Why do chimps have forward facing eyes?

Humans and chimps both have forward-facing eyes. This is because they are both primates and share a common ancestor. Primates are a group of mammals that includes humans, chimpanzees, gorillas, orangutans, and monkeys. All primates have forward-facing eyes, which gives them a wide range of vision and helps them to focus on objects near and far away.

Forward-facing eyes are an important adaptation for primates, who are arboreal animals that live in trees. This adaptation allows them to easily see their surroundings and to navigate through the trees. Primates also use their forward-facing eyes for social interactions, such as facial expressions and eye contact.
