The political left has for too long treated human evolutionary theory with suspicion or, more often, open hostility. Yet dismissing Darwinism as a pseudo-scientific prop for racism, sexism, nationalism and other right-wing prejudice is a tragic own goal, leaving an immensely important topic to bigots and nut jobs, while isolating the left from exciting modern developments within this field. A (R)Evolutionary Left challenges this lazy ignorance, ideological blindness and fervent resistance to Darwinian thinking with open and honest discussion of some of the left's most strongly defended taboos-from eugenics to inherited intelligence to likely evolved differences between the sexes and between human "races". Human beings are the product of the long and complex process of biological evolution that has left its mark on our bodies and on our minds. If we dismiss this reality out of hand-as the left is wont to do-we forgo a better understanding of ourselves. We also miss identifying obstacles to achieving the left's cherished goal of a more just and liveable future society.
