Please show me an experiment which proves that one species can become another entirely. I mean you claim mutations. Ok great, show me something mutating from one thing into another entirely and keeping that mutated form through reproduction. Should be easy right? I mean it happens all of the time obviously since there's billions of different species. With so many different species you would think that it would be as easy as baking a cake.

Took 2 months in the lab to evolve a multicellular organism from a single cell organism.

Life has attempted to minimize mutation rate through accurate DNA replication and DNA repair mechanisms, but accurately copying 3 billion bases at the required rate (once per cell division) is quite difficult. Human beings mutate at a rate of ~1.1 x10^-8 mutations per base per generation. Most of these mutations occur in noncoding regions which are more easily tolerated.

Mutation is mostly neutral and occasionally deleterious to the individual. Rarely, however, mutations provide an adaptive advantage, and this benefits the population as a whole as environment and selective pressures change.
