Eugenics, for example, was a movement heavily influenced by the nativist approach. This realization is especially important given the recent advances in genetics, such as polygenic testing. Other things like life expectancy and height have a strong biological component, but they are also influenced by environmental factors and lifestyle. Characteristics and differences that are not observable at birth, but which emerge later in life, are regarded as the product of maturation.

This means that what sometimes appears to be an environmental influence nurture is a genetic influence nature. Aspects of the theory of syntax. In a society in which plenty of words are available in everyone's environment, especially for individuals who are motivated to seek them out, the number of words that individuals actually learn depends to a considerable extent on their genetic predispositions and thus heritability is high.
