Final answer:
Humans and chimpanzees share a high percentage of identical DNA, over 98%. However, they have undergone divergent evolution, resulting in distinct physical and behavioral differences.
Step-by-step explanation:
Humans and chimpanzees share a high percentage of identical DNA, over 98%. This genetic similarity suggests a common ancestor. However, humans and chimpanzees have undergone divergent evolution, leading to distinct physical and behavioral differences. Humans have a larger, more complex brain, giving us greater cognitive abilities and technological advancements. Additionally, humans have unique qualities such as bipedalism, increased brain size, and opposable thumbs.
