Final answer:
Homo erectus differs from Homo habilis in brain size, size, and tool use.
Step-by-step explanation:
Homo erectus differs from Homo habilis in several ways:
- Brain size: Homo erectus had a larger brain, ranging from about 775 to 1,100 cubic centimeters, compared to the brain size of Homo habilis which was about 600 to 750 cubic centimeters.
- Size: Homo erectus was larger in size, reaching heights up to 1.85 meters and weighing up to 65 kilograms, similar to modern humans. In comparison, Homo habilis was smaller in size.
- Tool use: Homo erectus was the first hominin species to use fire, hunt, and have a home base, while Homo habilis was traditionally thought to be the earliest hominin to use stone tools. However, evidence suggests that A. garhi, an australopithecine species, used stone tools before Homo habilis.
