Evolution: Abrupt Changes

[robvalue]

It makes sense to me. A species is always naturally tending towards the most efficient form for the environment (although a good degree of junk tends to sneak through the net along with it). So if there's a big change in the environment, there going to be a big gap between the current norm for the species and the new optimum characteristics. Useful changes are going to be more important and so will get factored in faster.

If the environment doesn't change or changes only slightly, the norm won't be very far away from optimum.

Or, y'know, reality is a big lie and it's all done by magicks.
