Human Evolution 10 Picture

Homo sapiens are the only living species in the Homo genus of bipedal primates in Hominidae, the great ape family. Anatomically modern humans originated in Africa about 200,000 years ago, reaching full behavioral modernity around 50,000 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 hands for manipulating objects, has allowed humans to make far greater use of tools than any other living species on Earth. Like most higher primates, humans are social animals. Humans are noted for their desire to understand and influence their environment, seeking to explain and manipulate phenomena through science, philosophy, mythology, and religion. This natural curiosity has led to the development of advanced tools and skills, which are passed down culturally; humans are the only species known to build fires, cook their food, clothe themselves, and use numerous other technologies. The study of humans is the scientific discipline of anthropology.

Normally, there is no sudden discontinuity where you can say one species ends and another begins in the history of life. Any such boundaries are randomly placed along a continuity of change through the ancestral forms to the present day. Indeed, that organism looking back at you in the mirror is transitional. It's an intermediate between the ancestors of modern humans and whatever our distant descendents become (assuming we survive to leave any).
