Ten to twelve thousand years ago, the cheetah suffered a massive dieoff. Prior to this, there had been many different species, but only a small number of the modern species survived. It is from this remnant population that all cheetahs alive today have descended. As a species, they are genetically identical, with only 2% genetic variation compared with 10% or more in other cats. A skin graft from any cheetah will grow normally on any other cheetah in the world, while a graft from any other cat will wither and die. The potential for a virus to wipe out large numbers is high because of the lack of variation in disease resistance. Source |
Civilisation hasn't been around for 10 to 12 thousand years! Mutations do occur and are responsible for a ton of evolution, but you need a huge amount of time.
