THE REASON WHY THERE WAS NO FIRST HUMAN

EVO is a book on the evolution of human generations displayed in a single 30 m long page--folded in a zig-zag pattern that traces human history back through 153 generations. Father, grandfather, great grandfather, great,-great grandfather all the way down to the beginning.
