Scientists have discivered that the two giant tortoise populations on the Santa Cruz island are genetically different species. The researchers 'baptized' [as the press release states] the new species Chelonoidis donfaustoi, in honor of Fausto Llerena, the caretaker of Lonesome George, a male Pinta Island tortoise and the last known survivor of his species.
