The rise of homo sapiens

Abstract

Already animals use production and information tools and so did our ancestors, the hominids. With the appearance of our species, Homo sapiens, and in particular in the Stone Age Revolution, major progress was made, resulting not only in more refined and more complex production tools, but also in more complex information tools. In this respect the development of human language was absolutely crucial for everything that followed. Whistle and drum languages are interesting variations that nicely illustrate human ingenuity.
