Adaptive radiation is an evolutionary activity which creates several new species out of a single specie. Darwin embraces this philosophy that the finches evolve from an ancestral finch by adapting to the different environment.
Answer: Adaptive radiation
Explanation: Darwin's Finches are the best example of adaptive radiation. The Darwin's finches were originally not the fiches but these endemic species adapted specialized feeding behavior.
They were derived from a single ancestor that arrived to the island from South America. These birds had beaks of different sizes and shapes for the eating food.
