[quote]1) This is the definition of a species. 2) This is why natural selection happens. 3) Mutations are not "often lethal". The vast majority are insignificant. Many times a significant mutation can be helpful or harmful depending on external factors 4) Mutation adds the variety. Natural selection determined which traits stay.[/quote] So if you go all the way back to my original point with the other fella, I stated that mutations was the only thing that can change an animal to another. (I stand by that natural selection cannot create new info only select from what it in place.

  • It's not the only mechanism of evolution, though. If mutation existed without natural selection, evolution could not take place. They work hand in hand.

I believe if someone could prove the rate of positive mutations that are both beneficial and passed on they would learn that there has not been close to enough time to have all the variations we see of life on this planet. Even if this earth is 4.6 billion years old. I think they are saying it is even older now.
