DNA science is one that isn’t settled.
Every major new study creates new theories and often unsettles the previous DNA theories.
Also,politics and probably PCism is getting involved with the DNA science. That will probably screw up future DNA printouts
So, my African DNA was possibly polluted with Neanderthal DNA, and probably my snowflake Euro DNA. My snowflake Euro DNA, so far is mainly snowflake western Euro and the UK’s donations across those islands.
Every DNA linkage reports released by Ancestry have had a lot of changes.
The first big release 2 years ago, took away a lot of my Spanish and Iberian peninsula ancestors.
A big mystery to my siblings and cousins is the lack of Cherokee/any so called civilized tribal DNA in our reports. We have less than Fauxahontas. Yet we have written documentation re marriages, births and common law marriages showing over 150 documented so called Native Americans and zero DNA evidence.
In English it takes care of booze. Since the erstwhile "native american indians" had/have a deficiency in this enzyme we now know why they couldn't handle the white man's "fire water," alcohol.
All Oriental Asians have this deficiency,
Caucasian Asians: Indians, Pakistanis and Sri Lankans, have NO deficiency in this enzyme and can drink alcohol with no side effects.
They are also as HAIRY as Oriental Asians are NOT.
Its entirely possible to have no genetic heritage from an ancestor as recent as a great grandparent, let alone a Cherokee spouse or two back in the Appalachian frontier era. Far more of the legendary claims of Cherokee ancestry may have basis in fact than is currently believed, but there is no way to prove that via genetic testing currently.
