Angiosperm Radiation Hypothesis

Hypothesis proposed by Robert Sussman that posits that many primate traits are the result of coevolution with angiosperms, in which many early primates exploited the products of these plants in low-light canopy conditions; binocular vision, color vision and grasping hands were selected for observing and manipulating fruiting plants; some early primates are speculated to have served as pollinators. Aka pollinator hypothesis, terminal branch-feeding hypothesis.
