Final answer:
The visual predation hypothesis explains the origins of unique primate traits as adaptations for preying on insects and small animals. Primate features may have arisen as adaptations that helped early primates succeed as predators.
Step-by-step explanation:
The visual predation hypothesis is a hypothesis that explains the origins of unique primate traits as adaptations for preying on insects and small animals. According to this hypothesis, primate features such as forward-facing eyes, grasping hands and feet, and the presence of nails instead of claws may have arisen as adaptations that helped early primates succeed as predators in the shrubby forest undergrowth and the lowest tiers of the forest canopy.
