I remember in history class, at this period humans are merely discovering stone tools and discovery of fire. Yet here, researchers presented evidence of tools from boat-makers and other technology where humans navigate on deep waters? this is crazy!

This article is about 40,000 years ago.

Fire was controled like 1,000,000 years ago by Homo erectus and stone tools like 3,000,000 years ago by Australopithecus afarensis.
