This is a question about Genealogical Adam and Eve that may well be answered in the book (I confess I haven’t read it yet). So please feel free to reply with “This has already been addressed in the book.” I plan to read it this Christmas break when I have a free few days.
The question is this:
Adam and Eve may be the genealogical ancestors for all of humanity today, but they couldn’t have been the ancestors of all of humanity when they were alive. How many generations on average would it take before Adam and Eve were genealogical ancestors of all humans?
