A believer asked me that question this week. This believer (first name of Al) referred the unbeliever to the Tower of Babel. When God confused the languages, people separated and moved apart. To me, it seems that the differences came about by heredity. Dictionary meaning=..."(1.) The process by which characteristics are passed on genetically from an animal or plant to its offspring. (2). all the characteristics passed on in this way." I looked up Gregor Mendel in the dictionary. It shows "1822-1884, Austrian monk and botanist whose experiments in heredity were the foundation for the science of genetics." Did the "whites, the yellows, the reds, the blacks" [and others] all come from Adam and Eve? I believe that the answer is "yes." The next question is "how did the differences develop?" I need a simple answer, please, to pass on to my brother "Al." The Bible may just assume the differences and may not explain it to us. If this is the case, then could you please tell how "genetics" worked for the different skin color, different facial features, etc. Thanks for your help. "mr. messy."
