Sticks and stones picked up unaltered from the ground were probably the only implements used by the great apes and earliest human ancestors. Beginning in the Miocene in Africa, then in Europe and Asia, primates had characteristics seen in extant apes particularly in dental and skull morphology, though many still retained very primitive body sizes and morphology. These changes have resulted in dramatic increase in brain size and the reorganisation of the brain in which some parts, such as those involved in learning, have developed more than others, such as smell and vision, Reconstructing the physical environment in which our ancestors lived allows us to gain a greater understanding of their day-to-day lives.
