Researchers have uncovered how two closely related moth species in the southeastern U.S. evolved into separate species by shifting their active periods. Instead of a physical barrier, the key difference lies in their circadian rhythms, regulated by clock genes. This discovery provides a rare glimpse into speciation at the molecular level and highlights the importance of studying diverse species to understand broader biological patterns.
