Modern humans ( Homo sapiens , ssp. Homo sapiens sapiens ) are the only extant members of the subtribe Hominina , a branch of the tribe Hominini belonging to the family of great apes. They are characterized by erect posture and bipedal locomotion ; high manual dexterity and heavy tool use compared to other animals; and a general trend toward larger, more complex brains and societies.  
In common usage, the word "human" generally refers to the only extant species of the genus Homo —anatomically and behaviorally modern Homo sapiens.
In scientific terms, the meanings of " hominid " and " hominin " have changed during the recent decades with advances in the discovery and study of the fossil ancestors of modern humans. The previously clear boundary between humans and apes has blurred, resulting in now acknowledging the hominids as encompassing multiple species , and Homo and close relatives since the split from chimpanzees as the only hominins. There is also a distinction between anatomically modern humans and Archaic Homo sapiens , the earliest fossil members of the species.
