Alright. The Lamanites are the principle ancestors of the American Indians. I believe that.
Now please make a coherent point, if you have one.
If any Jewish DNA was inserted into the DNA stream of any of the (North/South, or Central) American Indian populations, ... that DNA should still show up.
To-date, not one trace of Jewish DNA has been found in these populations, despite extensive studies.
DNA doen't just disappear.
Coincidentally, ... there has also not been found ... any trace of Jewish culture, linguistics, arti-facts.
To-date, there has not been found any trace of any Jewish heritage among the Native American peoples in any way.
That DNA must be some bad stuff if it can tell me that I had a single ancestor 3000 years ago that came from X country...
I don't know enough about DNA to argue it.
