Because alleged greater organisms such as for example humans are at risk of life-shortening hereditary combinations, Lieberman believes nature has weeded away incestuous behavior over time through normal selection. Humans along with other pets, she stated, most likely evolved approaches to identify and give a wide berth to mating along with their relatives that are close.
