4 p.[EN]The recent unexpected discovery that living Cycadales are not Jurassic-Cretaceous (200–65 Mya) relicts, as all their extant genera began to diversify during the Late Miocene (12 Mya), has challenged a classical evolutionary myth. This brief note shows how this finding may also provide new clues on the shaping of the high tropical biodiversity.[ES]El reciente e inesperado descubrimiento de que las Cycadales actuales no son relictos Jurásico-Cretácicos (200-65 Mya), ya que todos sus géneros iniciaron su diversificación durante el Mioceno Tardío (12 Mya), ha puesto en entredicho un mito evolutivo clásico. En esta nota se expone como este hallazgo puede, además, proporcionar nuevas pistas sobre el origen de la elevada biodiversidad tropical.Funding has been provided by projects CGL2009-07069/BOS (Ministry of Science and Innovation) and BIOCON 08-031 (BBVA Foundation).Peer reviewe
