Phylogeny

The raccoon and bear families are believed to have diverged about 30 million years ago and around 13 million years ago the spectacled bear split from the other ursine bear. The 6 distinct ursine species originated some 6 million years ago. The brown bear and polar bear diverged from a common ancestor around 2 million years ago and crosses between the two species produce fertile hybrids. They only lost their Brown Bear molars between 10 and 20 thousand years ago.
