ANTH 2700 Chapter Notes - Chapter 7: Tapetum Lucidum, Visual Acuity, Color Vision
Document Summary
Evolution of various features in primates result from. Leaping patterns of locomotion in which grasping branches was important for climbing and landing. Consumption of fruits that grow on the ends of slender branches. Pentadactylism: possessing five digits on the hand and/or food. Opposable thumb: anatomical arrangement in which the fleshy tip of the thumb can touch the fleshy tip of all the fingers. Epidermal ridges: the pattern of ridges found on the hands and feet that form "fingerprint" patterns; richly endowed with nerve endings that are associated with a refined sense of touch. Tactile pads: tips of the fingers and toes of primates; areas richly endowed by tactile nerve endings sensitive to touch. Most primates see in 3d and in color, but development of color vision varies. Retina: the layer of cells in the back of the eye that contains the cells - rods and cones.
