Evolutionary biologists determine that culture shapes genetics within, not just between, populations
Nicole Creanza and Yakov Pichkar explore whether subtle cultural differences within a language mirror genetic structure within a population. The answer: Even small cultural differences like dialect can influence the spread of people and genes. Read MoreJun 29, 2023
