Incredible Technology: How to Bring Extinct Animals Back to Life

 

This photo shows a museum worker inspecting a replica of a woolly mammoth (Mammuthus primigenius), a relative of modern elephants that went extinct 3,000 to 10,000 years ago. Scientists in Russia and South Korea have embarked on an ambitious project to try to create a living specimen using the DNA-storing nucleus of a preserved mammoth cell and an Asian elephant egg.

The passenger pigeon, the dodo and the woolly mammoth are just a few of the species wiped off the Earth by changing environments and human activities.

Now, advances in biotechnology could enable scientists to bring extinct animals back from the grave. But critics argue the practice would only hinder conservation efforts, by resurrecting creatures that could not survive in the wild.
