Unit 1: The Process of Hominisation

Definition: Combination of successive changes that affected some primates (the hominids) until they became today’s human beings. This process started in the east of Africa some six million years ago.

Most important anatomical changes:

• Bipedalism (as opposed to quadrupedalism) allowed hominids to move on just their lower limbs, leaving the upper limbs for manipulating tools.

• The development of opposable thumbs allowed hominids to firmly hold objects in their hands. It allowed for manual tasks and the creation of tools.  

• Development of the brain and the forehead – this is related to the development of intelligence. 

• Changes in the larynx made it possible to develop language.

• Reduction in the size of the jaw and teeth.
