However, the newer methods of genomics analyze thousands of sites in the genome, allowing the history of individual fragments of chromosomes to be traced back to particular populations (or species in the case of hybridization). With several suspected sightings and eight confirmed cases,[3] theories of how such hybrids might naturally occur have become more than hypothetical. However, their heads are a blend between a lean polar bear head and a broad grizzly bear head. Time will tell.. Washington Post Remembering when things got a little freaky at the National Zoo.
