It is said that evolution always moves forward and that it can not move backward. An amphibian, once it is an amphibian, can not go back to being a fish. Man can not return to being an ape. Species go from one form to another but always more complex, always more specialized. However, recently I have been wondering if this is true and if not, if we may be the perfect example of evolution reversing and not just one step, but several huge strides.
