UF: Extinct tortoise yields oldest tropical DNA

An extinct tortoise species that accidentally tumbled into a water-filled limestone sinkhole in the Bahamas about 1,000 years ago has finally made its way out, with much of its DNA intact.

As the first sample of ancient DNA retrieved from an extinct tropical species, this genetic material could help provide insights into the history of the Caribbean tropics and the reptiles that dominated them, said University of Florida ornithologist David Steadman. It could also offer clues to the region’s future, as the tropics undergo significant transformation due to climate change.
