Emergence of new species

All species have a chance to evolve into new species. Not because there is a function built for evolving stories. This evolution happens instead by random mutations to the genetics of each individual organism being born.
What we see as species is simply a generalization of each organism's genes, a generalization shared by organisms whose genetics are close enough.
What mutations do, in terms of creating new species, is making the generalization of an organism's genetics no longer match any other species that has been previously identified.
The organism will of course also be different than others, simply because its genetics are different. The ways it is different is all based on what genetic markers that have been mutated, and by how much.
Again, species as a concept is only something we, as observers, apply as a label to to an organism to be able to find name it, and to have a set of expectations of or behavior. While to physics, we are all simply organisms with a vast array of genetic compositions.
This, is also how the evolution simulation works.
