Tasmanian tiger DNA 'resurrected'


A fragment of DNA from the Tasmanian tiger has been brought back to life.

Australian scientists extracted genetic material from a 100-year-old museum specimen, and put it into a mouse embryo to study how it worked.

"As more and more species of animals become extinct, we are continuing to lose critical knowledge of gene function and its potential," he said.

The Tasmanian tiger was hunted to extinction in the wild in the early 1900s.

Some researchers think the method could help reveal the function of genes in species such as the Neanderthals or mammoths.
