save for one thing. the biggest obsticle to a new line, is the choising of a mate. if food and lack of preditors does not create the pressure to change, the mating cycle will remain the same. this means that if there is nothing that will give a new line an advantage, say in numbers of male survivors to reach the female when she is laying eggs ect, then there has to be something that enables them to reach the female faster or catch her attension faster depending on how that species makes the choise. the old proven species would normally have the advantage, unless the new one gains some new form of advantage. in the wild, the old one cant compete for food, as well so there is more of the new one than the old one that can mate. or the new one would have to be faster at reaching the female, or it would have to be able to attract her better. on the other hand if it were the female that had changed, she would have to attract the males over the other females better.
the simpler the organism, the faster it lives and the slower it changes, due to having fewer things to change.
