Detailed explanation-1: -One species had long toes and one had short toes, but they were alike in most other ways. The table shows what the scientists found. What is the MOST likely reason for these finds? Short-toed lizards evolved from long-toed lizards on the shady side of the canyon.
Detailed explanation-2: -Organisms can be classified according to any number of criteria, including overall similarities, colors, ecological functions, etc. However, it is generally agreed that the most useful way for scientists to organize biological diversity is to group organisms according to shared evolutionary history.
Detailed explanation-3: -Fossils provide evidence of long-term evolutionary changes, documenting the past existence of species that are now extinct.
Detailed explanation-4: -Evidence that land vertebrates descended from fish includes transitional fossils, anatomical similarities among embryos and adult animals, and genetic evidence of common ancestry.
Detailed explanation-5: -Humans, chimpanzees, gorillas, orangutans and their extinct ancestors form a family of organisms known as the Hominidae. Researchers generally agree that among the living animals in this group, humans are most closely related to chimpanzees, judging from comparisons of anatomy and genetics.
