Detailed explanation-1: -Darwin’s model of evolution by natural selection allowed him to explain the patterns he had seen during his travels. For instance, if the Galápagos finch species shared a common ancestor, it made sense that they should broadly resemble one another (and mainland finches, who likely shared that common ancestor).
Detailed explanation-2: -1: Darwin’s Finches: Darwin observed that beak shape varies among finch species. He postulated that the beak of an ancestral species had adapted over time to equip the finches to acquire different food sources.
Detailed explanation-3: -At first, Darwin thought that each finch he found was a different species, however, he was wrong. They were actually all the same species of finch that had evolved over time to be very unique!
