How is the unusual flexibility of the human shoulder joint related to the habitat of our primate ancestors?
Travka [436]

Answer:

Explanation:

In the theory of evolution, we evolved from primates such as monkeys. These primate ancestors created habitats high above the ground in the trees. To make this possible and make traversal easier they developed flexible shoulders over the years which allowed them to easily swing from tree to tree, in order to traverse their habitats, reach different foods, and escape from predators with ease. Since this trait was useful to their survival it stuck from generation to generation and is why we as humans have unusual flexibility in our shoulder joint.
