I don't know my great-grandfather's name, and I gather that you don't either, so we have a handicap in that we can't cull out Y-DNA matches by surname. This means that the ABC Islands brown bears share more DNA with polar bear females than they do with polar bear males, Shapiro said. The team discusses the legend of the largest bear ever seen and more. To their surprise, they found that brown bears and cave bears did more than share habitat, all those thousands of years ago — the two very different species also interbred.

Shapiro's team found that polar bears are a remarkably homogeneous species with no evidence of brown bear ancestry, whereas the ABC Islands brown bears show clear evidence of polar bear ancestry. Shapiro and her colleagues analyzed genome-wide DNA sequence data from seven polar bears, an ABC Islands brown bear, a mainland Alaskan brown bear, and a black bear. I am 1/4 Eastern Band Cherokee.

And grizzlies walk like men, placing their full foot on the ground with each stride. But a 2011 study of mitochondrial DNA from extinct Irish brown bears showed an even closer match to polar bears and suggested that polar bears got their mitochondrial DNA from hybridization with Irish bears. Since then, the two species have met and interbred several times, and today, brown bears (also referred to as grizzly bears) still retain some of this ancient polar bear DNA, and vice-versa. We can now explain it, and instead of the convoluted history some have proposed, it's a very simple story," said coauthor Beth Shapiro, associate professor of ecology and evolutionary biology at UC Santa Cruz.
