Organisms DO NOT evolve to adapt to a given environment. The environment acts
differentially on a population of organisms, "weeding out" those who are least
able to reproduce in that environment.

You just _don't_get_it_, do you? A "species" (which is not a thing like a tree,
but an idea like government) does *not* select ANYthing. INDIVIDUALS live or
die (and reproduce) as chance and fitness dictate. We call the differential
selection by the environment of "fitter" genotypes selection.
