Ancestry of Polar Bears Traced to Ireland
July 7, 2011
An international team of scientists has discovered that the female ancestor of all living polar bears was a brown bear that lived in the vicinity of present-day Britain and Ireland just prior to the peak of the last ice age--20,000 to 50,000 years ago. The research is expected to help guide future conservation efforts for polar bears, which are listed as threatened under the Endangered Species Act.
