Homo habilis is an early human species that lived approximately 2.4 to 1.4 million years ago. It is considered one of the first members of the genus Homo and is known for its ability to use tools. Fossils of Homo habilis were discovered in East Africa, particularly in sites like Olduvai Gorge, indicating its role in early human evolution. This species had a smaller brain size compared to later humans, averaging around 510 to 600 cubic centimeters. Homo habilis exhibited a mix of ape-like and human-like features, including a more rounded skull and smaller teeth, suggesting a shift towards a more omnivorous diet.
