Since then, more than 2000 Española tortoises bred in captivity have been returned to the island. All of them were brought to the breeding centre, along with a few specimens returned from zoos. The Española Island species was reduced to just 15 members in the 1970s. The Galapagos National Park Service has had great success with captive breeding of tortoises before. Another 63 are thought to have Floreana ancestry, but none appear to descend from Pinta.Ĭonservation biologists have begun a captive breeding programme with 23 tortoises now housed at the breeding centre, with the aim of returning tortoises to Floreana Island. ![]() The specimen had to be both scientifically accurate and beautiful, true not just to the Pinta Island species but to the beloved individual, Lonesome George. They said his body would probably be embalmed to conserve him for future generations. Alternatively, the two may have had very recent purebred ancestry. When the Pinta Island tortoise arrived at the American Museum of Natural History in early 2013 to be preserved, Museum scientists and a master taxidermist faced a number of critical decisions. Galapagos National Park officials said that with Georges death, the Pinta tortoise subspecies has become extinct. Genetic tests suggested that two of the tortoises may be purebred Floreana tortoises – which might imply that the Floreana species is not actually extinct. They carried out blood tests on 144 individuals, then lifted 32 promising candidates onto a ship by helicopter and took them to a captive breeding centre on Santa Cruz Island. In 2015, scientists returned to Wolf volcano to look for more tortoises with Floreana and Pinta ancestry. 1835: Sailing on a New Scientist Discovery Tour ![]()
