How is it possible to have so many different races and ethnicities if we all allegedly came from Adam and Eve? How is it conceivable to have 4 different blood types (A, B, AB, and O) along with 2 different Rh values (positive and negative) from two people of origin? Even if you look at Darwin’s Theory of Evolution, there wasn’t enough time for genetic mutation or evolution of the species to create such different diversity amongst our population.
