evolution = things change, no one can argue that, the average man is more than 3 inches taller than 200 years ago. Also look at how people adapted to thier surroundings when everyone was isolated for thousands of years. Which brings up the question. if a fish changes a little to become better fitted to thier enviroment, should a 5'2" asian guy be considered a different species from a 7'4" black guy? They in some ways are more different than similar animals that humans consider a different species.
