[Charles H. (The_r0nin)]

Selection pressures don't have to exist (e.g. in a zoo).

What?! No selection pressure in a zoo? No animal is exposed to other than normal behaviors or normal environments in a zoo? Wide-ranging animals, highly territorial animals, stress-sensitive animals don't face selection pressures in zoos? What planet do you live on?
