...recent fossil discoveries that supposedly document human evolution are mere opinions. Evolution has never been proved. It is a theory that is on shaky ground. ANDREW DIPROSE Rome...
...figuring out how they arose, how they were related and what they evolved into--those that weren't evolutionary dead ends--has proved elusive. Not only is the fossil record full of holes, but the hominid species from eastern Africa haven't shown up in southern Africa, and vice versa. A remarkably preserved skeleton found in South Africa's Sterkfontein cave could change all that. Believed to be at least 3.3 million years old, the bones may belong to A. afarensis, making it the first of Lucy's species uncovered in that area. But the skeleton hasn't been fully...
Just as australopithecus afarensis eventually gave rise to the genus Homo, so one species came to stand out among the Homo line and eventually led to modern humans. The fossil record is far too spotty to say how Homo habilis (handy man) and other members of its genus--H. rudolfensis, H. ergaster and H. erectus--were related, to what extent they overlapped or even whether they all represent distinct species. Many scientists believe, though, that it was H. erectus that was the ultimate victor, the direct ancestor of our own species...
...romantic notion of how the Neanderthals disappeared has been around for decades: perhaps they were eliminated by interbreeding with us. Maybe we all carry a bit of Neanderthal in our DNA. Two years ago, molecular biologists tested that hypothesis by extracting some DNA from a Neanderthal fossil and comparing it with that of modern humans. Their conclusion: the differences are great enough to rule out significant interbreeding, even though such mating would have been biologically possible...
