As I’m sure I’ve stated many times before the “science” is flawed. We can’t test it outside its base assumptions. Genetic markers are not 100% (which seems to have been missed by many here)
I don’t think you meant to say this specifically in the way you said it and I
think I know what you meant to say so if my presumption is wrong I hope you’ll correct me.
I believe you meant to say “Those who discredit the Book of Mormon are deriving fallacious conclusions FROM the DNA evidence available” not “The science is flawed / DNA markers are not 100%”. If this is indeed what you meant to say, then I’m inclined to agree.
“Absence of evidence is not evidence of absence” after all.
This brings us back to the LDS favorite of “appeals to possibility”. It is indeed possible that those who left Judaea to come to the Americas just so happened to be a part of the 0.8% (almost all of whom have very little Jewish maternal ancestry) or so of the Jewish community that do not have 4 very uniquely Jewish haplotypes. If this were the case, then obviously no one in pre-Columbian America would exhibit these and the data would be expected to appear exactly as it does today.
The probability of this however is extremely small, howbeit possible (then again ANYTHING is possible).
For all intensive purposes most would conclude that this evidence “disproves” the validity of the Book of Mormon, though in a strictly empirical sense this is not true.
In all
technicality the only conclusion one can draw is:
“There is no evidence that a Jewish population lived in pre-Columbian America”
NOT
“There is evidence that Jewish populations didn’t live in pre-Columbian America”.
As an empiricist myself, I will run with the probability and tentatively conclude (for myself) that there were no pre-Columbian Jewish-American populations simply because there is not a shred of evidence that implies their existence.
Now I must point out though that the Book of Mormon is stuck in a “catch 22” predicament.
On the one hand, there is strong DNA evidence that
suggests that the BOM characters are fictional (since it is highly improbable that those certain “Jews” who sailed to the Americas all lacked their ethnic haplotypes.
On the other hand (assuming that those who sailed to the Americas indeed were real AND lacked the haplotypes) then that would indicate that they were actually NOT JEWS!!!
The
religious implications of this as one can see are just as damning, for these voyages are alleged to occur prior to Jesus and thus when the Mosaic law was practiced (including a Jewish identity relying SOLELY on the mother from whom mtDNA is bestowed to a child).
