Famed Galapagos tortoise Lonesome George dies

The giant Galapagos Islands tortoise dubbed Lonesome George, whose failed efforts to produce offspring made him a symbol of disappearing species, was found dead on Sunday, officials at the Galapagos National Park announced.

Lonesome George was believed to be the last living member of the Pinta Island subspecies and had become an ambassador of sorts for the islands off Ecuador's coast, whose unique flora and fauna helped inspire Charles Darwin's ideas on evolution.

The tortoise's age was not known, but scientists believed it was about 100, not especially old for giant tortoises, who can live well over a century. Scientists had expectedthe tortoiseto live another few decades at least.

Various mates had been provided for Lonesome George afterit was found in 1972 in what proved unsuccessful attempts to keepthe subspecies alive.

Itlived at a tortoise breeding centre on the archipelago's island of Santa Cruz.It was found Sunday morning inits pen byits longtime keeper, Fausto Llerena, the park said in a statement.

Attempts were initially made to mate Lonesome George with two female tortoises from Wolf Volcano. But the eggs they produced were infertile.

Two females from Spanish Island's tortoise population, the species most closely related to Pinta tortoises, were placed withGeorge last year.

The park said the cause of death would be investigated.

The Galapagos' giant tortoise population was decimated after the arrival of humans, but a recovery program run by the park and the Charles Darwin Foundation has increased the overall population from 3,000 in 1974 to 20,000 today.
