Reproductive innovation enabled radiation in the deep sea during an ecological crisis

Major ecological transitions are thought to fuel diversification, but whether they are contingent on the evolution of certain traits called key innovations is unclear. Key innovations are routinely invoked to explain how lineages rapidly exploit new ecological opportunities . However, investigations of key innovations often focus on single traits rather than considering trait combinations that collectively produce effects of interest . Here, we investigate the evolution of synergistic trait interactions in anglerfishes, which include one of the most species-rich vertebrate clades in the bathypelagic, or ‘midnight,’ zone of the deep sea: Ceratioidea. Ceratioids are the only vertebrates that possess sexual parasitism, wherein males temporarily attach or permanently fuse to females to mate. We show that the rapid transition of ancestrally benthic anglerfishes into pelagic habitats occurred during a period of major global warming 50-35 million years ago. This transition coincided with the o..., The main text of the manuscript describes this., , # Reproductive innovation enabled radiation in the deep sea during an ecological crisis
