Prehistoric Scratchpad
Bears adapted for cold climate, derived from Black Bears. The largest land predator and largest bear with the Kodiak. Hunt seals and spend most of their life on sea ice. Mitochondrial DNA research suggested they evolved only Late Pleistocene. New research from DNA from both parents show that it evolved much earlier, in the Middle Pleistocene, and that they had mixed with Brown Bears again more recently.
