Denisova II

I came across another article on the Denisova find here, on Spiegel-online, which includes a nice little slideshow (or in english), and John Hawks wrote a few more lines on it too.

Below the abstract of the letter in Nature:

Abstract

With the exception of Neanderthals, from which DNA sequences of numerous individuals have now been determined, the number and genetic relationships of other hominin lineages are largely unknown. Here we report a complete mitochondrial (mt) DNA sequence retrieved from a bone excavated in 2008 in Denisova Cave in the Altai Mountains in southern Siberia. It represents a hitherto unknown type of hominin mtDNA that shares a common ancestor with anatomically modern human and Neanderthal mtDNAs about 1.0 million years ago. This indicates that it derives from a hominin migration out of Africa distinct from that of the ancestors of Neanderthals and of modern humans. The stratigraphy of the cave where the bone was found suggests that the Denisova hominin lived close in time and space with Neanderthals as well as with modern humans.

Denisova: mtDNA of previously unrecognized, extinct human species?

Just a quick note today. In Nature an article was published, in which the news was revealed that the mtDNA extracted from a 48 – 30 kya old fingerbone, found at the Denisova Cave in Siberia,  might represent an until now unkown human species. However, this is far from certain yet. But still, this is very exciting news, and it shows once more that we are far from knowing it all yet.

So, before you believe the hype, have a good look at John Hawk’s commentary first, okay?
