Question

Quizplus · Accepted Answer

Upright walking allowed early humans to free their hands for gathering and carrying food, which was a crucial factor in their ability to survive and evolve. The ability to carry food also facilitated social interactions and cooperation within groups, leading to further development and complexity in human societies. While upright walking may also provide benefits such as good posture and circulation, these are not as significant in terms of the evolutionary significance of upright walking. Digestion, on the other hand, is not directly related to upright walking.
