TERM 22 Is the hypothesis that platyrrhine in Africa and South America originated independently valid? Angiosperms, which evolved in the Cretaceous period, are a diverse group of plants which protect their seeds within an ovary called a fruit. Robert Sussman proposed. As a result of long-term diffuse coevolutionary interactions with flowering plants, modern primates, bats, and plant-feeding birds all first arose around the Paleocene-Eocene boundary and became the major seed dispersers of modern tropical flora during the Eocene. Is there confession in the Armenian Church. B. Smuts, D. L. Cheney, R. M. Seyfarth, R. W. Wrangham, T. T. Struhsaker eds.

Peniophora is an old corticioid genus, from which two small satellite genera, Dendrophora and Duportella, were derived based on morphological differences. Visual predation hypothesis: Unique primate traits arose as adaptations for preying on insects and other small animals. However, recent research on nocturnal primates does not support the visually-oriented predation theory.

Robert Sussman hypothesized that the visual acuity grasping hands, and grasping feet of primates were mostly adaptations for eating fruit and other foods made available with the radiation of modern groups of flowering plants called angiosperms. Angiosperm radiation hypothesis. The angiosperms showed a radiation among & # x27 ; basal review: angiosperm phylogeny evolutionary! TERM 5 Why was the visual predation hypothesis challenged? However, plate tectonic movement caused mountain ranges to form and ocean currents to shift, thereby creating dramatic changes in climate and ecology. In this regard, what are two theories proposed to explain primate origins? 1) There were no scavengers living in . answer. - However, this visual predation hypothesis does not explain fruit-eating in primates.

TERM 21 Is the hypothesis that platyrrhine traveled from Africa to Antarctica to South America valid? According to the theory, known as the angiosperm coevolution hypothesis, long ago, our primate ancestors evolved key adaptations like forward-facing eyes, excellent colour vision, rounded, blunt teeth and fingers without claws, all for the purpose of eating and living from fruits.
