When Darwin wrote On the Origin of Species, he assumed, due to the fossil record, that species would not evolve quickly. Since that time, evolutionary theorists have documented examples of much more rapid evolutionary change. Now, how would we explain the long periods of relative consistency, with little change in some species that we see in the fossil record?

Lack of genetic mutation

Lack of variation

A species was so well adapted that it did not change

Stabilising selection

My guess is that it would be C because not very much climate change has occurred, but you never know...
