(Martin-Luther-Universität Halle-Wittenberg) The evolution of giant tortoise might not be linked to islands, as had been previously thought. In a first-of-its-kind study, researchers from Argentina and Germany present the most comprehensive family tree of extinct and extant tortoises so far. Analysing genetic and osteological data from living species and fossil tortoise they rewrite the evolution of tortoise: Giant size evolved on multiple occasions on the mainland. The findings will appear in the next issue of "Cladistics".
