Question

Refer to the cladogram shown above. The numbers 1 through 5 represent species that exist today. What’s the most recent common ancestor of species 1 and 4?

Answer 1

Answer:

Species C is the most common ancestor of species 1 and 4.

Answer 2

Answer:

Species C.

Explanation:

In a cladogram, any two species which originate from the same branch of the tree, share common ancestry. As we can see in the diagram, the species 1 and 4 have a common touch base with the branch of tree arising out of species C, therefore both species 1 and 4 have some characteristics common /similar to that of the species C.

Therefore answer is species C
