Nope, I am not convinced by genetic mutation. I see the likelihood that random genetic mutation at the same point in history with at least 2 individuals of opposite sex producing a viable change as beyond likelihood.

But thank your for your suggestion.

Only one member of a mating pair needs to have a bit of solar radiation alter a genomic base pair in its semen or ovum for it to communicate to offspring. Some mutations are dominant, and others are recessive. If a dominant one is environnmentally successful, its host gets to reproduce, and it wins a wider representation in the gene pool. Recessive ones can piggyback on the success of the other genes until two of them meet. If the trait produced by those two together is environmentally successful, then THEY get to reproduce and increase their gene pool frequency, too.

You really need to rethink this.
