Extinct tortoise to be brought back to life

An extinct Galapagos tortoise species could walk again, scientists believe.

Researchers report finding relatives of Geochelone elephantopus alive and well. By cross-breeding these living tortoise, scientists might be able to re-create the extinct species - though it could take a century. "We might need three or four generations to do this," Gisella Caccone from Yale University in New Haven, US, stated. "But in theory it could be done, and I think it's pretty exciting to bring back from the dead a genome that we thought was gone."

The distribution of related tortoises between the islands was one of the pieces of evidence Charles Darwin used in formulating his theory of evolution. But of 15 known Galapagos species, four have since gone extinct - elephantopus less than two decades after Darwin visited the island.
