Question

sophie says dolphins and sharks look very similar, so they must be related. jake disagrees, saying dna evidence has shown that dolphins and other aquatic mammals are actually more closely related to the ancestors of modern hippos. who is correct using the modern system of classification? sophie is correct because dolphins look more like sharks than like hippos. jake is correct because classification is based on evolutionary relationships. both are correct because traditional and modern classifications can overlap. neither is correct because neither is taking into account both the traditional and modern systems

Explanation:

Modern biological classification is based on evolutionary relationships, which DNA evidence can reveal. Just because dolphins and sharks look similar (convergent evolution) doesn't mean they are closely related. DNA - based evidence shows dolphins are more related to hippo - ancestors.

Answer:

B. Jake is correct because classification is based on evolutionary relationships.
