Final answer:
H. erectus findings from Olduvai Gorge include evidence of stone tool use, the harnessing of fire, a larger brain size, and physical features more akin to modern humans.
Step-by-step explanation:
H. erectus findings from Olduvai Gorge in Tanzania include evidence that this species had developed and used stone tools, evidenced by the Acheulean industry, and the utilization of fire. The fossils found in Olduvai Gorge also suggest that H. erectus had a larger brain size compared to earlier hominins, with a cranial capacity of 775 to 1,100 cubic centimeters. Additionally, H. erectus was more similar in physical stature to modern humans, with reduced sexual dimorphism, a chance for heights up to 1.85 meters, and weights up to 65 kilograms.
