By looking at the phylogenetic tree, we can tell which taxonomic groups are more closely related to each other or less related. In this phylogenetic tree, primates and rodents/rabbits is the pair most closely related.

The phylogenetic tree is composed of,

Lineages → The taxonomic groups of interest. These are placed in the extremes of the branches. Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor. Root → This is the older common ancestor that all lineages share. The first one in the tree.

⇒ Highly related groups that share a recent common ancestor. This means that they all diverge from the same node.

⇒ Lineages less related to each other are those whose common ancestor is far away in history.

In the exposed pylogenetic tree, there are two groups of linages that are closely related to each other.

Group 1 ⇒ Primates and rodents/rabbitsGroup 2 ⇒ Reptiles and birds

These two groups share a common ancestor farther away, which is the point from where each group diverge.

Among the given options, we have

A) Sharks and ray-finned fishes ⇒ Not closely related

B) Amphibians and primates ⇒ Not closely related

C) Primates and rodents/rabbits ⇒ CLOSELY RELATED

D) Rodents/rabbits and birds ⇒ Not closely related
