Detailed explanation-1: -There are now at least 13 species of finches on the Galapagos Islands, each filling a different niche on different islands. All of them evolved from one ancestral species, which colonized the islands only a few million years ago.

Detailed explanation-2: -Adaptive radiation is also known as adaptive divergence. Adaptive radiation is when closely related organisms rapidly accumulate differences as they specialize to fill certain ecological niches.

Detailed explanation-3: -One of the most common examples of adaptive radiation is that of Darwin’s finches which he found on Galapagos islands. He observed a variety of birds on the island, all of which were formed from a single seed-eating species which landed there accidentally.

Detailed explanation-4: -Today, Darwin’s finches are the classic example of adaptive radiation, the evolution of groups of plants or animals into different species adapted to specific ecological niches.
