I took lessons in genetics when working on my anthropology degrees, and I'm gonna tell you again, namely that you simply do not know what you are talking about here.
You have an extremely short memory, or so it appears, as we were discussing this last week. Remember, in terms of "variations" when I used the women at the tomb example, whereas you finally admitted that the accounts do not exactly match? You responded that different people "witnessed" different things, thus reporting what they heard, which was not the same. You can't remember this conversation?
