthropological point of view, this [...]... Read more »

Ancient Leishmaniasis From Coyo Oriente Cemetery In Chile

by Anthropology.net in Anthropology.net

I recently completed a medical parasitology course as part of my medical education. One of the diseases we discussed was leishmaniasis. Leishmaniasis is a zoonotic disease that is transferred to humans from reservoir hosts via the sand fly vector. The sand fly injects the promastigote form of the parasite, and the parasite invades white blood [...]... Read more »

An Improved Method On Calibrating The Human Mitochondrial Molecular Clock

by Anthropology.net in Anthropology.net

The American Journal of Human Genetics has published an article titled, “Correcting for Purifying Selection: An Improved Human Mitochondrial Molecular Clock,” in which a more accurate method of dating ancient human migration, even when no corroborating archaeological evidence exists, is announced.

How does was this done?

The authors started with a sample of 2,000 fully sequenced mtDNA [...]... Read more »

Mutatons in VLDLR gene in the Quadrupeds from Turkey

There first was this paper, “Cerebellar hypoplasia and quadrupedal locomotion in humans as a recessive trait mapping to chromosome 17p,” and then there was this paper, “A new syndrome with quadrupedal gait, primitive speech, and severe mental retardation ...

3,000 year old small body humans in Palau, Micronesia

by Anthropology.net in Anthropology.net

PLoS One completely surprised me today by releasing this paper, “Small-Bodied Humans from Palau, Micronesia.” The research comes from South African and American researchers, and the paper was edited by John Hawks, who apparently can really keep a secret it seems.

Were Homo floresiensis just a population of myxoedematous endemic cretin Homo sapiens?

by Anthropology.net in Anthropology.net

New research from the Proceedings of the Royal Society B raises the possibility that Homo floresiensis was nothing more than population of Homo sapiens that were endemic cretins.

“show that the fossils display many signs of congenital ... Read more »

Axel Visel’s talk on “The regulatory genome in human-specific evolution”

by Anthropology.net in Anthropology.net

Today I attended Axel Visel’s talk about his work in identifying enhancers specific to humans at the Primate Biology Group. It was a really awesome talk, and that’s because because I’m really interested in differential gene regulation and expression…. especially when it focuses on human evolution. The differences in gene expression and regulation has been ... Read more »
