Can Genetics Solve the Mystery of the Lost Ten Tribes of Israel?

Geneticists will always need to rely on non-genetic evidence to make any historical sense of the data—written texts, oral traditions, and interviews with people about who they are and where their ancestors come from. Without such evidence it is impossible to turn the testimony of DNA into a coherent account of the past, and that process means that there will also always be some degree of imagination involved in the construction of genetic history, just as is the case for historical accounts based on ancient texts or archaeological finds.

You make a very persuasive case for being cautious in these genetic matters. I was wondering if the only place to look for the Lost Tribes is among the modern Samaritans. If the Bible account is anywhere near the literal truth there was a huge population transfer between the Israelite Kingdom and the other Assyrian dominions way back then, such that there must be many Israelite genes in Iraq and many genes from a mixed multitude in the area of the old Northern Kingdom, subject to much churning over intervening centuries. Would the geneticists have any way of tracing all that after all this time?
It seems that after a few centuries there were no political or religious groups in Iraq and suchlike, not even families, claiming Lost Tribe status. Perhaps that indicates rapid loss of genetic identity?

Prof. Weitzman,
Thank you very much for this article. I had been wondering for years if any biblical scholar was going to respond to the claims of Karl Skorecki and his co-researchers. I am glad to learn that you have a more extended discussion in a book.

To answer Martin's query, there are certainly other peoples who believe themselves to be descendants of the lost tribes of ancient Israel.

Another famous case studied by geneticists, though involving the tribe of Judah rather than the ten lost tribes, involves the Lemba people in southern Africa, some of whom believe themselves descendants of exiles from ancient Judah.

But I don't know of any other people where we can trace this belief as far back in time as we can for the Samaritans, so they really do represent an important test-case. We will have to see how the genetics research develops, but some skepticism seems appropriate.

My thanks for the question and to Dr Avalos for his kind note.

I have now bought and read the most relevant and some other passages of your interesting book and have done a little wider reading, some of it only on Wikipedia levels, but including Raphael Falk in Frontiers in Genetics 2015 'Genetic markers cannot determine Jewish descent' and noting Tofarelli (same journal previous year) about the difficulty of finding 'markers ...of Bible tales' by these means.
The story as presented here, even more in the book than in the article I think, is a gentle parable of the conflict - hardly a conflict because the scientists aren't really interested - between scientific modernism and literary postmodernism. But it seems to me that the real story is a much darker one in which research which was either overconfidently conducted or overconfidently reported in a heated ideological atmosphere, one might say echo chamber. There was evidently much use of latest techniques, which implies an excellent funding stream, which is always in all contexts a well-known source of unbalanced or
overconfident thinking. No individual may be particularly responsible, as things move from the gentle buzz of laboratory computers to the excitement of the press release, for
the overconfidence. But still it is important, when the ideological atmosphere is crackling with so much thunder and lightning, to make highly explicit efforts to emphasise the continuing room for doubt and scepticism. Not to do so is irresponsible and dangerous, as it takes no postmodern verbal trickery to see.

First I’ll say that I enjoyed reading this article, it was rather well thought out. With that out of the way, it continues to amaze me that people don’t see what is staring them in the face, not just this author, who seems to be seeking and seeing more than most, but with humanity in general.

What do we go to and reckon with to have any kind of certain answers and true knowledge? Logic! What is “The One True God” that Moshe’s Torah spoke of in a time and in a language where they didn’t use the word “Logic” but called it YHWH? That’s correct class, Moshe’s Torah said that God was and is the true source of true knowledge (Logic), which is also why the Greek translation of the Torah (The Septuagint) said that God is “Logos” and it’s why even the Greek of John 1 in the Christian New Testament, where the KJV poorly translates that God is “the word”, says that God is “Logos” (Logic).

God is Logic, specifically the formless/incorporeal “Substance of Logic” that all forms of Logic such as math or yes even science must be coherent with in order to be objectively “logical”. The one who who makes x=x, by any of our arbitrary names like “Logic”, “God”, “Hashem/The Name” or even “The One Who Makes X=X” this one is the rational substance that has made (and makes) the universe be the universe be the universe, and who makes all of us be all of us.

If we want to find the common ancestor that we and all other concepts can trace our roots back to we MUST “reckon faithfully” (reason properly, objectively and honestly) with Logic, Avinu Malkeinu.

Once you know the beginning of the chain (Logic) and the end (you) you can again keep reckoning with Logic, properly, honestly and objectively (aka “in good faith”) and find whichever other intermediate ancestors you may desire to know more about.

Those who fail to reckon properly and who lose track of the objective truth because of subjective biases will hide the truth from themselves.

Do not to be led astray by your own heart but to reason with The One True God, the one who said “I will be what I will be” (Logic) for answers and true knowledge of good and evil.

The area referred to as the Holy Land has been continuously occupied by the same people since BCE. Those people currently are known as the Palestinians. BCE jews accurate history should note conversion out of judaism. Modern history also shows non-semitic people have converted to judaism.
