Question

1. which species does rexoraptor most likely share a recent common ancestor with?

a. lizard
b. opossum
c. robin
d. shark

Explanation:

To determine the species Rexoraptor (a dinosaur - like name, likely a reptile - related species) shares a recent common ancestor with, we analyze the groups: Lizard is a reptile, Opossum is a mammal, Robin is a bird, and Shark is a fish. Reptiles (like dinosaurs) and lizards are in the same broader group (reptilian lineage) compared to the others. So Rexoraptor (as a reptile - like species) is most likely to share a recent common ancestor with Lizard.

Answer:

A. Lizard
