So, in order for evolution by natural selection to occur, the following conditions have to be met.
00:05
So the one and two have been stated, but the third one is the question.
00:09
Environmental conditions can do or must allow for what? right? yeah.
00:16
Sorry, that was my daughter.
00:18
Do you have an answer? oh, that's right.
00:21
So first off, natural selection, i know, i'm telling you right now, is not random.
00:31
If it's not random, then what must the environmental conditions do? they must see favor reproduction of individuals with certain traits.
00:47
So what that means is, let's say we have a forest that is predominantly black trees, right? and maybe a couple, very few green trees.
01:06
And let's say we have these bugs that are black bugs.
01:12
Because environmental conditions favor the black trees.
01:19
There are so many more black trees than green...
