Which of these is not a principle of natural selection? all living things have differences.
00:06
Individuals with adaptions will survive.
00:10
Organisms produce more offspring when can survive.
00:12
Organisms with unfavorable traits are more likely to survive.
00:16
The answer here is d.
00:18
They are less likely to survive.
00:23
So natural selection has two big requirements.
00:28
It needs heritable variation.
00:35
So that covers a.
00:37
There are differences between individuals, and it needs differential, reproductive success.
00:53
What this means is some individuals have more offspring than others, but survives it outwards and can then reproduce themselves.
01:01
So if we combine these, you have a population where individuals have differences, and these differences are genetic.
01:09
Some of these differences are advantageous...
