Document Summary
A daring idea- that dna could be recovered from fossils. We are in the middle of two methodological revolutions. In the recovery of adna (pioneered at berkeley) In our ability to extract evolutionary inferences from adna sequences (with. The oldest adnas are less than a million years old (about 700,000 years old, from a horse) Neanderthals became extinct between 40,000 and 28,000 years ago adna recovered from fossil humans and our nearest relatives. There is clear evidence of genetic exchange among human groups. With adna we discover interbreeding between neanderthals and non-african humans. Denisova cave, with fossils at about ~30,000 to 48,000 years old. Turns out that the epas1 snps in tibetans are derived from the denisovans. And the evidence of genetic exchange continues to mount. Current view (out of africa, with some multiregional elements) Key to understanding our success is recognizing the origin of the hunter-gatherer lifestyle.
