  1. the "handfull" of traits (and two more)that came of the arborial radiation.
    • pentadactylism
    • better vision
    • decreased sense of smell
    • thumbs
    • nails
    • longer gestation
    • group socialization
  2. location, time of day, diet
  3. what happens when Gaussian competition is fierce, there is an empty niche in a new area, and the creature is pre-adapted for it...
    adaptive radiation
  4. Why, according to the guy at Duke U, are squirrles not primates?
    • "Visual Predation Model"
    • hunting at the terminal ends of branches
    • light body (12-18oz)
    • developed depth perception
    • nails and tactile pads instead of claws
  5. locomotion pattern of most monkeys
  6. the 2 prosimmian locomotion patterns...
    • VCL (vertical clinging and leaping)
    • SQC (slow quadrupedal climbing)
  7. slow evolutionary rates of change punctuated by spurts of sudden significant change.
    punctuated equilibrium
  8. mandibular symphasis; postorbital bar-features of the suborder...
  9. fused mandible; closed orbits- features of the suborder
