The geographic distributions of living and fossil primates indicate that this clade has repeatedly engaged in "sweepstakes dispersal" across marine barriers. As its name suggests, sweepstakes dispersal is supposed to be extremely rare and more or less random, making it difficult or even impossible to study scientifically. New data show that certain taxa of primates and other mammals have repeatedly "won" the dispersal lottery, especially at certain critical times of Earth history. This seminar employs these data to try to constrain what has always been viewed as a random process.
Le CR2P est un laboratoire entièrement dédié à la paléontologie.Il a pour objectif d'élucider la structure des relations de parenté et l'histoire du vivant au travers du registre fossile et des environnements du passé. Il est sous la triple tutelle du Muséum national d'Histoire naturelle (MNHN), de Sorbonne Université et du CNRS (INEE).
