For whatever reason, I've recently been interested in dog breeding, and it seems like you can pretty easily get a viable population from a really small amount of individuals. I've always heard that you need around ~100 people who are genetically diverse to found a human population, but our breeding practices, and the fact that there are records of extreme 'population bottlenecks' in the human population, as well as the fact that only two individual mammallian pests (rabbits, rats) were enough to create a viable population suggest to me that this is not true.
Can anyone point me towards the paper that the '60 people or more' thing comes from?
