Quite a while ago again, I wrote a few words on the A. Sediba finds. The fossils have been controversially described as the ancestors of Homo. Now a number of specialists have met at two occasions and discussed the fossils. … Continue reading
So now, of course, I can’t not draw your attention to the ~2mya Malapa Cave (South Africa) finds just published in Science, esp. as one of the authors has his home as the same university as I do (Zürich, Switzerland). The two partial skeletons, MH1 and MH2 are dubbed Australopithecus sediba. Who would want to miss out on the rare opportunity to name a new species, eh?
I haven’t read the articles yet, but I am sure to do so soon. John Hawks has already some usefull comments on his blog.
Below the abstract of the main article in Science and the ref to the second article. It’s also worth to have a look at the website of the University of Zürich and the videos there, even if you don’t understand much German. The main video doesn’t show much of the bones, but is subtitled in English. What’s rather nice, is that Schmid and colleagues say that they want to keep the material available for and share it with other researchers, incl. the original material. Continue reading
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:

The complete mitochondrial DNA genome of an unknown hominin from southern Siberia

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.
