From an evolutionary point of view, avoiding sex with close relatives decreases the chances of passing on a defective gene. Inbreeding can increase the expression of recessive genetic disorders and decrease genetic diversity, which can negatively impact the survival and reproductive success of offspring. Therefore, a universal taboo against sex with close relatives has evolved to promote genetic health and increase the likelihood of producing healthy offspring.
