  "summary": "Evolutionary theory predicts that when hybridization between divergent populations is costly, natural selection should favor traits that reduce further interbreeding, a process known as reinforcement. Direct experimental evidence of reinforcement is rare, however, and no study has demonstrated that reinforcing selection can strengthen reproductive isolation between naive populations while…",
