Abstract Major ecological transitions are thought to fuel evolutionary radiations, but whether they contingent on the evolution of certain traits is unclear. We show that rapid transition anglerfishes into pelagic habitats during a period major global warming coincided with origins sexual parasitism, in which male temporarily attach or permanently fuse females mate. A phylogenomic reconstruction history provides strong inference for convergent permanently-fusing deep-sea and their degenerate immune genes. Our results support parasitism was enabled by degeneration adaptive immunity ancestral size dimorphism. The combination these facilitated novel ecologies available deep open oceans after evolving from benthic ancestors. These how seemingly unrelated physiological reproductive interact synergistically drive radiation environments.

Oceans blanket more than two-thirds of Earth’s surface, yet marine biodiversity is disproportionately concentrated in coral reefs. Investigating the origins this exceptional diversity crucial for predicting how reefs will respond to anthropogenic disturbances. Here, we use a genome-scale dataset reconstruct evolutionary history wrasses and parrotfishes ( Labridae ), which rank among most species-rich ecologically diverse lineages reef fishes. We show that major labrid clades experienced pulses innovation accelerated diversification during Miocene approximately 20 15 million years ago origin no single phenotypic trait can explain. These results draw parallels histories many after mass extinctions corroborate recent fossil evidence an Early extinction event oceanic vertebrates changes faunal composition. Our data provide genomic reassembly faunas.

Extremophiles survive in environments that are considered uninhabitable for most living things. The evolution of extremophiles is great interest because how they may have contributed to the assembly ecosystems, yet evolutionary dynamics drive extremophile remain obscure. Here, we investigate Zoarcoidea , a lineage over 300 species fishes colonized both poles, deep sea, and hydrothermal vents. We show pulse habitat invasion occurred across 20 different zoarcoid lineages within last 8 million years, far after origin their prototypical innovation surviving cold water: type III antifreeze protein. Instead, secondary burst anatomical, physiological life history traits handful founder events extreme ecosystems appear propelled diversification. These results decentralize role changes organismal biology shaping radiations provide clear example combination ancient adaptations recent contingency shapes origination challenging habitats.
