Tens of thousands of fossils embedded in amber show that termites have always been termites. Ants have always been ants, frogs have always been frogs, snakes have always been snakes, butterflies have always been butterflies. In short, living things have always existed in the forms they first displayed when they first came into the world, with the same features. There is no difference between living things preserved in amber millions of years ago and their present day counterparts.
