Show me a genetic change from one species to another. That is the core belief that one species can give birth to a new improved species. Show me one species that you can definitively show transformation through natural genetic mutation. Science has yet to find an observable link between 2 species as such. Currently, all "links" are not substantiated by genetics. They have yet to show that a naturally occuring genetic mutation improves a species, and can be passed on to future offspring, to the point of creating a new species.
