A team of Russian scientists has challenged the theory that the

woolly

mammoths became

extinct 10,000 years ago at the end of the Ice Age. The scientists have reported that the

beasts may have survived until 2000 B.C. on an island off the coast of Siberia, where

researchers uncovered 29 fossilized woolly mammoth teeth ranging in age from 4,000 to

7,000 years. The question to be asked now is, how did these prehistoric pachyderms survive

in their island environment? One possibility is that they adapted to their confined

surroundings by decreasing their bulk. This theory is based on their smaller tooth size, which

has led scientists to believe that they were only 6 feet tall at the shoulder compared with 10

feet of their full-sized

counterpart. But would this be enough to enable them to survive

thousands of years beyond that of other mammoths? Researchers are still working to

uncover the reasons for this isolated group's belated disappearance.
