英文摘要	The escalation hypothesis posits that predation by increasingly powerful and metabolically active carnivores has been a major driver of metazoan evolution.We test a key tenet of this hypothesis by analyzing predatory drill holes in fossil marine shells, which provide a ∼500-million-year record of individual predator-prey interactions.We show that drill-hole size is a robust predictor of body size among modern drilling predators and that drill-hole size (and thus inferred predator size and power) rose substantially from the Ordovician to the Quaternary period, whereas the size of drilled prey remained stable.Together, these trends indicate a directional increase in predator-prey size ratios.We hypothesize that increasing predator-prey size ratios reflect increases in prey abundance, prey nutrient content, and predation among predators.
