A New Study on Homo floresiensis

Nature News mentions a new study on Homo floresiensis that concludes that the fossil is that of a microcephalic modern human. The study is actually published in PNAS (and if someone could send me a copy I would appreciate it – my email is in the about tab). Continue reading

Rickets, Neanderthals, And Lubenow: Part Two

In the previous post in this series I looked at vitamin D metabolism and the effects of vitamin D deficiency on the skeleton. So, lets talk about Lubenow and Neanderthals. Lubenows discussion of Neanderthals and rickets occurs in chapter 14. He begins the chapter by invoking the Genesis flood to explain the ice ages, which only lasted, according to Lubenow, for 700 years (give or take). Continue reading

Interesting Science Pictures: Part XII

This is from an article in PaleoAnthropology. The map, of the find locations for the Ngangdong specimens, hasn’t been seen in 75 years.

The article, Geometric morphometric analyses of hominid proximal femora: Taxonomic and phylogenetic considerations, looked at whether one can separate extant hominids into different taxa using geometric morphometrics and whether one could distinguish Homo from Australopithecus and Paranthropus.
