Dental arcade of an early hominids. Toggle Caption The dental arcade is the shape made by the rows of teeth in the upper jaw.
This illustration shows the dental arcade of an early Homo sapien top and Australopithecus africanus bottom. This helps to catapult the body upwards again.

People have much more complex forms of verbal communication than any other primate species. We are the only animal to create and use symbols as a means of communication.
We also have more varied and complex social organizations. The most distinctive feature of humans is our mental ability to create new ideas and complex technologies. This has proven invaluable in the competition for survival. However, the great apes are also surprisingly intelligent, having mental levels equivalent to a year old human child.
This is sufficient to allow them to learn and use the sign language of deaf humans in at least a rudimentary way, but they do not have the capability of producing human speech and language. This is likely due to the fact that they have a different form of another key regulator gene known as FOXP2. There is one additional curious difference between humans and all other primates that is worth noting. O lder human females go through menopause and become sterile , often decades before dying of old age.
Female chimpanzees, gorillas, and other non-human primates usually remain capable of conception and giving birth even when they are very old. In the wild, they live only a relatively short amount of time following menopause, if they go through it at all. One explanation for this difference in humans is that years of life following menopause has proven to have natural selection value for our species. Having raised their own children, post-menopausal women around the world often take care of their grandchildren while their daughters are working.
It is argued that this increases the chances that the grandchildren will survive to adulthood because they receive this additional experienced and caring attention. Grandmothers helping daughters to raise their children also allows mothers to have additional babies before the older ones are mature enough to take care of themselves. All other primates normally do not give birth again before their current child no longer needs parental care.
Review of Ape and Human Classification. Apes and humans are members of the suborder Anthropoidea , the Infraorder Catarrhini , and the s uperfamily Hominoidea. Ceboidea Cercopithecoidea Hominoidea hominoids species: New World monkeys Old World monkeys apes humans The gibbons are sufficiently different to be in their own family of hominoids, the Hylobatidae.
Along with the Great apes , humans are members of the family Hominidae. Of all living species, people are genetically and evolutionarily closest to the African apes. Subsequently, we have been placed into the same subfamily, the Homininae. Hylobatidae Hominidae hominids subfamily: Ponginae Gorillinae Homininae tribe: Panini Hominini hominins species: gibbons orangutans gorillas chimpanzees bonobos humans Evolutionary Relationship of Primates.
