True or False. Natural Selection can cause an individual to change in its lifetime

Sailor:

This statement is true. Natural selection is the process of organisms adapting to changes in nature in order to survive.

SmokeyBrown:

Natural selection does allow organisms to adapt, but these changes take place over very long periods of time--much more than a single lifetime In fact, the mechanism behind natural selection is based on organisms passing on "favorable" genes to future generations, which means natural selection does not occur over the course of an individual's lifetime but rather along a genetic lineage

SmokeyBrown:

It looks like I'm being outvoted, but I still maintain that the statement in the question is False, for reasons I mentioned above--natural selection occurs across populations of organisms, not in individuals; the changes also take many generations, much longer than a single lifetime
