Humans Homo sapiens are a species of highly intelligent primates. They are the only extant members of the subtribe Hominina and—together with chimpanzeesgorillasand orangutans —are part of the family Hominidae the great apesor hominids.

Humans are terrestrial animalscharacterized by their erect posture and bipedal locomotion ; high manual dexterity and heavy tool use compared to other animals ; open-ended and complex language use compared to other animal communications ; larger, more complex brains than other primates; and highly advanced and organized societies. Several early hominins used fire and occupied much of Eurasia. Early modern humans are thought to have diverged in Africa from an earlier hominin aroundyears ago, with the earliest fossil evidence of Homo sapiens also appearing aroundyears ago in Africa.

Among the key advantages that explain this evolutionary success is the presence of a larger, well-developed brainwhich enables advanced abstract reasoninglanguageproblem solvingsocialityand culture https://amazonia.fiocruz.br/scdp/essay/is-lafayette-a-hidden-ivy/the-doctor-disability-cultural-paper.php social learning. Humans use tools more frequently and effectively than any other animal: they are the only extant species to build fires, cook foodclothe themselves, and create and use numerous other technologies and arts.

Humans uniquely use systems of symbolic communication such as language and art to Questions On The Main Features Of Professions themselves and exchange ideas, as well as to organize themselves into purposeful groups. Humans create complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. Social interactions between humans have established an extremely wide variety of values, [13] social normsand ritualswhich together undergird human society. Curiosity and the human desire to understand and influence the environment and to explain and manipulate phenomena have motivated humanity's development of sciencephilosophymythologyreligionand other fields of knowledge.

Though most of human existence has been sustained by hunting Feqtures gathering in band societies[14] many human societies transitioned to sedentary agriculture approximately 10, years ago, [15] domesticating plants and animals, thus enabling the growth of civilization. These human societies subsequently expanded, establishing various forms of government and culture around the world, and unifying people within regions to form states and empires.

The rapid advancement of scientific and medical understanding in the 19th and 20th centuries permitted the development of more efficient medical tools and healthier lifestyles, resulting in increased lifespans and causing the human population to rise exponentially. Although it can be applied to other members of the genus Homoin common usage the word "human" generally refers to the only Fetures species— Homo sapiens. The definition of H.

Some paleoanthropologists include fossils that others have allocated to different species, while the majority assign only fossils that align anatomically with the species as it exists today. It may also refer to individuals of either sex, though this latter form is less common in contemporary English. The species binomial " Homo sapiens " was coined by Carl Linnaeus in his 18th-century work Systema Naturae. The genus Homo evolved and diverged from other hominins in Africa several million Qusetions ago, after the human clade split from the chimpanzee lineage of the hominids great apes branch of the primates. The closest living relatives of humans are chimpanzees and bonobos genus Pan[32] [33] as well as gorillas genus Gorilla. The splitting date between human and chimpanzee lineages is placed 4—8 million years ago, during the late Miocene Questions On The Main Features Of Professions. The earliest members of Homo evolved around 2.

During the next million years a process of encephalization began, and with the arrival of Homo erectus in the fossil record, cranial capacity had doubled. One population, also sometimes classified as a separate species Homo ergasterstayed in Africa and evolved into Homo sapiens. It is believed that these species were the first to use fire and complex tools.

Featurez the narratives of Questions On The Main Features Of Professions evolution are often contentious, several discoveries since show that human evolution should not be seen more info a simple linear or branched progression, but a mix of related species.

The earliest transitional fossils between H. These descendants of H. Fossils of anatomically modern humans that date from the Middle Paleolithic aboutyears ago include the Omo-Kibish I remains of Ethiopia [46] [47] [48] and the fossils of Herto BouriEthiopia. Earlier remains now classified as early Homo sapienssuch as the Jebel Irhoud remains from Morocco and the Florisbad Skull from South Africa, have been dated to aboutandlink old respectively.

Human evolution is characterized Fearures a number of morphologicaldevelopmentalphysiologicaland behavioral changes that have taken place since the split between the last common ancestor of humans and chimpanzees.

The most significant of these adaptations are 1. The relationship between all these changes is the subject of ongoing debate.]
