Answer:
The non human primates, esp. the chimps have their genes closely related to human primates. For the physical similarities, their dental formula is similar to ours, the skeletal structural is similar as well, their faces have many muscles to specifically convey an emotion like ours, opposable thumbs to have precision grips in things like needles or small objects, and some of the non-human primates have a tendency to have an erect posture and walk bipedal. I guess the physical differences them having more hair, and tails are longer? i guess one of the examples of us having shared ancestry between close non-human primates are their learned behavior taught to the younger ones. They live in groups which are similar to hunter-gatherers and some individuals may leave a group and join another, the idea of affiliation with a group and altruism to aid others in their group, grooming is seen often to show trustworthiness and reinforces bonding.
