This is a Speculative Evolution of a Polar Bear. Since the habitats of polar bears have been shrinking, the future will possibly have less of the icy, cold world of the polar bear. So in the future, polar bears could possibly be forced from their home and onto human territories, which has been happening today. However, the polar bears in the future have been so adapted to humans that they have evolved into a smaller, more city dwelling species. Future Polar Bears would probably have more browner fur since they don't need to camouflage in the ice and now in the human settlements, a bigger nose to find scraps and leftovers left by humans, no swimming capabilities, a mid-stocky build to look much bigger to other scavengers such as foxes and to also be strong enough to break certain items, and a fuzzy underside to provide warmth to their cubs and to keep warm so they don't get cold, but it's significantly less fur than today's polar bear since there isn't much cool weather today's polar bears can deal with.
Some cool thing I've been thinking of :)
