We live in an artificial world built around convenience and comfort. This allows natural selection to bend its traditional rules, creating offspring who may not possess the same genetic advantages that would historically have been necessary for survival. Traits that might once have reduced an individual's chances of surviving and reproducing can persist across generations because modern society provides artificial safeguards against many environmental pressures. In a sense, civilization has weakened the relationship between genetic fitness and reproductive success, allowing human evolution to follow a different trajectory than it would under harsher natural conditions.
