Whole-genome sequences of 89 Chinese sheep suggest role of <i>RXFP2</i> in the development of unique horn phenotype as response to semi-feralization

Semi-feralization has an extensive impact on diverse phenotypic traits of sheep. By acquiring features like those of their wild ancestors, semi-feral sheep were able to regain fitness while in frequent contact with wild surroundings and rare human interventions. This study provides a new insight into the evolution of domestic animals when human interventions are no longer dominant.
