Nurture refers to all the environmental variables that impact who we are, including our early childhood experiences, how we were raised, our social relationships, and our surrounding culture
While certain physical traits like skin and eye color and diseases like sickle cell anemia and Huntington’s chorea have been found to be the result of direct genetic inheritance, virtually any pattern of thinking or behavior can be understood from the perspective of a combination of nature and nurture. In the animal kingdom, domestication of many species is understood to be the result of encouraging domesticated behaviors (nurture), then having animals that most successfully adopt those behaviors breed with each other so it becomes part of their nature (Bouchard, 1994).
In humans, many studies in more than the past 20 years involve identical or fraternal twins who are separated at birth. The question of nature vs. nurture somewhat continues to be debated concerning human behavior, intelligence, and in the development of personality traits
