Question

While on the Galápagos Islands Darwin noticed that three were a number of species of finches that he theorized defended from a common ancestor he hypothesized that these finches became isolated on an island and adapted to fit an ecological role on that island what about the finches led Darwin to. This belief ?

Answer 1

The different types of beaks on the finches 

Answer 2

The finches had undergone an evolution through natural selection due to the adaptation to the environment in which they lived.

Step-by-step explanation:

Darwin studied the finches found on the Galapagos Islands extensively.

He discovered that there were several species of finches that differed by the shape of their beak, this differentiation was based on the feeding of each finch, for example, those who ate fruits in the middle of the cactus had the most elongated beak and those who ate from the ground they had a more flat peak.

Darwin could verify that there was an ancestor of the finches from which all these different species that changed their morphology had evolved through natural selection depending on the adaptation to the environment.
