Pollinator Hypothesis

Argument that the earliest primates were nectarivorous (see nectarivory) and served as pollinators. Part of their adaptation was color vision by which they could identify the flowers of plants that they pollinated; binocular vision equipped them with depth perception for close work with flowers; grasping hands enabled them to manipulate flowers while inserting their tongues. Aka angiosperm radiation hypothesis, pollinator hypothesis of primate origins.

Cf. arboreal theory of primate evolution and visual predation model.
