Detailed explanation-1: -The Galápagos finches have provided a tremendous amount of information about evolution. DNA sequence similarities are the strongest evidence for evolution from a common ancestor. What is biogeography and what does it provide? Biogeography is the study of how and why plants and animals live where they do.

Detailed explanation-2: -Darwin could compare only the anatomy and embryos of living things. Today, scientists can compare their DNA. Similar DNA sequences are the strongest evidence for evolution from a common ancestor.

Detailed explanation-3: -TRUE Fossils provide clear evidence that evolution has occurred. 2. TRUE Embryos of many different vertebrates look much more similar than the adult organisms.

Detailed explanation-4: -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-5: -Evidence for evolution: anatomy, molecular biology, biogeography, fossils, & direct observation.
