Question

Cladograms are useful tools for understanding evolutionary relationships between species.



Based on the cladogram above, which two species are most closely related?

species C and B

None of the species are closely related.

species E and D

species D and C

Answer 1

I can’t see the cladogram you’re referring to. Please either upload the image or describe the branching order (which species branch from which nodes).

How to tell which two are most closely related:
- Find the most recent common ancestor (the nearest branching point) for any two species.
- The pair that share a node with no other species between them (sister taxa) are the most closely related.

If you upload or describe the tree I’ll pick the correct pair and explain why.
