The turnover-pulse hypothesis, formulated by paleontologist Elisabeth Vrba, suggests that major changes to the climate or ecosystem often result in a period of rapid extinction and high turnover of new species (a "pulse") across multiple different lineages. Changes may include climate change, tectonic plate shifting, and catastrophes, among other things. It can be seen as an extension of the concept of evolutionary radiation from a single to a multi-clade context.

  • La hipótesis del pulso de cambio, formulada por la paleontóloga Elisabeth Vrba, sugiere que los cambios importantes en el clima o el ecosistema a menudo resultan en un período de rápida extinción y una alta aparición de nuevas especies (un "pulso") en múltiples linajes diferentes. Los cambios pueden incluir cambio climático, desplazamiento de placas tectónicas y catástrofes, entre otras cosas. ​ Puede verse como una extensión del concepto de radiación evolutiva de un contexto de un solo clado a uno de múltiples clados . ​ (es)

  • L'ipotesi dell'impulso di avvicendamento (turnover-pulse hypothesis), formulata dalla paleontologa Elisabeth Vrba, suggerisce che catastrofi o grandi cambiamenti dell'ecosistema spesso comportino un periodo di rapida estinzione e alto avvicendamento (turnover) di nuove specie attraverso più linee di discendenza. Può essere visto come un'estensione del concetto di radiazione evolutiva da un contesto singolo a uno a più cladi. (it)
