Where do flowers come from - Shedding light on Darwin's "abominable mystery". The mystery that is the origin of flowering plants has been partially solved thanks to a team from the "Laboratoire de Physiologie Cellulaire et Végétale" (CNRS/Inra/CEA/Université Grenoble Alpes), in collaboration with the laboratory "Reproduction et Développement des Plantes" (CNRS/ENS Lyon/Inra/Université Claude Bernard Lyon 1) and Kew Gardens (UK). Their discovery, published in the Terrestrial flora is today dominated by flowering plants. They provide our food and contribute color to the plant world. But they have not always existed. While plants colonized the land over 400 million years ago, flowering plants appeared only 150 million years ago. They were directly preceded by a group known as the gymnosperms, whose mode of reproduction is more rudimentary and whose modern-day representatives include conifers.
