Farmers digging a field near Chelsea,Michigan,were surprised to uncover a nearly complete mammoth skeleton The mammoth once lived there about 12 ,000 years ago. The Ice Age bones raise a question about whether people or a changing climate killed the beasts.

Researcher Dan Fisher is from the University of Michigan. He believes that prehistoric people killed the newly found mammoth,and put what they didn't immediately eat in a freezing lake. Other scientists say they are not certain what killed the creature until the bones are examined for cut marks and other evidence.

There is little evidence that humans hunted mammoths,says Donald Grayson of the University of Washington. A paper notes that of 76 Ice Age mammal kill sites,only 12 in the whole of North America suggest human hunting. That suggests that over-hunting was not the primary cause of the extinction of the mammoth.

Climate might have been key to the disaster. As humans were moving onto the continent,the global climate was rapidly changing,moving from cold and dry to warm and wet.

This changing climate rapidly swept out the cool,dry grasslands that mammoths preferred. Combined with other (生态的) changes,such as the arrival of bison (野牛) from Europe and Asia and forests springing up here grasslands once spread,mammoths were driven out of their former living places. The very last of the mammoths on Wrangel Island off northern Siberia died out about 4 ,000 years ago.

Extinction is rarely the result of a single cause. Perhaps,as the Chelsea mammoth slowly tells its secrets,it will add a little more to the continuing discussion over life and death during the Ice Age.
