You are looking at a phylogy tree below and depicts the relationship between abcd and e.
00:09
So which of the following statement is true? so when we want to find out the species, if they are, which one of them are closely related, we're looking for the most recent common ancestor.
00:32
So let's take a look at all the options.
00:35
A.
00:37
C is more closely related to e than it's to a.
00:42
So first of all, a and c has the common ancestor right here.
00:48
That's where they converge.
00:51
And then let's take a look at c and e.
00:54
C and e converge right here.
00:58
So obviously c has the more recent comment ancestor to a than c to e.
01:09
So you can see it's on the top part of phylogen tree.
01:12
So that means a and c is more related.
01:25
So a is not.
01:29
D and e are equally closely related to a.
01:35
That's option b.
01:38
So let's take a look at the most recent common ancestor.
01:42
A and d converge right here.
01:46
So this is the most recent common ancestor...
