Question

Which of the following statements is true about the skeletons of Homo erectus and modern humans?

a) They are virtually identical
b) Homo erectus skeletons are more robust
c) Homo erectus skeletons are smaller in size
d) Modern human skeletons have a smaller cranial capacity

Answer 1

Homo erectus skeletons were more robust than modern human skeletons with larger jaws, a sloping forehead, and a sagittal keel.

Step-by-step explanation:

The true statement about the skeletons of Homo erectus and modern humans is that Homo erectus skeletons are more robust. Although Homo erectus stood at a height comparable to modern humans and was efficient in bipedal locomotion, they exhibited larger jaws and teeth, a sloping forehead, and a sagittal keel which is a raised ridge on top of the skull. Moreover, their cranial capacity was smaller than that of modern humans, showcasing that there were significant evolutionary changes in both skeletal robustness and brain size leading to the modern Homo sapiens.
