I hope no one thinks that I would try to sneak in some kind of backwards reasoning for Adam and Eve. When I learned about it, I was just shocked that scientist can link our genes back to a single man and woman. Not saying that the theory is that they were the only man and woman. And that they even lived together. However this article http://www.nature.com/news/genetic-adam-...me-1.13478 says that they could have lived concurrently. And Its interesting to me that Adam (according to the article) more than likely lived farther back than Eve. The scientific Adam and Eve that is. Could someone just explain how at one point the genes were only from a single man and a single woman? I have read the wiki pages but they're just above me
