Question

How did speciation in Darwin’s finches occur?

A. Adaptive Radiation
B. Convergent Evolution
C. Interbreeding
D. Random mating

Answer 1

Answer: Adaptive radiation

Step-by-step 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.

Answer 2

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.
