- group socialization
-

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

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)

- nails and tactile pads instead of claws
-
locomotion pattern of most monkeys
quadrupedalism
-
the 2 prosimmian locomotion patterns...
- VCL (vertical clinging and leaping)
- SQC (slow quadrupedal climbing)
-
slow evolutionary rates of change punctuated by spurts of sudden significant change.
punctuated equilibrium
-
mandibular symphasis; postorbital bar-features of the suborder...
Prosimii
-
fused mandible; closed orbits- features of the suborder
Anthropoidea
-
conditions of the Paleocene epoch: 3
- warm, humid, tropical worldwide
- connected landmasses
- pre-Paleocene; dinosaurs die off
-
Eocene epoch: 3 major catagories
- Global cooling and drying
- polar ice caps grow
- ocean level drops
- Changes in flora
- temperate forests grow
- Adapt
- "euprimates" appear
- prosimians only
