Very interesting study - they found remains from 5 individuals dated at 1.8 million years (link) (http://www.nytimes.com/2013/10/18/science/fossil-skull-may-rewrite-humans-evolutionary-story.html?hp&_r=0).

The really exciting thing is that given the new method extracting single-chain DNA segments from fossils and sequence them, and the relatively recent discovery of these fossils in Georgia (minimal DNA contamination from modern humans) we will have genomic data of these skulls in the near future.

Wow, I expected John Hawks would have an interesting analysis, and he does not disappoint!

I waited to say anything because I was rather sure John Hawks would comment on this at some point, and that point has come: The new skull from Dmanisi (http://johnhawks.net/weblog/fossils/lower/dmanisi/d4500-lordkipanidze-2013.html). As we coelacanth science bloggers like to say: read the whole thing. But I do have a small point to add: Johnís model of descriptively episodic and punctuated expansions followed by long equilibria of regional localization tempered by gene flow may be characteristic of many medium to large Pleistocene mammals. To see where Iím coming from, please read Genome Sequencing Highlights Genes Under Selection and the Dynamic Early History of Dogs. Focus on the section in regards to the bottleneck of wolves.

The "out of Africa" discussion has been moved to a new thread dedicated to it. http://www.anthrogenica.com/showthread.php?1486-Did-modern-humans-come-out-of-Africa

A new study suggests that multiple species were present at Dmanisi (link (http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0088212)), contradicting the Lordkipanidze single species theory.
