The fact that modern humans can be traced to a small group of ancestors does NOT imply that the race nearly went extinct. It just means that a small group of mutants 70,000 years ago went on to dominate the world. There were plenty of hominids that were driven to extinction not by a harsh environment but by these 2,000 and their descendants.
