Can science tell us whether blood is thicker than water? Are we particularly nice to our blood kin and, if so, why? In The Altruism Equation, Dr. Lee Alan Dugatkin tells the story of the fierce debate about altruism and kinship among evolutionary biologists, Before the debate was over, politics, philosophy, even religion, would enter the fray, complicating for close to a century attempts to find and settle on a scientific answer to a scientific question. Today that answer is known as “Hamilton’s Rule,” which states that relatives are worth helping in direct proportion to their genetic relatedness. The engine of goodness, Hamilton’s Rule suggests, lies in the family unit. This rule has been as influential on evolutionary biology as Newton’s Laws of Motion have been on physics.
Lee Alan Dugatkin, PhD is Professor and Distinguished University Scholar in the Department of Biology at The University of Louisville.
