Tortoise who saved species by fathering hundreds returns to Galapagos

A tortoise who helped save his species from extinction by having hundreds of children will be released into his homeland after spending eight decades away, conservation authorities have said.Diego earned a reputation for having lots of sex during a captive breeding scheme for giant tortoises in the Galapagos Islands, and the 100-year-old has now reportedly fathered over 800 children.
