Question 4

Homo erectus's high degree of adaptive success is evidenced by its:

Accepted Answer

Homo erectus's adaptive success is demonstrated by both its increased reliance on material culture, such as the use of fire and more complex tools, and its apparent increase in brain size and intelligence compared to earlier hominids. Additionally, Homo erectus's ability to adapt and thrive in a range of environments, from African savannas to East Asian forests, further supports their success as a species.

Question 6

Greater body size and facial gracility documented in Homo erectus are likely related to:

Accepted Answer

The changes in body size and facial gracility seen in Homo erectus coincide with the emergence of stone tool technology and increased consumption of meat and other proteins, which would have necessitated more efficient hunting and gathering abilities. These adaptations would have provided selective advantages for individuals with larger body size and stronger facial features for processing food.
