Question
Complete each statement below about the transition from arboreal to bipedal animals by placing the proper word in the proper word in the appropriate position. Humans are theorized to have descended from ancestors that were__, or tree-dwelling creatures. The ability of the thumb to cross over the palm and contact the smallest digit describes __functionality. Due to the adaptation of opposition__, function allowed a species the ability to grasp, and thus to better cling, to branches. An adaptation of the yes, resulting in a large portion of the visual field being seen in duplicate allowed for __vision. Visual inputs from two slightly different positions in space allowed from depth perception and increased maneuverability in the trees. As human ancestors transitioned to terrestrial existences, __developed. This allowed for greater altitude of observation while on the ground and the ability to use the hands and arms for carrying objects during locomotion.Explanation / Answer
Solution:
Humans are theorized to have descended from ancestors that were arboreal or tree-dwelling creatures.
The ability of the thumb to cross over the palm and contact the smallest digit describes opposable functionality.
Due to the adaptation of opposition, prehensive function allowed a species the ability to grasp, and thus to better cling, to branches.
An adaptation of the eyes, resulting in a large portion of the visual field being seen in duplicate, allowed for stereoscopic vision. Visual inputs from two slightly different positions in space allowed for depth perception and increased maneuverability in the trees.
As human ancestors transitioned to terrestrial existences, bipedalism developed. This allowed for greater altitude of observation while on the ground and the ability to use the hands and arms for carrying objects during locomotion.
