This handout picture received on July 31, 2017 by the Universite Paris-Sud shows a 3D model of an ancestral flower reconstructed by a new study, showing both female (carpels) and male (stamens) parts, and multiple whorls (concentric cycles) of petal-like organs, in sets of threes. The first flower to appear on the path of plant evolution, during the time of the dinosaurs, was bisexual with petal-like organs arranged in concentric circles, researchers said on July 31, 2017. / AFP PHOTO / Universite Paris-Sud / Herve SAUQUET AND Jurg SCHONENBERGER / RESTRICTED TO EDITORIAL USE - MANDATORY CREDIT "AFP PHOTO / UNIVERSITE PARIS-SUD / HERVE SAUQUET & JURG SCHONENBERGER" - NO MARKETING NO ADVERTISING CAMPAIGNS - DISTRIBUTED AS A SERVICE TO CLIENTS
