This study systematically rejects the long-standing notion of cospeciation as the dominant driver of codiversification between flowering plants and their specialist pollinators. Through cophylogenetic analysis of six classical specialized pollination systems, the research finds that cospeciation events are consistently outnumbered by non-cospeciation events, such as host-switch, duplication, and association losses. The findings support a more dynamic and diffuse codiversification paradigm, highlighting the importance of considering a broader range of evolutionary events in understanding plant-pollinator codiversification. This new understanding is robust across diverse pollination systems and has significant implications for conservation strategies in the face of environmental change. Cospeciation events are consistently outnumbered by non-cospeciation events, such as host-switch, duplication, and association losses, along with the plant-pollinator codiversification in six classical specialized pollination systems. It supports a more dynamic and diffuse paradigm of plant-pollinator codiversification. image
