Life After Extinction: Is There a Tiger in the Mouse?

From Scientific American:

For the first time, researchers have inserted the genetic material of an extinct animal into a living one. The finding shows how lost information about species from the past can be retrieved, and also provides a glimpse into how long-gone creatures may someday get a second chance at life."Now that we've shown you can do this, it opens up the floodgates for all kinds of extinct species," says Andrew Pask, a fellow in zoology at the University of Melbourne in Australia and lead author of a paper published in the online journal PLoS ONE. The gene that the scientists activated in mouse fetuses contained instructions that helped produce cartilage in the rodent's developing skeleton.
