However, these ideas are not new. Here I review early work by Patton and colleagues on hybridization, gene flow, and the nature of species boundaries in pocket gophers and argue that a focus on the underlying biology of the organism provides insights into hybridization and gene flow that are not obtainable from genomic data alone.]]></p></abstract>

Sin embargo, estas ideas no son nuevas. En este artículo, analizo los primeros trabajos de Patton y sus colegas sobre la hibridación, el flujo genético y la naturaleza de los límites entre especies en las tuzas y sostengo que un enfoque en la biología subyacente del organismo proporciona conocimientos sobre la hibridación y el flujo genético que no se pueden obtener a partir de datos genómicos únicamente.]]></p></abstract>
