The existence of humanoids is said to begin in Africa. It is no coincidence that Africa is also the homeland of chimpanzees, Pan troglodytes, and bonobos, Pan paniscus. These are the two closest living relatives of humans, both sharing nearly 99% of the human genome by common descent. While humans are said to have split from chimpanzees around 5-7 million years ago, bonobos split from their chimpanzee cousins ​​around 2 million years ago. Bonobos inhabit only one part of Africa, the Democratic Republic of the Congo, south of the Congo River, unlike chimpanzees, which inhabit all of West and Central Africa, with the remaining populations spread across several countries. Although these two apes were once thought to be the same species, until the early 20th century, there are many differences socially and physically that make bonobos more than a pygmy chimpanzee. With disparities in morphology, behavior, perhaps even emotions and cognition, and is known as the "chimpanzee that makes love, not war", how can this ape be so very different from its notoriously violent cousin Pan, but share the same amount of similar DNA? to Homo sapiens? And what does this mean for studies of human and humanoid behavior in the past? Physiology With a genetic similarity of 99.6% to chimpanzees, the physical appearance of bonobos is very similar to them. The length of their legs, in proportion to their arms, Bonobos' dark faces, pink lips and slimmer stature are just some of the aesthetic differences between them and chimpanzees. Bonobos are known for their bipedalism and upright walk. It is true that chimpanzees can perform bipedalism when necessary, but they do not match the ease and grace of the Bonobo. Because their habitat remains more constant, they perceive shape... middle of paper... more after birth than the common chimpanzee, and unlike sterile, young chimpanzees, bonobos who cannot conceive continue to have sexual relations. activity. Aggression and territoriality Chimpanzees are known for their aggression. Works Cited Balcombe, Jonathan Peter (2011). The Exulting Ark: A Pictorial Tour of Animal Pleasure.
