The Development of Upright Posture in Hominins is Likely an Adaptation

Question

The development of upright posture in hominins is likely an adaptation for
A) living on the ground instead of in the trees.
B) living on land instead of on the water.
C) no longer needing to carry tools.
D) having no functional knees.

Accepted Answer

The development of upright posture would have allowed hominins to more efficiently move and navigate on two legs, which would have been advantageous for living on the ground and traversing open savanna environments. This would also free up their arms and hands for carrying tools, gathering food, and other activities necessary for survival.
