Ever wonder why polar bears love to dance gigs and always call into work sick the day after St. Patrick's day?
Well…. it turns out the Arctic's dwindling population of polar bears all descend from a single mama brown bear which lived 20,000 to 50,000 years ago in present-day Ireland.
A study recently released said DNA samples from the great white carnivores — taken from across their entire range in Russia, Canada, Greenland, Norway and Alaska — revealed that every individual's lineage could be traced back to this Irish forebear.
Interbreeding may have helped polar bears survive climate change events in the past — offering some hope for the future.
