Anthrbio 161 Review Sheet for Midterm Exam 2 Be able to list and discuss the primate unique traits: hand structure, types of locomotion, vision, dental patterns, diet, reproduction and care of offspring o What are the characteristics of each trait Forward facing eyes helps with depth perception stereoscopic vision and judging distances between trees. Grasping hands/opposable thumbs help with grasping Nails not claws (prosimians have both) Color vision to judge ripeness of fruits Dental patterns: 2123 Omnivorous Reproduction: k-selection increase parental investement but fewer offspring. o What is the functional significance of heterodontism Varied teeth help with a non-specialized diet o What cranial and/or morphological traits can be used to distinguished primates from other mammals?
