The chimpanzee has more genes in common with the mountain gorilla than with the baboon.
00:05
Which of these explains her? a, the baboons evolved from chimps, not gorillas.
00:11
Chimps and gorillas share a more recent common ancestor than chimps and baboons.
00:17
Gorillars evolve from chimps, not from baboons, or convergent evolution led to the genetic similarities.
00:25
First, we need to talk about what means to be evolved from another.
00:30
So chimps, gorillas and baboons are all modern organisms.
00:35
One is not descended from another.
00:38
They can share a common ancestor, and they do share common ancestry, but one is not evolved from the other.
00:44
So it can't be a or c.
00:45
The same way that we can't say humans are evolved from chimps.
00:49
We have evolved from a primate ancestor that had a lot in common with the chimps, and the chimps also are descended from their ancestor...
