Darwin’s own clear logic said: “The moral sense perhaps affords the best…distinction between man and the lower animals…the social instincts, the prime principle of man’s moral constitution…naturally lead to the golden rule, “As ye would have men should do to you, do ye to them likewise.” Not so “Darwinian.” Darwin knew we are by nature self-deficient and interdependent. The specious origin of what’s called “Darwinian” is Herbert Spencer, coiner of “survival of the fittest.” It descends to us via Dawkinsian selfish-genery. But Dawkins’ logic is flawed. Nature contains competition. But also cooperation. The mix is key, especially in social species. The largest study of hunter-gatherer tribal rules shows that team survival has likely shaped our evolution, and social rules, for 10,000 generations. All extant hunter-gatherers limit group-threatening behaviors, including harmful competition. There are two types of social rules: Those that prevent groups from damaging what they depend on. And those that don’t. Guess which are fitter? Darwin knew better than today’s “Darwinians” that though we evolved like other species, we’re different. We are the giraffes of cooperation, having uniquely extended features for teamwork. Darwin’s moral sense, as Jefferson said, was “as much a part of a man as his arm or leg.” Ignoring our innate social-rule-processors is unnaturally selective. - blogs.scientificamerican.com
