They are commonly created in fish hatcheries and stocked in lakes and rivers for sport-fishing. But neither is wrong. They were originally created by biologist Warwick E. Kerr in Brazil when he was attempting to breed a strain of bees that would produce more honey and be better adapted to tropical climates. Rather than grolar bears taking over the Arctic, the real risk is that what we know as polar bears will simply be absorbed into a tide of grizzly DNA through successive crossbreeding events. The northern minke whale diverged from the southern minke some five million years ago roughly when what became the human lineage diverged from that of chimpanzees.

Oil spills and agricultural runoff, each linked to fish hybridization, are not uncommon. Example: in the northerly Norwegian islands of Svalbard, there is a significant polar bear population. It is a rare animal to see, especially in the wild, but many people have encountered them over the past several decades. Fish and Wildlife Service and sent to the Alaska Zoo after showing signs of being comfortable around . Over the years that followed, the genetic exchange pulled the mean beak size of the two parental species which remained distinct closer together. Many people in North America use the common name "grizzly bear" to refer to the smaller and lighter-colored bear that occurs in interior areas and the term "brown bear" to refer to the larger and typically darker-colored bear in coastal areas.
