Question

question 2
which of the following is not an advantage of bipedalism in hominins?
the hands would be free to carry food, tools, and weapons.
standing on two feet elevates the head making it easier to see over obstacles and to see farther allowing earlier detection of predators.
walking on two feet requires fewer muscle groups and less energy than walking on all fours.
standing on two feet makes it easier to climb trees.

Explanation:

Bipedalism offers several advantages such as freeing hands for carrying items (first option), elevating the head for better vision (second option), and being more energy - efficient (third option). However, climbing trees is more associated with quadrupedal or arboreal (tree - dwelling) locomotion. Bipedalism is a terrestrial adaptation and does not make it easier to climb trees.

Answer:

Standing on two feet makes it easier to climb trees.
