Final answer:

East African H. erectus have thinner walls of the braincase while Asian H. erectus have thicker walls, indicating differences in the anatomy possibly due to adaptations to their environments.

Step-by-step explanation:

East African H. erectus have thinner walls of the braincase and Asian H. erectus have thicker walls of the braincase. This species, believed to have originated in East Africa, is renowned for having a larger brain than earlier hominins, with a size range between 775 to 1,250 cubic centimeters. They had significant anatomical differences, including variations in braincase anatomy between populations in different regions. These differences might reflect adaptations to diverse environmental challenges, dietary practices, or developmental patterns. H. erectus exhibits a fascinating evolutionary history, showcasing a mixture of human-like characteristics and primitive traits.
