Answer:
B. The two species share many proteins in common, and the nucleotide sequences that code for these proteins are almost identical
Explanation:
When two different species have the similar structure, (trait, behavior) these traits can arise through either of two processes:
- The structure is from the common ancestor that gave rise to the two species and that structures are then known as homologous structures. The species with homologous structures are more closely related to each other.
- The structures could have developed independently as a result of convergent evolution (trait was not present in the ancestor), and those structures are then called analogous structures.
