Grasping hands and feet were crucial to holding onto tree branches, binocular vision allowed greater depth perception for judging distance in the movement from tree to tree, smell was no longer necessary for finding food, and greater intelligence was important for understanding 3-dimensional space in trees. However, Cartmill [1972] pointed out that a number of morphological traits characteristic of primates are not found in many other arboreal mammals. The angiosperm radiation is one of the evolutionary events that most puzzled Darwin. c) certain primate traits were responses to the acquisition of fruit during the Cenozoic.

The best-accepted hypothesis for the dispersal of African monkeys to the New World is that: platyrrhines evolved from anthropoids in Africa that migrated across the Atlantic to South America. 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]). 1) There were no scavengers living in . Their radiation was characterized by high and rapid diversification (3, 4), high rates of speciation throughout the Cretaceous (5), and unprecedented ecological dominance. {"cdnAssetsUrl":"","site_dot_caption":"Cram.com","premium_user":false,"premium_set":true,"payreferer":"clone_set","payreferer_set_title":"Anthro Chap 9","payreferer_url":"\/flashcards\/copy\/anthro-chap-9-8031568","isGuest":true,"ga_id":"UA-272909-1","facebook":{"clientId":"363499237066029","version":"v12.0","language":"en_US"}}.

One explanation proposed that fluctuations in the quantities of carbon dioxide in the atmosphere brought on by volcanic activity were the primary cause of the ice age cycle. Although the timing of the origin of flowering plants is debated (2531), there is consensus that they radiated in the Early Cretaceous (145 Ma) and are the most recently diversifying major clade among the land plants (2531).
