They are visual predation hypotheses, arboreal hypotheses, and angiosperm- primate co-evolution hypotheses. b. fruit was a newly available food source in the Cenozoic era. . We now know that the Angiosperm Radiation Theory explains many of these primate traits because primates and flowering plants called angiosperms (plants with fruit or flowers) co-evolved with primates. The angiosperm radiation hypothesis proposes that: Certain primate traits were responses to the evolutionary spread of fruit tress during the Cenozoic. Two genera of propliopithecids include: Propliopithecus and Aegyptopithecus The host says that there is a six-million-year gap in the fossil evidence between the latest Oligocene catarrhines and the earliest Miocene proconsulids, which could mean that primates disappeared from Earth and evolved anew some time later.

TERM 7 Who were the Euprimates? The evolution of plants has resulted in a wide range of complexity, from the earliest algal mats, through multicellular marine and freshwater green algae, terrestrial bryophytes, lycopods and ferns, to the complex gymnosperms and angiosperms (flowering plants) of today.

That may have been the first primates were in fact, he famously referred to it as an to. One possibility is an Eocene primate called a basal anthropoid. In trying to understand primate evolution, it is clear that certain primate traits were responses to the acquisition of fruit during the Cenozoic period; this assumption is proposed as the angiosperm radiation hypothesis. What does the arboreal hypothesis of primate origins explain? Why big brains? Certain traits, such as visual acuity, occurred in response to the availability of fruit and flowers following the spread of angiosperms. The 1750s research on string vibration and sound propagation laid the groundwork for this theory. Euprimates represent the: first true primates.
