00:01
So we need to fill in the spaces on this paragraph.
00:04
First of all, as darwin sailed around south america, he had the opportunity to compare the patagonian hairs of the grasslands.
00:11
And this is correct.
00:13
So we have the patagonian...
00:17
Patagonian hairs.
00:18
So darwin, coming from england, was familiar with the european rabbits and hairs.
00:26
And when he saw the patagonian hairs on the grasslands, he saw that they were actually quite similar to the hairs he was used to.
00:33
And we go on to the next paragraph and he notices this.
00:36
So we have the hairs again.
00:40
And they have the long legs and the ears and the movement.
00:43
And he wonders if it's because of their similar environments, leading to convergent evolution.
00:52
And we now know that this is very common in evolution, where if you have the similar environments, you get similar traits to cope with those environments.
01:01
He then saw rears, so a type of bird, at different latitudes.
01:09
So he saw these birds in different latitudes, and he thought the differences in long -in not longitudes, but environments could modify them.
01:19
So this is kind of the opposite of the hairs, and i will throw something to demonstrate.
01:28
So we have our earth, and darwin, actually i'm marked the equator, darwin was coming from the northern hemisphere, and he first travelled over here, and he noticed that at a similar latitude to where he came from, the patagonian hares resembled england's rabbits.
01:51
So the longitude was different...
