“To talk of the first humans is to hammer a signpost into an ancient river saying 'no humans beyond this point', no matter the ever flowing stream around it's base. There is nothing essential to humanity, no single feature that intrinsically caused one creature to be human where its parents were not... However hard you try to define every point before the signpost as non-human, and every point after the post as human, the river flows continually.” HumanityHistoryArchaeologyHistory Of MankindEarly Humans Book:Otherlands: A Journey Through Earth's Extinct Worlds Source: Otherlands: A Journey Through Earth's Extinct Worlds
