Reverse magic effect: underappreciated contributions of pleiotropy to the lineage persistence during speciation【B】【O】

*Daisuke KYOGOKU(Mus Nat Hum Act), Yume IMADA(Kyoto Univ.)

Many species appear to arise through nonecological speciation, and many nascent species do not persist long. How do some of the ecologically similar species persist long, contributing to the accumulation of species diversity? Here, focusing on relatively late stages of speciation, we suggest that selection for reproductive trait divergence between lineages may pleiotropically enhance their ecological coexistence. Because this argument assumes the reverse causality of the so-called magic trait model, we dub it the reverse magic effect. Reverse magic effects can be found in many existing models, and some empirical studies are consistent with our prediction. The implications of our discussion are potentially broad and not limited to magic trait models, and thus the roles of reverse magic effect in lineage persistence deserves more consideration.
