Re:Reintroducing extinct species (Score 1)

You don't need as many originals as you would expect. There was a program to save the Mongolian Wild Horse or Przewalski's Horse from extinction when there were just 13 samples in zoos around the world. With careful breeding control, that number is over one hundred now, though I don't have the exact number. With so few samples, there is probably a lot less in the genetic pool than there was, but it's better than not having them at all.
