Botany, also called plant science(s), plant biology or phytology, is the science of plant life and a branch of biology.A botanist, plant scientist or phytologist is a scientist who specialises in this field. Because there was little light in the forest, early primates required visual adaptations for seeing small objects. The visual predation hypothesis states that characteristics that enabled primates to move around trees, such as the visual feature, played a significant role in their evolution because it allowed them to feed on insects on trees and other small animals on the ground Robert Sussman proposed the angiosperm radiation hypothesis. certain primate traits were responses to the accusation of fruit during the Cenozoic. 1 - The arboreal hypothesis proposes that defining primate characteristics were adaptations to life in the trees, such as: a) grasping hands and feet, developed vision, and greater intelligence. DNA degrades over time and the fossils are too old. Skulls and teeth are apelike in appearance; the rest of skeleton is monkeylike. Certain traits, such as visual acuity, occurred in response to the availability of fruit and flowers following the spread of angiosperms. Whoat Where Why.
