Humans share the vast majority of their cognitive skills with other great apes. In addition understanding of social behavior and relationships to understand. Congratulations: You are an ape. A "great ape," technically. Alongside us in this brainy family of animals are four other living species. i.e., man, the great apes, and the Hylo- RELATIONSHIPS BETWEEN MAN AND APES TABLE 1. Species .. different from the human one, a difference.
Physical description[ edit ] The great apes are large, tailless primates, with the smallest living species being the bonobo at 30—40 kilograms in weight, and the largest being the eastern gorillas, with males weighing — kilograms. In all great apes, the males are, on average, larger and stronger than the females, although the degree of sexual dimorphism varies greatly among species. Although most living species are predominantly quadrupedalthey are all able to use their hands for gathering food or nesting materials, and, in some cases, for tool use.
Hominidae - Wikipedia
Chimpanzees and orangutans primarily eat fruit. When gorillas run short of fruit at certain times of the year or in certain regions, they resort to eating shoots and leaves, often of bambooa type of grass. Gorillas have extreme adaptations for chewing and digesting such low-quality forage, but they still prefer fruit when it is available, often going miles out of their way to find especially preferred fruits. Humans, since the neolithic revolutionconsume mostly cereals and other starchy foods, including increasingly highly processed foodsas well as many other domesticated plants including fruits and meat.
Hominid teeth are similar to those of the Old World monkeys and gibbonsalthough they are especially large in gorillas. The dental formula is 2.
Human teeth and jaws are markedly smaller for their size than those of other apes, which may be an adaptation to eating cooked food since the end of the Pleistocene. The young are born helpless, and require care for long periods of time.
Compared with most other mammals, great apes have a remarkably long adolescence, not being weaned for several years, and not becoming fully mature for eight to thirteen years in most species longer in humans.
Geneticists have come up with a variety of ways of calculating the percentages, which give different impressions about how similar chimpanzees and humans are. A comparison of the entire genome, however, indicates that segments of DNA have also been deleted, duplicated over and over, or inserted from one part of the genome into another.
No matter how the calculation is done, the big point still holds: From the perspective of this powerful test of biological kinship, humans are not only related to the great apes — we are one. The DNA evidence leaves us with one of the greatest surprises in biology: The human evolutionary tree is embedded within the great apes.
The Gap Between Humans and Apes
The strong similarities between humans and the African great apes led Charles Darwin in to predict that Africa was the likely place where the human lineage branched off from other animals — that is, the place where the common ancestor of chimpanzees, humans, and gorillas once lived.
The DNA evidence shows an amazing confirmation of this daring prediction. The African great apes, including humans, have a closer kinship bond with one another than the African apes have with orangutans or other primates. The DNA evidence informs this conclusion, and the fossils do, too. Even though Europe and Asia were scoured for early human fossils long before Africa was even thought of, ongoing fossil discoveries confirm that the first 4 million years or so of human evolutionary history took place exclusively on the African continent.
It is there that the search continues for fossils at or near the branching point of the chimpanzee and human lineages from our last common ancestor.

Primate Family Tree Due to billions of years of evolution, humans share genes with all living organisms. The percentage of genes or DNA that organisms share records their similarities. We share more genes with organisms that are more closely related to us. Humans belong to the biological group known as Primates, and are classified with the great apes, one of the major groups of the primate evolutionary tree.
