> Men die off completely after 5 million years (because of a weakening of the 'Y' chromosome). This timeline is pure fantasy. The human race (homo sapiens) has existed for 200,000 years. In another 200,000 years we'll have been replaced by some species nearly unrecognizable to us, perhaps more intellectually advanced, but perhaps less so, whatever nature requires, in the endless march of evolution. But in five million years, there won't be any tangible sign of our existence except to a hypothetical future archaeologist from some species we cannot possibly imagine. Enjoy nature's gift of life -- we're a brief diversion in a long, long story that is not about us.
