Philadelphia Inquirer: Between polar bears, grizzlies, a sharing of the genes in Ireland

An article in the Philadelphia Inquirer reports on new DNA evidence that shows that polar bears carry genetic material that links them to the brown bears that roamed Ireland 30,000 years ago, and quotes UB biologist Charlotte Lindqvist. Scientists should be careful how they interpret these latest findings, she said. An article also appeared in the Christian Science Monitor and on CBS News.
