Widespread but cryptic introgression shapes genetic diversity in natural populations

Guillaume Lavanchy, Ludovic Ruedi, Olivier Broennimann, Kristine Jecha, Marianne Tzivanopoulos, Jérôme Goudet, Tanja Schwander

The paper quantifies introgression in 4126 ant colonies, finding 23% of species show introgression, more than double previous estimates, and suggests postzygotic barriers constrain it.
