Is this a report of an actual experiment or is it conjecture? Changing surface
characteristics of organisms is hardly evolution. Animal breeders do it all
the time. Can you conceive of a similar scenario in which a fruit fly becomes a
house fly, a horse fly or a dragon fly? That would be evolution.
