Okay, so if you look at the three phallological genetic tree, which one showed similar relationship? so after i evaluate the answer, the correct answer is b and c.
00:13
So this is because you can see that each species, they diverge, and between diverge, you have branch points.
00:20
And those branch points, it looks like fork.
00:23
You can actually rotate it 180 degrees, and then they're still the same relationship.
00:29
Shape so for example the if you rotate this one this branch all the way to um 180 degrees now the a is going to be underneath instead of up there so this look exactly like what we have in c here because you know you see now the branch the a is all the way down to the bottom but the rest of them keep the same shape.
01:03
You still have this branch, the same branch point here, and it branch out to form b.
01:21
So you can see a and b still have the same two branch point difference.
01:28
So you just flip it 180 degrees down from top to bottom, so you still have the same two.
01:36
And then you can see that another one that is being flipped is going to be c.
01:44
So c was originally here.
01:48
Again, it was flipped up.
01:50
So you can see that if you twist the entire fork up, now the c is above d now.
02:03
Then after the flip, it will be underneath...
