Scientists will bring back woolly mammoths. They all died 4,000 years ago. It is like something from the movie Jurassic Park. Scientists will use mammoth DNA to clone the giant animal. A mammoth hasn't walked on the earth since the Ice Age. The goal is to create baby mammoths in the next four to six years.

A businessman gave $15 million for the research. He wants to return the mammoth to its Arctic home. He thinks the research will make our health care better. He said the project was like the Apollo missions to the moon. They led to technology like GPS. The businessman thinks the mammoth research will improve our lives.
