Roots of Human Family Tree Are Shallow, Roots of the Human Family Tree Are Remarkably Shallow - All Alive Today Share 1 Common Ancestor - CBS News: "It also means that all of us have ancestors of every color and creed. Every Palestinian suicide bomber has Jews in his past. Every Sunni Muslim in Iraq is descended from at least one Shiite. And every Klansman's family has African roots.
How can this be?
It's simple math. Every person has two parents, four grandparents and eight great-grandparents. Keep doubling back through the generations _ 16, 32, 64, 128 _ and within a few hundred years you have thousands of ancestors.
It's nothing more than exponential growth combined with the facts of life. By the 15th century you've got a million ancestors. By the 13th you've got a billion. Sometime around the 9th century _ just 40 generations ago _ the number tops a trillion."
