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.
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.
