Physical Characteristics

The body of humans is described in the human anatomy group of articles. Humans have a wide range of variability in physical and other characteristics.

The evolution of Homo sapiens is characterized by a number of important trends:

* expansion of the brain cavity and brain itself, which is typically about 1,400 cm³ in volume, well over twice that of a chimpanzee or gorilla. Some physical anthropologists argue that a reorganization of the structure of the brain is more important than cranial expansion itself.
* canine tooth reduction.
* bipedal locomotion
* descent of the larynx (which makes possible the production of the complex sound known as vocal language).
