Origin of Modern Humans

Every few years a paper comes out "explaining" short stature in one or more Pygmy groups. Most of the time the new work ads new information and new ideas but fails to be convincing. This is the case with the recent PNAS paper by Migliano et al.
From the abstract:
Explanations for the evolution of human pygmies continue to be a matter of controversy, recently fueled by the disagreements surrounding the interpretation of the fossil hominin Homo floresiensis. Traditional hypotheses assume that the small body size of human pygmies is an adaptation to special challenges, such as…
gregladen | December 11, 2007There seems to be some interesting things going on with the recently reported study of rates of evolution in humans. We are getting reports of a wide range of rather startling conclusions being touted by the researchers who wrote this paper. These conclusions typically come from press releases, and then are regurgitated by press outlets, then read and reported by bloggers, and so on. Here is, in toto, the press release from the University of Wisconsin, where John Hawks, one of the authors of the study, works. I reproduce the press release here without further comment.

gregladen | November 12, 2007You can now read the Krause et al (2007) paper from Current Biology regarding the FOXP2 variant found in Neanderthals in an open-access on-line form at Current Biology Online.
Here is the summary of the article:
Although many animals communicate vocally, no extant creature rivals modern humans in language ability. Therefore, knowing when and under what evolutionary pressures our capacity for language evolved is of great interest. Here, we find that our closest extinct relatives, the Neandertals, share with modern humans two evolutionary changes in FOXP2, a gene that has been implicated in…

There is a ceremonial burial in Britain .. ceremonial because it has some red stuff smeared on bone ... that has now bee dated to a few thousand years earlier than previously thought (to ca 25,000 years old).
Age of earliest human burial in Britain pinpointed from PhysOrg.com
The oldest known buried remains in Britain are 29,000 years old, archaeologists have found - 4,000 years older than previously thought. The findings show that ceremonial burials were taking place in western Europe much earlier than researchers had believed.
