Document Summary
Traditionally includes monkeys, apes and human: non-human primates does not imply superiority, final evolutionary stages are the ones that have become extinct. Group of characteristics that characterize entire primate order includes: limbs and locomotion. Erect posture (esp. in upper body) associated with sitting, leaping, standing, occasionally bipedal walking. 2. flexible generalized limb structure allows various locomotors behaviours: prehensile hands (sometimes feet) used skilfully to manipulate late objects. Retention of 5 digits in hands and feet (some species have reduced thumbs or second digits). Opposable thumb and in most species a divergent big toe (most can move thumb so encounters second digit or palm of hand). Nails instead of claws . except in highly derived new world monkeys all lemurs and lorises also have a claw on one digit. Eyes placed toward front of face (not sides) allows for binocular vision. Visual info from eye transmitted to both hemispheres of the brain.
