Question

Sharks and dolphins are a good example of

• A. Convergent evolution
• B. Divergent evolution
• C. Adaptive radiation
• D. Both B and C

Answer 1

The correct option is A Convergent evolution

Convergent evolution is the type of evolution in which two unrelated groups of organisms develop similar features, mostly as a result of having to adapt to similar habitats. Sharks and dolphins are both adapted to live in the aquatic environment in spite of being unrelated groups (the shark being a fish, and the dolphin being a mammal). As the name indicates, these unrelated organisms “converge” towards similar patterns of evolution.
