Hi there.
00:03
This question is about some of darwin's observations and thoughts as he was developing his theory of evolution.
00:16
All right.
00:17
So let's look at which one of these is correct.
00:19
Let's look at letter a first of all.
00:22
Letter a says members of a population show little variation in their inherited traits.
00:27
Well, that's false.
00:28
He did not say that and that is not true.
00:31
If you just look around you, you see lots of variation in just the populations around you, be it people or dogs or cats or plants.
00:42
There's lots of variation.
00:45
Okay, letter b.
00:47
So letter a is not our answer because that is false.
00:51
Letter b, individuals whose inherited traits give them a higher probability of surviving and reproducing tend to leave more offspring.
01:02
Ah, well, that's true.
01:04
If these individuals have a higher chance of survival, then they are going to be able to reproduce and leave more offspring.
01:13
If they were to die before they were able to reproduce, they wouldn't leave any offspring...
