Question

Humming birds and hawk illustrate

• A. Convergent evolution
• B. Homology
• C. Adaptive radiation
• D. Parallel evolution

Answer 1

Answer: (C)

Adaptive radiation

Development of different functional structures from a common ancestor is called adaptive radiation. Eg: Hummingbird and hawk moth, Darwin's finches, etc. Whereas development of similar functional structures from different ancestors are known as convergent evolution. Eg: wings of insect and bat.

So the correct answer is adaptive radiation.
