Human beings, humans or man (Origin 1590–1600; < L homo man; OL hemo earthly being,[3] also Homo sapiens — Latin "wise human" or "knowing human"),[4] are bipedal primates in the family Hominidae.[5][6] DNA evidence indicates that modern humans originated in Africa about 200,000 years ago. Humans have a highly developed brain, capable of abstract reasoning, language, introspection and problem solving. This mental capability, combined with an erect body carriage that frees the forelimbs (arms) for manipulating objects, has allowed humans to make far greater use of tools than any other species. Humans are distributed worldwide, large populations inhabiting every continent on Earth except Antarctica. The human population on Earth is greater than 6.7&_160;billion, as of July, 2008.[7] There is only one extant subspecies, Homo sapiens sapiens. As of 2008, humans are listed as a species of least concern for extinction by the International Union for Conservation of Nature.[2] Like most higher primates, humans are social by nature. Humans are particularly adept at utilizing systems of communication - primarily spoken and written language - for self-expression, the exchange of ideas, and organization. Humans create complex social structures composed of many cooperating and competing groups, from families to nations. Social interactions between humans have established an extremely wide variety of traditions, rituals, ethics, values, social norms, and laws, which together form the basis of human society. Humans have a marked appreciation for beauty and aesthetics, which, combined with the desire for self-expression, has led to cultural innovations such as art, writing, literature and music. Humans are notable for their desire to understand and influence the world around them, seeking to explain and manipulate natural phenomena through philosophy, art, science, mythology and religion. This natural curiosity has led to the development of advanced tools and skills; humans are the only species known to build fires, cook their food, clothe themselves; they also manipulate and develop numerous other technologies. Humans pass down their skills and knowledge to the next generations through education. The scientific study of human evolution encompasses the development of the genus Homo, but usually involves studying other hominids and hominines as well, such as Australopithecus. "Modern humans" are defined as the Homo sapiens species, of which the only extant subspecies is known as Homo sapiens sapiens. Homo sapiens idaltu (roughly translated as "elder wise human"), the other known subspecies, is now extinct.[8] Homo neanderthalensis, which became extinct 30,000 years ago, has sometimes been classified as a subspecies, "Homo sapiens neanderthalensis", but genetic studies now suggest a divergence of the Neanderthal species from Homo sapiens about 500,000 years ago[9]. Similarly, the few specimens of Homo rhodesiensis have also occasionally been classified as a subspecies, but this is not widely accepted. Anatomically modern humans first appear in the fossil record in Africa about 130,000 years ago, although studies of molecular biology give evidence that the approximate time of divergence from the common ancestor of all modern human populations was 200,000 years ago.[10][11][12]
