- 22. Multiple ChoiceIn a cladogram, when does a group of organisms branch off?when a new trait evolveswhen an ancestor becomes extinctwhen it is discoveredhen it becomes large enough
- 23. Multiple ChoiceSophie 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

Whales have evolved this structure because it might be useful in the future.
Whales are able to interbreed with other animals that have hips.
Whales have a diet that includes other animals that have this structure.
Whales share a common ancestor with animals that walk on land.
