Hello everyone, so the given question asks, which of the following provides evidence that vertebrates evolve from a common ancestor? so, to identify common ancestry, what we identify is something which is known as homology.
00:20
Now, this homology means that two organisms have similar kind of structures, but these structures have different kinds of function depending on the environment a given organism grows in.
00:35
So homology can be a lot of ways.
00:37
First is anatomical.
00:39
So anatomical homology means there are similar structures, similar structures, but they have a different kinds of functions.
00:53
So they have different functions.
00:59
So here option a becomes correct.
01:04
Homology can also be homologies in development and embryology.
01:11
So embryology means that the structures in the growing embryo of two organisms are similar...
