Okay, so for this question, we're going to address the idea of natural selection.
00:07
And then we'll be discussing how that relates to a behavioral trait.
00:18
So let's just go back to this idea of natural selection by really starting with darwin and wallace.
00:27
And natural selection is going to be that there's going to be certain traits or adaptations in individuals.
00:38
Certain traits with these adaptations in individuals that allow them to survive and reproduce maybe more than other individuals without these traits.
01:29
So our first thing here is that the idea that we just said certain traits, adaptations, some others.
01:43
So we have variation among individuals where some of them have the trait, some of them don't.
01:58
We see that there is differing reproductive success, so many more offspring are produced based on that trait.
02:19
And then in general, there is inheritance of those traits from the parent to the offspring.
02:36
So most of this holds true when we're talking about behavioral traits, and that's what we're referring to in this question.
02:49
And so which of the following is not a requirement for behavioral traits? we're going to eliminate b because we said the behavior varies among individuals that is required.
03:13
So variation happens among individuals...
