Page "Human evolution" Paragraph 2

The earliest documented members of the genus Homo are Homo habilis which evolved around.

Homo habilis is the first species for which we have positive evidence of use of stone tools.

The brains of these early homininas were about the same size as that of a chimpanzee.

During the next million years a process of encephalization began, and with the arrival of Homo erectus in the fossil record, cranial capacity had doubled to 850cc.

Homo erectus and Homo ergaster were the first of the hominina to leave Africa, and these species spread through Africa, Asia, and Europe between.

It is believed that these species were the first to use fire and complex tools.

According to the Recent African Ancestry theory, modern humans evolved in Africa possibly from Homo heidelbergensis and migrated out of the continent some 50, 000 to 100, 000 years ago, replacing local populations of Homo erectus and Homo neanderthalensis.
