Best Answer - Chosen by Asker:

Human beings, or humans (Homo sapiens — Latin: "wise human" or "knowing human"[2]) are bipedal primates in the family Hominidae!.[3][4] DNA evidence indicates that modern humans originated in Africa about 250,000 years ago!. Humans have a highly developed brain, capable of abstract reasoning, language, introspection, and emotion!. 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 now permanently inhabit every continent on Earth, except Antarctica (although several governments maintain permanently- and seasonally-staffed research stations there)!. Humans also now have a continuous presence in low Earth orbit, occupying the International Space Station!. The human population on Earth amounts to over 6!.7 billion, as of July, 2008!.[5]

Like most primates, humans are social by nature!. However, they are particularly adept at utilizing systems of communication for self-expression, exchanging 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 innovations such as culture, art, 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 science, philosophy, mythology and religion!. This natural curiosity has led to the development of advanced tools and skills; humans are the only currently known species known to build fires, cook their food, clothe themselves, and manipulate and develop numerous other technologies!. Humans pass down their skills and knowledge to the next generations through education!.Www@QuestionHome@Com
