Human

A human being, also human or man, is a member of a species of bipedal primates in the family Hominidae (taxonomically Homo sapiens — Latin: "wise human" or "knowing human").[3][4] DNA evidence indicates that modern humans originated in east 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, with large populations inhabiting every continent on Earth except Antarctica. The human population on Earth is greater than 6.7 billion, as of July, 2008.[5] 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] As of the present time, humans are the most advanced forms of known biological life, in terms of intelligence and dominion of the biosphere. 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 environment 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. From: Wikipedia
