Detailed explanation-1: -Which of the following statements provides the best scientific evidence that chimpanzees and rhesus monkeys come from a common ancestor? They have similar genetic sequences. Fossil evidence shows that ancient aquatic reptiles called ichthyosaurs looked very similar to modern dolphins.

Detailed explanation-2: -species change through time. What type of evidence for evolution would arise from a comparison of the DNA sequence of humans and monkeys? DNA base sequences and amino acid sequences of proteins are compared in biochemical evidence for evolution.

Detailed explanation-3: -Which of the following statements best explains the claim that different finch species originated from a single ancestral species? The finch populations exhibited different desirable traits as a result of adapting to different environmental pressures.

Detailed explanation-4: -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.

Detailed explanation-5: -DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are. Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
