It may seem odd that adaptations that make us better able to walk would make other activities, like climbing trees, more difficult. Being able to climb trees is important for both feeding on fruit and escaping predators. Each location features a giant 3,000 square foot play structure for. One in about 13 people have more floppy feet, pointing toward a bone structure more akin to that found in fossils of 2 million-year-old human ancestors. Our big toe cannot grasp the branches as well as other primates. Cheeky Monkeys offer the best kids birthday party packages in Fairview and Plano. However, it also makes our ability to climb in trees clumsy and less efficient. Our big toe, or hallux, is positioned next to our other toes. This position is ideal for toeing off (pushing off with the toe) from the ground during walking. We have very long legs with muscles ideally oriented for bipedal locomotion. Perhaps your mom or grandpa suffers from back pain. For example, the curvature of the lower spine, or lordosis, makes it easier to balance on two legs. However, pain is frequently experienced when the back curves too much due to weakened muscles or illness. However, the physical changes required for bipedal walking have negative effects on our bodies. Long before we used our hands to text on phones while walking, our hominin ancestors used their free hands to carry tools and even infants (as human babies cannot cling to their mothers). ![]() ![]() One benefit of bipedal locomotion is that it frees the hands for carrying tools. However, these benefits of walking on two legs may make other activities more difficult. Bipedal locomotion, or walking on two legs, has many benefits:ġ) It frees the hands for carrying tools and infantsģ) It allowed our ancestors to see over the tall grasses ![]()
