I have 4 grandparents …

I have 8 greatgrandparents …

I have … wait, let’s make a quick calculation…

So 33 generations ago (which is about 33 x 25 = 825 years ago), I had more than 8.5 billion greatgreatgreat … great … people in my ancestor tree.

But … even now there are “only” 6.5 billion people in this world?
