On a genetic level, the finding that members of a band are not highly interrelated means that “inclusive fitness cannot explain extensive cooperation in hunter-gatherer bands,” the researchers write. Some evolutionary biologists believe that natural selection can favor groups of people, not just individuals, but the idea is hotly disputed.
tribes with highly cooperative members would prevail over those that were less cohesive, thus promoting genes for cooperation. Hill.
The new data on early human social structure furnishes the context in which two distinctive human behaviors emerged, those of cooperation and social learning, Dr. Hill said. A male chimp may know in his lifetime just 12 other males, all from his own group. But a hunter-gatherer, because of cooperation between bands, may interact with a thousand individuals in his tribe. Because humans are unusually adept at social learning, including copying useful activities from others, a large social network is particularly effective at spreading and accumulating knowledge. qui casca l'asino, quello che non vuole guardare più in là del proprio naso e della prima prostituta all'angolo della strada. e non solo: ecco l'aggiunta finale, sempre in fondo agli articoli, eh, bada bene, di una bella mossa strategica che riporti gli umani che leggono, al regime, quello della guerra. CITAZIONE Dr. Chapais said that the new findings “validate and enrich” the model of human social evolution proposed in his book. “If you take the promiscuity that is the main feature of chimp society, and replace it with pair bonding, you get many of the most important features of human society,” he said. (...) But this cooperation did not mean that everything was peaceful. The bands were just components of tribes, between which warfare may have been intense. “Males could remain as competitive and xenophobic as before at the between-tribe level,” Dr. Chapais writes. chapais, ma vaffanculo, và
