How would the lack of binocular vision affect the survival of a primate?

The lack of binocular vision would significantly impair a primate's ability to judge distances accurately, which is crucial for navigating complex environments, locating food, and avoiding predators. Without the depth perception provided by binocular vision, a primate might struggle with activities such as climbing, jumping, and grasping objects, ultimately affecting its foraging efficiency and social interactions. This could lead to decreased survival rates, as the primate would be at a disadvantage in both capturing prey and escaping threats. Overall, the absence of binocular vision would hinder a primate's adaptability to its ecological niche.
