Primate characteristics: limbs and locomotion: tendency toward erect posture, flexible limb structure, hands and feet with a high degree of prehensility, opposable thumb, nails instead of claws, tactile pads. All four limbs support the body: brachiation. Support alternated from one forelimb to the other: clinging and leaping, knuckle-walking, bipedalism.
