In their words
Shapiro reports that brown bears in North America carry polar bear ancestry from interbreeding about 20,000 years ago, but polar bears show no brown bear ancestry, likely because hybrids cannot hunt seals.
“if you have brown bear ancestry, you don't have perfectly white fur and you cannot successfully hunt seals”
