Here we go again, global warming being pointed to as one answer. I am sorry, I am not buying it, and I am glad other scientist are not just jumping on the bandwagon.
I am sure many of you remember this story. http://www.slate.com/id/2253332/?Gt1=38002
Some scientists believe that global warming could cause the hybridization of many arctic animals (http://www.vancouversun.com/travel/Warming+Arctic+will+give+rise+mammal+hybrids+Biolo gist/2961475/story.html), particularly marine mammals. The thinking goes that as Arctic sea ice melts, closely related species in the North Pacific and North Atlantic will come into contact and interbreed. In the case of polar bears, loss of habitat could drive them to land, where they may come into contact with grizzlies. Other scientists, however, aren't convinced that climate change is the trigger for the hybrid bears.
