hair

1. which organism is most related to the rodents and rabbits on this cladogram?

Explanation:

Question 8

To determine what separates rabbits/primates from crocodiles, we analyze the cladogram. The trait "Hair" is a synapomorphy (shared derived character) for the group containing primates, rodents & rabbits. Crocodiles do not have hair, while primates and rodents/rabbits do. So the trait that separates them is hair.

In a cladogram, organisms that share a more recent common ancestor are more related. Primates share the same branch (and the "Hair" trait) with rodents and rabbits, meaning they have a more recent common ancestor compared to other organisms like crocodiles, birds, etc. So primates are most related to rodents and rabbits.

Answer:

Hair
