Introduction

Mark pagel: Human beings are the only species with a history. We have gone from being a species that may just few simple hand axes to one that can make spaceships, smart phones and driverless cars. Contrast this with our wretched cousins, the chimpanzees who still sit on the forest floor cracking nuts with the same old stones as they have for millions of years,. Why this difference? Mark pagel: You are not as clever as you think.
