Resumen de Why manners matter
A crucial factor in human evolution is so deeply ingrained in their lives that they barely notice it. Here, Curtis lifts the lid. She says the acquisition of manners was one of the first baby steps humans took on the road to large-scale cooperation, and cooperation, underpinned by their moral sense, was the great leap forward that allowed humans to become a hyper-social species. They have since worked together to achieve technical dominance of the planet. If they can better understand how microbes gave them manners and manners then shaped their morality, it might hold clues for their future as a species.
