These fossil finds seem to contradict accepted evolutionary theory. What causes some scientists to hold on so tightly to them as proof of evolution?
The Dmanisi fossils do not contradict evolutionary theory. What they contradict – or, more accurately, modify – is some current thinking about human evolution. That’s not surprising: with their mixture of erectus (or ergaster) and habilis traits, the Dmanisi fossils aren’t quite like anything that has ever been discovered before. Their anatomy comes as no great shock, however; fossils like them would have to have existed if erectus evolved from habilis. No-one, though, would have expected to find such fossils outside Africa. Because they are more primitive than any other hominid fossils previously found outside Africa, the Dmanisi fossils can hardly help but cause a reevaluation of current scenarios about human evolution and migration. This is not struggling to maintain belief in evolution in spite of the evidence, as ICR would have it, but adapting to new evidence which is an essential part of good science. Not only are these fossils entirely consistent with evolutionary theory, their
