Evolutionary flexibility to gain or lose tooth complexity sparks fish diversification

Nature, Published online: 26 February 2025; doi:10.1038/d41586-025-00541-1Why are some species more likely to diversify than others? For the largest group of vertebrates, ray-finned fishes, the ability to evolve by transitioning back and forth between simple and complex teeth fuelled their diversification.
