Near as I can tell, there are about eight or so species to have a truly worldwide population, (i.e., cats, rats, mice, sharks, dogs, humans, roaches and flies).

Are we really the only ones truly evolving still? I know that for evolution to happen, the environment must change but our environment is theirs as well.

What I mean by that is the fact that the only way any of the other species are changing is by how we are making them change. (Cats and dogs by breeding, pests are building up immunity to our poisons.)

Is this so, and if it is why?
