Detailed explanation-1: -From this one migrant species would come many–at least 13 species of finch evolving from the single ancestor. This process in which one species gives rise to multiple species that exploit different niches is called adaptive radiation.

Detailed explanation-2: -Darwin’s finches are a classic example of adaptive radiation. The ecological diversity of the Galápagos in part explains that radiation, but the fact that other founder species did not radiate suggests that other factors are also important.

Detailed explanation-3: -Four of the 14 finch species found in the Galápagos Archipelago, which are thought to have evolved via an adaptive radiation that diversified their beak shapes, enabling them to exploit different food sources.

Detailed explanation-4: -The phenomenon of adaptive radiation was first observed by Darwin when he travelled to a place called Galapagos Island. There he observed that there were finches with different types of beaks. So, he concluded that all of these inches radiated on the same island from a single ancestor Finch.

Detailed explanation-5: -The Galápagos finches are a classic example of adaptive radiation. Their common ancestor arrived on the islands a few million years ago. Since then, a single species has evolved into different species that are adapted to fill different lifestyles.
