We show that diversification pulses are a recurrent feature of equid evolution but that these pulses are not correlated with rapid bursts in phenotypic evolution. Instead, rapid cladogenesis seems repeatedly associated with extrinsic factors that relaxed diversity bounds, such as increasing productivity and geographic dispersals into the Old World. This evidence suggests that diversity dynamics in Equinae were controlled mainly by ecological limits under diversity dependence rather than rapid ecomorphological differentiation.engjournal articlehttp://science.sciencemag.org/content/355/6325/627http://www.sciencemag.orgrestricted access56Morphology (Animals) ResearchHorses - Genetic aspectsAnimal morphology - Research Horses -- Genetic aspectsPaleontología2416 Paleontología
