Mutation Is A Chance To Make A Leap Forward

Species to converge into one kind

With repeating conspecific cross or agamic reproduction, species converges into one kind. In other words, respective individuals of a species get to look very similar each other. This is because the characteristics of a genetic code get more defined with repetition of crossing with other very similar gene. As for conspecific cross, if all gene information of two individuals are quite same, you can easily imagine that they will create offspring with another quite same genes. This is logically true. Or if those parents have almost same gene, it is very high possibility that they create offspring with another quite same genes with either parent.
With repeating the crosses like above, a species may converge into one kind.

How ecosystem keeps its diversity

So how ecosystem keeps its diversity? The answer is “by error”. During conspecific cross (and xenogeneic cross as well), errors sometimes occur. In those case, gene information of parents isn’t correctly copied to offspring’s one. And those offspring can take a chance to get a new characteristics that their both parents didn’t have. We call it mutation.
If the new characteristics is, by coincidence, strong to the environment, the character will be inherited to its offspring. Some mutations may create new strong species, and other ones may create new weak species that is to perish.
Anyway, mutation possibly makes (boring)  convergence of species leap forward to another new ones.
