Back in May of 2008, a team of researchers at the University of Melbourne took a gene from the extinct Tasmanian tiger and applied it to a mouse embryo.
The gene expressed itself in the developing mouse; the gene worked.
Researchers insist that this study will not resurrect any extinct species in the near future, if ever. But, with the constant explosions in technology and the new ground breaking discoveries that keep happening in biology -- we all might be in for quite a surprise one day.
