Natural selection: If a change has benefit, then it will be kept.
A implies B.
"If something like that happened" (was kept).
"Then it would mean it had benefit."
B, therefore A.
This is just affirming the consequent.
<edit>
This is a common way of slipping in an assumption (something like that happened - B) and hiding it within an accepted implication (natural selection - A implies B).
At its root, it's just begging the question.
