Ancient mitogenomics clarifies radiation of extinct Mascarene giant tortoises (Cylindraspis spp.)
<p>The five extinct giant tortoises of the genus <i>Cylindraspis</i> belong to the most iconic species of the enigmatic fauna of the Mascarene Islands that went largely extinct after the discovery of the islands. To resolve the phylogeny and biogeography of <i>Cylindraspis</i>, we analysed a data set of 45 mitogenomes that includes all lineages of extant tortoises and eight near-complete sequences of all Mascarene species extracted from historic and subfossil material. <i>Cylindraspis </i>is an ancient lineage that diverged as early as the late Eocene. Diversification of <i>Cylindraspis</i> commenced in the mid-Oligocene, long before the formation of the Mascarene Islands. This rejects any notion suggesting that the group either arrived from nearby or distant continents over the course of the last millions of years or had even been translocated to the islands by humans. Instead, <i>Cylindraspis</i> likely originated on now submerged islands of the Réunion Hotspot and utilized these to island hop to reach the Mascarenes. The final diversification took place both before and after the arrival on the Mascarenes. With <i>Cylindraspis</i> a deeply divergent clade of tortoises became extinct that evolved long before the dodo or the Rodrigues solitaire, two other charismatic species of the lost Mascarene fauna.</p>

Figure 2 - Distribution of the number of native species of Croton in the Western Indian Ocean Region. There are 123 native species overall in the region, with 114 native to Madagascar; one of them (C. adenophorus) is shared with Mayotte, and the single species in the Union of the Comoros (C. humblotii) also occurs on Mayotte. The species on Mauritius and Reunion only occur there. The map of Madagascar shows how many species occur in each of the six former provinces (there are varying levels of overlap between provinces; see text for details).
