Alright, so this question asks, where on a phylogenic tree would you find the most recently evolved organism? so basically how a phylogenic tree is constructed.
00:12
So this part right here, which i have drawn, is the base.
00:17
So this part right over here, right over here, this is the base.
00:26
And now what a phylogenic tree does is it basically splits off where an ancestor has divided into two, separate species.
00:35
So say that this ancestor splits off over here into species a and species b.
00:45
And this right here, where it splits off, this is called a node.
00:52
This entire thing is a branch.
00:54
And the longer the branch is, the longer that species has been in existence...
