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 BC on
an island off the coast of Siberia, where researchers uncovered 29 fossilized
woolly mammooth 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 six
feet tall at the shoulder, compared with ten 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 reason for this isolated group's belated disappearance.
