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. All apes and monkeys share a more distant relative, which lived about 25 million years ago.

Detailed explanation-2: -Evidence from fossils, proteins and genetic studies indicates that humans and chimpanzees had a common ancestor millions of years ago. Most scientists believe that the ‘human’ family tree (known as the sub-group hominin) split from the chimpanzees and other apes about five to seven million years ago.

Detailed explanation-3: -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-4: -These so-called hominoids-that is, the gibbons, great apes and humans-emerged and diversified during the Miocene epoch, approximately 23 million to 5 million years ago. (The last common ancestor that humans had with chimpanzees lived about 6 million to 7 million years ago.)

Detailed explanation-5: -Living Primates Monkeys, lemurs and apes are our cousins, and we all have evolved from a common ancestor over the last 60 million years. Because primates are related, they are genetically similar.
