Document Summary
Periods that we divide the earth into in which there are primates (starting at the end of. Crutaceous and at the beginning of the cenozoic- the age of mammals) Jurassic (135 mya: laurasia and gondwanaland. In paleocene (65 mya: continents start to separate. Now: continents are still moving, the galapagos and hawaiian islands are moving relatively quickly. First primate-like mammal: purgatorius, from purgatory hill, montana. Radiation of plesiadapids; rodent-like primates: plesia=near to, so they are like the dapids . Origin of angiosperms- flowering plants: ferns, evergreens, redwoods were before and flowering plants developed once the bee evolved, they co-evolved. Rise of rodents; which may have driven plesiadapids into extinction. Adapids (adapidae) are the earliest family of primates. Darwinius- name of the fossil of the first official known primate. Monkeys from south america may have come from either africa or north america (they can float via island/rafts) Forests begin to be replaced by grassland in some regions.
