Question

1. look closely at the taxa of the rat, rabbit, and squirrel. based on their classifications, which two species are most closely related? how do you know? type your answer here.

Explanation:

In biological classification, organisms that share more specific (lower) taxonomic ranks are more closely related. The rat and squirrel share the same Kingdom, Phylum, Class, and Order (Rodentia), while the rabbit belongs to a different Order (Lagomorpha). This means they share a more recent common ancestor than either does with the rabbit.

Answer:

The rat and the squirrel are most closely related. They share the same taxonomic Order (Rodentia), while the rabbit belongs to a different Order (Lagomorpha); sharing a more specific taxonomic rank indicates a closer evolutionary relationship.
