Hello everybody.
00:01
Today i'm going to be walking you through question number six from chapter 51 of the campbell biology textbook.
00:12
The question reads, which of the following is not required for a behavioral traits to be passed to or to evolve by now? natural selection.
00:37
And what is natural selection? natural selection is the innate pressure that causes better adapted animals to survive and less adapted or less well adapted animals to die out.
01:04
And this happened with animals and this happens behaviors.
01:10
All right.
01:12
So a, the behavior is entirely genetic.
01:27
Also, i'll be paraphrasing these answer choices, just as has them.
01:32
B, behavior varies among individuals, c, and reproductive, productive success is dependent in part on the behavior.
02:00
Or d, some part of the behavior is genetic.
02:08
All right, so let's go through each of the following answer choices.
02:14
So starting with d, some part of the behavior is genetic.
02:18
Well, yes, that would make sense because that's how a lot of behaviors are passed down through genes.
02:27
So some part of the behavior is genetic...
