Question

question 9
which of the following is not an advantage of bipedalism in hominins?
the hands would be free to carry food, tools, and weapons.
walking on two feet requires fewer muscle groups and less energy than walking on all fours.
standing on two feet elevates the head making it easier to see over obstacles and to see farther allowing earlier detection of predators.
standing on two feet makes it easier to climb trees.

Explanation:

Bipedalism in hominins has several advantages. Freeing hands for carrying items, using fewer muscle groups and less energy compared to quadrupedalism, and better vision for predator detection are all valid advantages. However, climbing trees is typically associated with quadrupedal or arboreal adaptations. Bipedalism, which is more suited for terrestrial locomotion, does not make it easier to climb trees.

Answer:

Standing on two feet makes it easier to climb trees.
