The question asks to identify the hominin species typically considered the 'first real human'. This designation is often linked to the earliest members of the genus Homo, distinguished by significant advancements like consistent tool use.

Homo Habilis: Early Human Ancestor

Homo habilis, meaning "handy man", is widely regarded by paleoanthropologists as one of the earliest species within the genus Homo. Its discovery was significant because it was found alongside primitive stone tools (Oldowan tools), suggesting a more advanced cognitive ability and behavior compared to earlier hominins.

• Lived approximately 2.4 to 1.4 million years ago.
• Associated with the earliest known stone tool manufacture.
• Showed a slightly larger brain capacity than Australopithecines.

Distinguishing Habilis from Other Hominins

The classification of Homo habilis as the 'first real human' separates it from earlier ancestors and later, more derived species:

• Australopithecus: These earlier hominins (like Lucy's species) predated Homo habilis and, while bipedal, lacked the clear evidence of sophisticated tool-making that defines early Homo.
• Homo erectus: This species emerged later than Homo habilis and possessed a larger brain, more advanced tools (Acheulean), and migrated out of Africa. They represent a more evolved stage.
• Homo sapiens: These are anatomically modern humans, who evolved much more recently (around 300,000 years ago) and possess significantly larger brains and complex culture.

Therefore, Homo habilis is often cited as the 'first real human' due to its position as the earliest known member of our genus, marked by the crucial development of tool use.
