| The brain size of Homo habilis was 500-800cc, larger than Austrilopithecus' and approximately 1/2 the size of a human brain. This brain size development is considered the primary reason habilis was the first species ever to make tools like the Oldwalan tools pictured above. However crude in nature, the creation of tools marked the beginning of a long road to civilization.
Habilis lived from approximately 2.2 to 1.6 million years ago. |
