  "summary": "Genetic conflict drives evolutionary innovation, yet most research has focused on arms races between selfish elements and their hosts. A second layer-competition among selfish elements-remains largely unexplored. Here, we uncover such a conflict between two antagonistic toxin-antidote elements (TAs), loki-1/sgyn-1 and thor-1/sif-1, in Caenorhabditis tropicalis. Each toxin, LOKI-1 or THOR-1,…",
