英文摘要	A decline in diversity from the equator to the poles is a common feature of Earth's biodiversity. Here, we examine body shape diversity in marine fishes across latitudes and explore the role of time and evolutionary rate in explaining the diversity gradient. Marine fishes' occupation of upper latitude environments has increased substantially over the last 80 million years. Fishes in the highest latitudes exhibit twice the rate of body shape evolution and one and a third times the disparity compared to equatorial latitudes. The faster evolution of body shape may be a response to increased ecological opportunity in polar and subpolar oceans due to (1) the evolution of antifreeze proteins allowing certain lineages to invade regions of cold water, (2) environmental disturbances driven by cyclical warming and cooling in high latitudes, and (3) rapid transitions across depth gradients. Our results add to growing evidence that evolutionary rates are often faster at temperate, not tropical, latitudes. Regions of Earth that are closer to the tropics tend to have more biodiversity than regions that are closer to the poles. We explored this pattern by examining body shape diversity across marine fishes, a group of aquatic animals that span latitudes from tropical waters at the equator to polar and subpolar oceans at the poles. We found that modern marine fishes moved into polar and subpolar oceans relatively recently, with the invasion of these oceans occurring within the last 80 million years. Contrary to the common pattern, marine fishes' body shape diversity is higher in high temperate regions than in tropical regions. Underlying this pattern, we find that polar and subpolar marine fishes evolve body shapes faster than species in the tropics. The more rapid evolution of body shape in temperate species may be due to the evolution of unique antifreeze proteins that have allowed polar and subpolar fishes to exist in icy seawater, cyclical changes in the climate at polar and subpolar latitudes, and a higher rate of transition across depth habitats. Despite the typical biodiversity pattern, our results add to growing evidence that evolutionary rates are often faster at temperate, not tropical, latitudes.
