AP BIOLOGY

Detailed explanation-1: -We do share a common ape ancestor with chimpanzees. It lived between 8 and 6 million years ago. But humans and chimpanzees evolved differently from that same ancestor.

Detailed explanation-2: -Human and chimp DNA is so similar because the two species are so closely related. Humans, chimps and bonobos descended from a single ancestor species that lived six or seven million years ago. As humans and chimps gradually evolved from a common ancestor, their DNA, passed from generation to generation, changed too.

Detailed explanation-3: -Chimpanzees are genetically closest to humans, and in fact, chimpanzees share about 98.6% of our DNA. We share more of our DNA with chimpanzees than with monkeys or other groups, or even with other great apes! We also both play, have complex emotions and intelligence, and a very similar physical makeup.

Detailed explanation-4: -Humans share a common ancestor with modern African apes, like gorillas and chimpanzees. Scientists believe this common ancestor existed. 5 to 8 million years ago. Shortly thereafter, the species diverged into two separate lineages.
