Genetic Influence On Cultural Evolution
Genes have an impact on cultural evolution via psychological predispositions on cultural learning. Genes encode much of the information needed to form the human brain. Genes constrain the brain's structure and, hence, the ability of the brain to acquire and store culture. Genes may also endow individuals with certain types of transmission bias (described below).

Famous quotes containing the words genetic influence, genetic, influence, cultural and/or evolution:
“Nature, we are starting to realize, is every bit as important as nurture. Genetic influences, brain chemistry, and neurological development contribute strongly to who we are as children and what we become as adults. For example, tendencies to excessive worrying or timidity, leadership qualities, risk taking, obedience to authority, all appear to have a constitutional aspect.”
—Stanley Turecki (20th century)
“We cannot think of a legitimate argument why ... whites and blacks need be affected by the knowledge that an aggregate difference in measured intelligence is genetic instead of environmental.... Given a chance, each clan ... will encounter the world with confidence in its own worth and, most importantly, will be unconcerned about comparing its accomplishments line-by-line with those of any other clan. This is wise ethnocentricism.”
—Richard Herrnstein (1930–1994)
“Constitutional statutes ... which embody the settled public opinion of the people who enacted them and whom they are to govern—can always be enforced. But if they embody only the sentiments of a bare majority, pronounced under the influence of a temporary excitement, they will, if strenuously opposed, always fail of their object; nay, they are likely to injure the cause they are framed to advance.”
—Rutherford Birchard Hayes (1822–1893)
“If in the earlier part of the century, middle-class children suffered from overattentive mothers, from being “mother’s only accomplishment,” today’s children may suffer from an underestimation of their needs. Our idea of what a child needs in each case reflects what parents need. The child’s needs are thus a cultural football in an economic and marital game.”
—Arlie Hochschild (20th century)
“The more specific idea of evolution now reached is—a change from an indefinite, incoherent homogeneity to a definite, coherent heterogeneity, accompanying the dissipation of motion and integration of matter.”
—Herbert Spencer (1820–1903)
