Lonesome George - or El Solitario Jorge - was a tortoise who lived on Pinta Island in the Galapogos. Thought to have been born around 1910, he was the last of his species to exist. When he died in 2012, aged around 100, his species (technically sub-species Chelonoidis nigra abingdoni) became extinct :(

When he was alive, they tried to mate him... but he did NOT have a successful sex life! Possibly because he had never been around females. All tortoises are solitary, but he was more solitary than most!!! The researchers even tried to teach him some 'moves' to help him out, but it never worked.

BUT... His DNA might not be extinct after all! On another island in the group, Floreana Island, a young female tortoise was found to have a high proportion of DNA similar to George. She is not an offspring of George... but her presence suggests at least one other purebreed Chelonoidis nigra abingdoni is out there!

Interesting!

Cell samples were taken from Lonesome George and frozen so by taking eggs from this female they might very well be able to artificially re-introduce the species.

No hope for such a possibility for the northern white rhino. ONly two survivirs, both females.

" The world's last surviving male has died after months of poor health, his carers say.Sudan, who was 45, lived at the Ol Pejeta Conservancy in Kenya. He was put to sleep on Monday after age-related complications worsened significantly.
His death leaves only two females - his daughter and granddaughter - of the subspecies alive in the world."
