The research of Francisco Úbeda, assistant professor of ecology and evolutionary biology, has been featured in the New York Times. The article discusses Úbeda’s mathematical model for assessing the consequences of a woman living in her husband’s village, among people to whom she is not related. His research, which is published in the current issue of Evolution, finds natural selection will favor the activation of paternal genes that underlie altruistic behavior and maternal genes that promote selfishness.
