Scientists propose grizzly genetic research Researchers are proposing genetic testing to determine whether grizzly bears in the Yellowstone region interbreed with grizzlies from elsewhere. Scientists with the U.S. Geological Survey proposed the study Wednesday in a meeting of the Interagency Grizzly Bear Committee in West Yellowstone, Mont. Federal judges in Montana and Idaho are presiding over three separate lawsuits challenging a decision by the U.S. Fish and Wildlife Service in April to remove grizzlies from the endangered species list. One argument against delisting is the population's lack of genetic diversity. Some say that could threaten the long-term health of bears in the ecosystem. Scientists say grizzlies from Canada or northwest Montana must breed with bears in the Yellowstone ecosystem at least once every generation to maintain the genetic diversity of the Yellowstone population....Our nation's scientists are saying Drill Bear Drill!
