Mean Genes

Short, sassy, and bold, Mean Genesuses a Darwinian lens to examine the issues that most deeply affect our lives: body image, money, addiction, violence, and the endless search for happiness, love, and fidelity. But Burnham and Phelan don't simply describe the connections between our genes and our behavior; they also outline steps that we can take to tame our primal instincts and so improve the quality of our lives.Why do we want (and do) so many things that are bad for us? We vow to lose those extra five pounds, put more money in the bank, and mend neglected relationships, but our attempts often end in failure. Mean Genesreveals that struggles for self-improvement are, in fact, battles against our own genes--genes that helped our cavewoman and caveman ancestors flourish but that are selfish and out of place in the modern world. Why do we like junk food more than fruit? Why is the road to romance so rocky? Why is happiness so elusive? What drives us into debt? An investigation into the biological nature of temptation and the struggle for control, Mean Genesanswers these and other fundamental questions about human nature while giving us an edge to lead more satisfying lives.
