But just because one mutation is helpful to a species, does not mean that the parent set of genes is harmful and will die out.

For instance, humans with hanging earlobes came from the same common ancestor as humans with attached earlobes. One could ask, "But why did only some of the humans mutate, but not the others?". Well, at this point in time, ear lobes don't really have much to do with the survival of our genes. However, if for some reason, women become sexually attracted only to men with attached earlobes, then those men will reproduce at a rate faster than those with hanging earlobes, and the attached earlobe genes will prevail.

Wow I'm writing a lot. But the point is, just because certain animals encounter mutations that nature(or the other sex for that matter) deems desireable, doesn't mean that all examples of the species that do not have that gene are going to die out.

I personally believe that we all got to be via the cyclic model of the universe, panspermia, natural selection, and evolution. But that's just me.
Haha, ours is pretty similar. Pretty much all these were posted while I was writing that it took me a while lol.
