Question

In the space below, write the number of the tree diagram that shows the most probable evolutionary relationship between the three species. Support your answer.

Answer 1

The correct tree is the 2nd tree :)

Answer 2

Basically, what you want to know is : how similar are the Species?

If you look at Species A and B - all of their enzymes are different! so they're not very similar.

Species A and C have all the same enzymes, so A and C are related and B is less related to them. Tree 2 is the correct tree.
