The view that humans acquire all or almost all of their behavioral traits from "nurture" was termed tabula rasa, Latin for "blank slate," by philosopher John Locke. This idea proposes that humans develop only from environmental influences. One example of a person's trait that is completely determined by their environment is native language. Studies show that children, regardless of where they're born, can learn any language with equal facility.
The term "nurture" has historically been defined as the care given to children by the parents, with the mother playing an important role. Now, this term is regarded by some as the environmental (non-genetic) factor of a person's environment. This new definition of "nurture" has been expanded to include, not just a person's family upbringing, but also everything else they experience in daily life including advertisements, media, education, peer influences, and home environments.
Some scientists have concluded that a person's nature—meaning the traits they got from their parents—have more power in determining a person's identity than how they are nurtured, or raised. Inherited traits are traits that are developed before birth.
Some genetic traits are highly heritable, such as eye color. Some disorders or diseases are also heritable.
