The grizzly bear DNA study that Senator John McCain often ridiculed out of ignorance has shown that there are many more grizzly bears in the Northern Continental Divide Ecosystem than previously estimated. The technique is effective enough that individual bears can be recognized and the parentage of the bears can also be determined.

The researchers estimate that there are about 765 grizzlies in the area which is 2 1/2 times higher than previously thought.

Industry groups like this information because they want grizzlies to be taken off the Endangered Species List. They are hoping for eased restrictions on logging, mining and other activities.
