ALL mankind descended from the first human pair, Adam and Eve. (Ge 1:28; 3:20; 5:1, 2) After the Flood, earth’s new population, including all the races and national groups on earth today, descended from Noah through his three sons and their wives, who were survivors of that global Deluge. Thus, after listing 70 offspring of the sons of Noah, the Genesis account says: “From these the nations were spread about in the earth.”​—Ge 10:32.
