And you're basing your claims of no evidence on...? I study evolution and genetic variability in populations of a certain algae, and have data from the last 20 years from across the country (not the person who took it 20 years ago though) to say that a population doesn't evolve would be absurd. What about genetic drift? What about species isolation? What about changes in a population that prevent sexual reproduction with the rest of the species? The truth of the matter is, there is a plethora of data supporting evolution.
