Detailed explanation-1: -Later, Darwin concluded that several birds from one species of finch had probably been blown by storm or otherwise separated to each of the islands from one island or from the mainland. The finches had to adapt to their new environments and food sources. They gradually evolved into different species.
Detailed explanation-2: -These birds, although nearly identical in all other ways to mainland finches, had different beaks. Their beaks had adapted to the type of food they ate in order to fill different niches on the Galapagos Islands. Their isolation on the islands over long periods of time made them undergo speciation.
Detailed explanation-3: -Answer: The finches on the Galapagos Islands had different beaks. The beaks of the finches changed over time. The Galapagos finches had a common ancestor.
Detailed explanation-4: -The association between beak size and diet is most obvious when comparing the species that have contrasting morphology, such as the insectivorous small warbler finches (about 8 grams [g]) and the granivorous large ground finch (about 30 g).
