Bipedalism,considered a key defining characteristic that differentiated early hominins from other apes,

Question

Quizplus · Accepted Answer

The theory is that bipedalism evolved in a woodland habitat but became even more advantageous in a savanna habitat, where it facilitated long-distance walking and improved thermoregulation.

Answer: B 
 The increase in brain size may have driven the anatomical changes necessary for bipedalism, as a larger brain would require a wider pelvis, shorter birth canal, and other changes that may have facilitated upright walking.

Answer: A, D, and E are incorrect. Stone tool production is not strongly linked to the evolution of bipedalism, and there is no evidence that bipedalism led to a sharp increase in climbing abilities or that it resulted in significant heat stress.
