Angiosperms The angiosperms, or flowering plants, are the largest and most species-rich phylum of plants, with more than 250,000 species estimated Defining Characteristics The term "angiosperm" derives from two Greek words: angeion, meaning "vessel," and sperma, meaning "seed " The angiosperms . i. Paleocene fossils a possible candidate for the early primate ancestor ii. DEFINITION 5 According to the angiosperm radiation hypothesis, the original primate adaptation was about getting fruit, not preying on insects. The visual predation hypothesis acknowledges that some arboreal species (such as squirrels) do not possess these key primate features, so instead it focuses on stereoscopic vision and grasping as means of catching insects. pro primates.

">. Four competing hypotheses attempt to explain how anthropoids got to. Thus, it is suggested here that the multitude of resources available on the terminal branches of the newly evolved angiosperm, rain forest trees led to the morphological adaptations of primates of modern aspect. 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. Basal anthropoids are: Eocene primates that are the earliest anthropoids. What were some of their features? The Anthostrobilus (Bennettitalean) Theory 5.

Traditionally, the morphological traits of primates were assumed to be adaptations to an arboreal way of life. In fact, decades later, Darwin hypothesized that one possible explanation for an evolutionary radiation associated with the origin of angiosperms (if such a radiation must be accepted) was an elevated evolutionary rate driven by coevolution with insect pollinators (see [6]).
