9.7-million-year-old teeth discovery in Germany could re-write human history DW: And how old are the teeth you've found? HL: Around 9.7 million years old. ... DW:No less has been said about this tooth than that the history of mankind now has to be rewritten… HL: Well you know it's a question that's been discussed for decades. New discoveries lead to new insights that may contribute to our knowledge about our own history, and this finding has that potential because the great ape species has a relationship to Homo sapiens. DW: So what's the big groundbreaking knowledge here? HL: The groundbreaking knowledge is that we have comparable finds only in East Africa. And these are much, much younger. These species are well known as Ardi and Lucy, and their canines look very similar to the one here from Eppelsheim, but they are only two, three, four or five million years old, and Eppelsheim is almost 10. So the question is: What has happened? They found hominid teeth in Germany that are twice as old as anything comparable found in Africa. This creates a bit of a problem.
