At a press conference yesterday, researchers announced the completely unexpected: a Siberian cave has yielded evidence of an entirely unknown human relative that appears to have shared Asia with both modern humans and Neanderthals less than 50,000 years ago. The find comes courtesy of a single bone from individual's hand.
The authors also briefly touched on a separate issue: this ability will be unevenly distributed in space and time. DNA simply lasts longer in cool climates, as evidenced by the recent announcement that DNA had been obtained from a polar bear sample that was over 100,000 years old. So, any species that was stuck near the equator—like the hobbits—are unlikely to be in on the DNA revolution. This is especially unfortunate given the fact that, as noted above, a lot of the most interesting action in hominin origins seem to have been taking place in Africa.

I've always thought that as soon as Homo sapiens started conquering the planet we started killing every other type of Homo species. They walked around like us, but were not as smart as us verbally and technologically. We invaded their land and killed them because they were different.
Dr. TATTERSALL: Yeah, Ardipithecus, of course, is the subject of great debate, and whatever it is, it seems to be really sort of an outlier in human evolution. And of course, it's four million years old and represents a very early stage in the history of the human family. This specimen, being only about 40,000 years old, plus or minus, represents a much more recent relative of ours, and it's very it's very tantalizing because it's distinct from Homo sapiens, and yet, clearly, it's not in the region today. The same thing happened in Europe where the Neanderthals, Homo sapiens comes in right around that time, 40,000 years ago, and pretty soon, the Neanderthals are gone. And the same thing happening also in Eastern Asia with Homo erectus that had been there for a long, long time - last date is around 40,000 years ago -and after that, only Homo sapiens. So there's a sort of a pattern developing here.

Why did the other species vanish when the "sapiens" appeared on the scene?
I need a credible answer that doesn't include bad weather....anyone?
