That depends on the resources available, whether the creautre is fully exploiting them and also whether the older creatures are useful in ensuring the survival of the group.bad rider said:For example, a species whos life span is of a great length has little reason to reproduce. This is because it would strain the resources of their natural environment and result in mass death as a result of starvation/overpopulation. Whereas a species that has a short life span is encouraged to reproduce to be able to maintain their environment.
Short lived creatures evolve faster because each generation takes less time to produce the next.
