These extinct ‘terrible reptiles’ supported the evolving world proposed by Darwin, exemplified by the discovery of a fossil in Germany, only two... click to read more
7000 years of the peopling of present-day France revealed by paleogenomics
By accessing the genomes of past populations, researchers have revealed how migrations have been at the origin of major cultural changes for our societies. Some of them have shaped Europe's modern genetic heritage. In France, this type of study had only been carried out on... click to read more
Elpistostege: a fish with legs or a tetrapod with fins?
