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)
“What strikes many twin researchers now is not how much identical twins are alike, but rather how different they are, given the same genetic makeup....Multiples don’t walk around in lockstep, talking in unison, thinking identical thoughts. The bond for normal twins, whether they are identical or fraternal, is based on how they, as individuals who are keenly aware of the differences between them, learn to relate to one another.”
—Pamela Patrick Novotny (20th century)
“We could not well camp higher, for want of fuel; and the trees here seemed so evergreen and sappy, that we almost doubted if they would acknowledge the influence of fire; but fire prevailed at last, and blazed here, too, like a good citizen of the world.”
—Henry David Thoreau (1817–1862)
“The only justification for repressive institutions is material and cultural deficit. But such institutions, at certain stages of history, perpetuate and produce such a deficit, and even threaten human survival.”
—Noam Chomsky (b. 1928)
“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)
