The cranium size of Homo erectus is generally smaller than that of modern Homo sapiens. Homo erectus had an average cranial capacity of about 900-1100 cubic centimeters, while modern Homo sapiens have an average cranial capacity of about 1350 cubic centimeters. This indicates that modern humans have larger brains than Homo erectus. In addition to the overall size difference, there are also differences in the shape and structure of the cranium between Homo erectus and modern Homo sapiens. Homo erectus had a more pronounced brow ridge and a larger, more elongated skull compared to modern humans. Modern Homo sapiens have a more rounded skull with a less prominent brow ridge. These differences in cranium size and shape suggest that there have been significant changes in the evolution of the human brain from the time of Homo erectus to modern Homo sapiens. The larger and differently shaped cranium of modern humans likely reflects changes in brain size and organization, which may have contributed to the development of advanced cognitive abilities and behaviors.
