Probably it will, this is what I am trying to say. These combinations probably can appear, but they are "short lived".

But as stated by Darwin evolution is really survival of the fittest, the strongest. By trial and error, this can be achieved through the process of mutation. Therefore, the gene that survived are necessarily the strongest gene. For the Earth environment not necessarily in other planetary environment but I doubt the optimization objective function varies widely.

That is all truth; all this happened on Earth, but these mutations are very interesting. For example, if there were a near - supernova explosion, radiation might be so intense, that mutations would be really horrible, and maybe none of them would be useful.
What I really want to say is that our evolution has gone all the way from amino acids to the humans. But in most cases, I think this cant happen - environment is either too stable or too disturbing, the planets moon is to small so it cant make planets rotation stable - climatic changes are drastic, it hasn’t got any gas giants (like Jupiter) in the outer regions of the system, so planet is exposed to the asteroids impacts...etc. This could all lead to the blind roads of evolution, but since these roads are blind, there will never be a "observer" in this evolution, to witness it. By witness I mean humans.

Our evolution is too perfect to me; I believe there are other possibilities.
Like the Multi-verse theory proposes almost unlimited number of potential "constants of the universe" I think that it may be plausible to think there are other evolutions possible. Note that I am implying these evolutions toward other planets, not on Earth.

What do you think?
