As the effects of climate change worsen, we may start to see more and more grizzly and polar bear hybrids.
while the heat pushes grizzly bears north.
More often than not, two animals come in contact while hunting, for example at whale carcass sites, and interact, , an associate professor of biological sciences at Tennessee's Vanderbilt University. The result? This breeding act is creating hybrid"pizzly bears," sometimes called grolar bears, and according to some scientists, the pizzlies could be here to stay.
Since 2006, the effects of climate change have worsened and sightings of pizzlies have become more common. For example, a 2017 research published in the journalscientists recorded eight pizzlies that were the offspring of a female polar bear who mated with two different grizzly bears. Furthermore, since the two animals only diverged around 500,000 to 600,000 years ago, their offspring can reproduce. One study has found a hybrid that was born from a pizzly mating with a grizzly.
Scientists are studying how well these hybrids are suited for life in the wild."Usually hybrids aren't better suited to their environments than their parents, but there is a possibility that these hybrids might be able to forage for a broader range of food sources,"
