Which hypothesis posits that primate ancestors adapted visually to hunt in treetop environments?

The Visual Predation Hypothesis posits that primates evolved specific adaptations, particularly enhanced visual and motor skills, to hunt and forage in the complex three-dimensional environments of trees. This hypothesis suggests that early primates adapted to an arboreal lifestyle where visual acuity became essential for detecting prey and navigating through foliage.

The idea is that as these ancestors began to hunt smaller insects and other available prey in the trees, their reliance on vision to identify and track these fast-moving targets became increasingly crucial. This perspective integrates the understanding of evolutionary pressures on sensory systems and behavior in a specific habitat, highlighting how natural selection shaped the visual capabilities of early primates.

In contrast, the other hypotheses do not focus specifically on visual adaptations for hunting in trees, missing the core assertion of how visual abilities evolved due to predation needs in an arboreal setting.
