- primate characteristics: skeletal anatomy
- female sexual receptivity, care and nurture of infants
- primates: social behavior
- connects brain with the spinal cord and gives primates their upright posture
- foramen magnum
- to test hypothesises about early human ancestor behavior, ex. the savannah dwelling toolmaking hypothesis

- stereoscopic vision, fovea centralis, touch
- primate characteristics: sense organs
- allows for depth perception and the ability to see in colour

- ability to focus on a single point
- fovea centralis
- larger capacity (related to visual acuity), balance
