Why Are There Still Monkeys?
From SkepticWiki
[edit] Definition
Creationists are fond of asking "If men are descended from monkeys, why are there still monkeys?" This is presumably intended as a rhetorical question, as we have seen no evidence that anyone asking it has ever seriously tried to find out the answer.
[edit] Discussion
One might as well ask "If Iceland was colonized by Scandinavians, why are there still Scandinavians?" It is clear that expansion from one environmental niche into another does not make the former uninhabitable.
In the same way, when one lineage of monkeys gradually changed from arboreal to ground-dwelling habits, and evolved into apes, this did nothing to prevent other lineages of monkeys from continuing to inhabit the tree tops.
Humans in particular are not in competition with monkeys: if you will try the experiment, the last thing you'll realize before you die of a broken neck is that Homo sapiens is singularly unsuited to a life spent leaping from tree to tree in the rainforest canopy.
