Characteristics of Primates

Primates are “unguiculate, claviculate, placental mammals with orbits encircled by bone, three kinds of teeth at one time of life, a well-developed brain with a posterior lobe and calcarine fissure, at least one pair of extremities with an opposable digit, hallux with a flat nail or none, a well-developed caecum, pendulous penis, testes in scrotum, two pectoral mammae.”

Bipedalism refers to the habitual use of two legs for locomotion.

Tactile pads → sensitive fingertips.

7. Taxonomical Classification of Primates

1) Vertical clinging & leaping(4 limbs- hindlimb)

Non-opposable means a thumb, toe, or digit that cannot move inward to touch or face the other fingers or toes on that hand or foot. It cannot form a tight grip against the rest of the digits.

Playback studies (Cheney, Zuberbühler).

Suspensory locomotion is an arboreal movement strategy where an animal hangs or supports its body weight beneath tree branches rather than walking or balancing on top of them.

Studies human–primate interactions.
