Question

The 'predation theory' and the 'arboreal hypothesis' are both theories proposed to explain the same common primate trait. This trait is known as _______________.

A. Allogrooming
B. A Pehensile Tail
C. Stereoscopic Vision
D. The Use of Stone Tools
E. None of the Above

Answer 1

Both the 'predation theory' and the 'arboreal hypothesis' attempt to explain the presence of stereoscopic vision in primates, with the former attributing it to predatory adaptations and the latter to life in trees.

Step-by-step explanation:

The 'predation theory' and the 'arboreal hypothesis' are both theories proposed to explain the same common primate trait, which is C. Stereoscopic Vision. The arboreal theory suggests that primates evolved unique traits like grasping hands and feet, and forward-facing eyes to help them live in trees. In contrast, the visual predation hypothesis, proposed by anthropologist Matt Cartmill, argues that these traits evolved to aid early primates in hunting insects and small animals, especially in the lower levels of forests where good depth perception and the ability to grab prey swiftly were advantageous.

Both theories seek to explain why primates, including humans, have eyes that face forward, offering a broad range of vision that overlaps, allowing for the perception of depth crucial for both arboreal navigation and hunting small prey.
