Homo Habilis

Homo habilis is an extinct species of the Homo genus that lived approximately 2.4 million to 1.4 million years ago in the Early Pleistocene period. The name "homo habilis" means "handy man," reflecting the tool-making abilities of this species.

Physical Characteristics

• Brain size: Smaller than modern humans, with an average brain capacity of about 600 to 750 cubic centimeters.
• Body size: Shorter and smaller than modern humans, with an average height of about 3.5 to 4.5 feet.
• Tool use: Homo habilis is known for its use of tools, particularly the Oldowan tools, which were simple stone implements used for cutting and scraping.

Habitat and Behavior

Homo habilis is believed to have lived in sub-Saharan Africa, primarily in savannah environments. They were likely scavengers and hunters, using their tool-making abilities to process meat and gather plant foods. Their ability to make and use tools represented a significant step in human evolution.
