      Some of those genes were probably helpful in some way in a different context. Kind of like sickle cell in people from malaria prone areas and genes that made the plague less deadly but also make autoimmune diseases more likely. People often forget that there usually aren’t many universally superior genes, just genes that help someone survive better in a specific context. The value of traits is relative.
