Common Ancestor

LINK - This article talks about a common ancestor without offering a solution to the problem. If the author would just read the Bible, he would have the answer. I'm not even going to go back to "Adam" to solve this one. Noah, his wife, his 3 sons, and their wives were the only persons left on earth after the Flood. Therefore, the common ancestor would be Noah. (Of course, Noah can trace his ancestry to Adam.) The date recognized by most Bible scholars (at least Evangelical or conservative Bible scholars) falls withing the mathematical probability of the common ancestor as recognized in this article.
