Document Summary
Lecture 8 - overview of the living primates: prosimians and new. Survey of the living primates: strepsirhines. The arboreal hypothesis the primate pattern represents an adaptation to an arboreal habitat or to life in the trees. Other modes of detection (some use sound) Early marsupials had grasping hands before evolution of flowering plants. Plenty of animals have a varied diet and are nocturnal. Which is the best hypothesis: does watching wild primates shed light on the best theory, kind of. Most primates live in the tropics and/or below the equator: some (very few) kinds of primates in asia will live in very cold regions. Locomotion: quadrupedal = walking on all four limbs. Measure of the relative length of upper and lower limbs (humerus length + radius length)/(femur length + tibia length) x 100. 100-120 = brachiation: vertical clinging and leaping. Forced to leap and bounce across gaps in trees.
