Question

Adaptive radiation is demonstrated by ____.  
A) the dinosaurs going extinct
B) coelecanths remaining similar over hundreds of millions of years
C) the evolution of mammals after dinosaurs went extinct
D) rats and resistance to warfarin
E) warbler body mass and survival

Accepted Answer

Adaptive radiation refers to the process where a single ancestral species gives rise to a number of different species, each adapted to a specific environment or ecological niche. After the extinction of the dinosaurs, mammals underwent an adaptive radiation, resulting in the diversification of many different types of mammals. This is an example of adaptive radiation. Therefore, option C is the correct answer.
