What makes humans apes

Humans are classified as mammals and as primates. Both humans and apes belong to a group of primates known as the Hominoidea. As hominoids, humans and apes exhibit a range of similarities, including complex social relationships, large brains, and the capability to utilize tools.

Evidence indicates that in the past 2 million years, individuals belonging to the genus Homo experienced significant evolutionary developments. The increasingly complex patterns that resulted served as the foundation of the human niche. A niche consists of the ecosystem an organism inhabits and all of the organism's interactions within that space. Processes occurring within this niche, including the use of fire and new modes of teaching and learning, offered humans greater control over the surrounding environment.

Fuentes, in fact, proposes that the most distinctive feature of humanity is its ability to significantly alter ecosystems. Fuentes applies anthropological theory to emphasize the highly significant role humans play in determining the collective future of life on the planet. This collaborative and imaginative capacity for creativity also drove the development of religious beliefs and ethical systems, and even the production of artwork. Such capacities fueled and facilitated our ability to compete in more deadly ways.

We hear it all he time: Humans are primates. But what does that really mean? What do we have in common with a baboon? Or a creepy aye-aye? Or even our closest living relative, the chimpanzee? These are simple questions to answer from a genetic perspective—humans share more DNA with lemurs, monkeys and apes than they do with other mammals. Genetic research of the last few decades suggests that humans and all living primates evolved from a common ancestor that split from the rest of the mammals at least 65 million years ago.

But even before DNA analyses, scientists knew humans belong in the primate order. Carl Linnaeus classified humans with monkeys, apes and other primates in his 18th-century taxonomic system. Even the ancient Greeks recognized similarities between people and primates. 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.

A comparison of DNA nucleotide sequences of living primate species show that humans are most closely related to the African apes. Next in descending order of genetic closeness to us come the Asian apes, Old World monkeys, New World monkeys, tarsiers, and finally the lemurs and lorises.

This genetic comparison corresponds exactly with a comparison of homologous primate physical traits. It also fits nicely with what we know from the fossil record. The prosimians were the first to evolve.

Next came the monkeys, then the apes, and finally humans. NOTE : A draft of the rhesus macaque monkey complete genome was completed in Comparing this genome with those already established for chimpanzees and modern humans will provide an even better tool for understanding the similarities and differences between the major groups of primates.

This somewhat lower percentage for macaques is to be expected because the last common ancestor of macaques and humans was about 19 million years ago, while the chimpanzees and human evolutionary lines diverged only around million years ago.
