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. The seemingly sudden appearance of so many angiosperm species in the Upper Chalk conflicted strongly with his gradualist perspective on evolutionary change ( Friedman 2009 ). Primates, along with birds and bats, are the most important dispersers of seeds in the tropics. 4) The angiosperm radiation hypothesis. Basal anthropoids are: Eocene primates that are the earliest anthropoids. 39 - The most likely contender for the common ancestor of all later catarrhines is: 40 - The shift from the Miocene, which had greater diversity of ape species and fewer monkey species, to a living assemblage with greater diversity of monkey species and fewer ape species may be the result of: b) differences in ability to exploit the habitats that resulted after a change in global climate. Molecular dating of a supertree of the angiosperms showed a radiation among 'basal . In your answer, consider the effect of climate change on the environment and primates' environmental adaptations.

Arboreal hypothesis: Primates' defining characteristics were adaptations to life in the trees.Angiosperm radiation hypothesis: The grasping hands, grasping feet, and visual acuity of primates were mostly adaptations for eating fruit and other foods made available by modern groups of flowering plants. This radiation "gave rise suddenly and mysteriously to exquisite angiosperm diversity in the mid-Cretaceous," an evolutionary development that troubled Charles Darwin, who saw evolution happening . PLoS One. This result suggests that most of the variation in diversification rates across the angiosperm radiation is not linked to latitude, though some angiosperm lineages can show range-dependent diversification. FOIA Although insects were most likely important components of the diets of the earliest euprimates, it is argued here that visual predation was not the major impetus for the evolution of the adaptive traits of primates.
