You're living in a dream world. The only place where "populations and taxa" is happenig is with the government where they tax the population. If you think it is myth, then don't file your taxes for 2006 and pretend that it is all myth.
I can refuse to file my taxes for 2006 and I will get into trouble because it is fact and real. I can however, refuse to believe in evolution and nothing will happen because it is rooted in myth!
