Document Summary

Forward facing eyes and stereoscopic vision (overlap in visual fields) Complexity of sense of smell reduced in primates for visual evolution. Cathemeral: active any time of day or night. Mammals; warm-blooded, having hair, and feeding milk to young. Warm blooded: cannot use physiology to maintain body temperature (requires heat sources when cold, physical relief from heat when warm) Differ from most mammals by having the combination of: Most eat a variety of fruits, insects, flowers and leaves. A few species specialize by eating mostly or only leaves--which take special gut adaptations to digest--or insects. Generally, larger-bodied species can eat more leaves whereas smaller-bodied species can eat more insects. Moist rhinarium (wet nose)--tightly engaged with its sense of smell to explore its environment. Unfused mandibular and frontal symphases--forehead bone and jaw bone are formed of two parts, fused but not totally sealed, showing a line between them.
