Evidence of Change in Bears
In the life of bears they change just as much as any organism does it can either be over millions of years or just one year in the life of a baby cub. Bears appeared around 30 to 40 million years ago during the Oligocene period. So let's begin with the basic changes of bears over their change in time.
Basic Change #1 :
Bears have these strong, sharp-edged teeth in which allows them to tear flesh of a prey when needing food. Or these can also be put to use when fighting a predator in need of a skill for protection.
