Evolution of Polar Bears The observed fossil transitions that inform our knowledge of Polar Bear speciation are very well documented. Bear fossils change through time: generally‚ when examining the fossil record‚ successively deeper levels of sediments or sedimentary rocks yield successively older fossils.
