Question

Quizplus · Accepted Answer

The dietary model that suggests standing upright to collect fruit from trees is the most influential for bipedalism as it explains how early hominins developed bipedalism to access food sources that were higher up in trees. This model is supported by evidence such as the shape of early hominin hands, dentition, and the fossil record. The other choices, such as hunting with weapons and collecting handfuls of grass seeds, may have also contributed to the evolution of bipedalism, but they are not as widely accepted as the fruit-gathering model. Standing upright to increase the line of sight when looking for food is also a possible contributing factor, but it does not specifically address the importance of bipedalism for accessing food in trees.
