Found out La Femme and I had great grandfathers who lived on opposite sides of a fjord in Norway! Explains why we both like fish and stinky cheese so much, huh?

One way to tell if you have had recent Native American ancestry is through teeth. If yours are shovel or talon shaped or some modified in between version.





Another indicator is the Mongoloid spot in the lower back toward the base of the spine. It appears as a large bruise to many and is typical of people from east Asia and Native Americans.

I know the paranoid comrades see it differently but 23andme sharing their database with drug makers could result in yuge benefits for the rest of us.

Agree to the value, but this is countered by DMT's assertion of .gov/LEO access until such time that definitive regulation could be formulated and enacted (itself perpetuating the -arguable- big gov't rant) and probably more concerning to most, the potential for insurance companies to use the data to decline you coverage or adjust your premiums based on what you COULD develop.

Fascinating times ahead!

Dale, colour me un naif but despite the Supreme Court’s makeup I don’t see them allowing Big Brother access to that database. And I thought it is anonymous anyway?

Just use a fake name / account if you want to get your DNA results but are worried about conspiracy theory stuff.
And if insurance companies can and will use genetic testing info to set your rates, they're going to make you spit in a tube with someone watching before writing a polciy, they're not going to hack 23andme or whatever. Duh.
Not at all suggesting there's any compelling reason to get a test, but if you'd like to but you're paranoid for whatever reason, just take off your tinfoil hat and think for a minute, it's not that big a deal.

hey there say, jan... as to your quote:

Another indicator is the Mongoloid spot in the lower back toward the base of the spine. It appears as a large bruise to many and is typical of people from east Asia and Native Americans.

this is what me, and one sibling, were born with, in our family...
only 2, out of 8 kids... my gramma found a picture of a south american
indian woman, holding her baby-- with the same blue-blackish spot...

it really helped my mom, as, she had to clue, what on earth this was...

and, one of the baby doctors was suspicious of her, until someone else
informed them that this was not bruising...

weird stuff, for a first time mom... though, the other sibling, she is not sure of, which one-- we now think it was the third child, then, after me...

oddly, too, THAT sibling said native americans, in an area, where he was, had come up him and asked him, what tribe he was etc... though he was NOT of any, nor are we...


god makes such fun in how he 'overlaps' humans... and , as to how what is
supposedly hidden, or, 'tried to have been washed out' is STILL there, even
if in just bits, through the generations...

and, essential, we are all humans... and came from a 'starting point' so thus,
in some ways, we are all the same anyway...

with a potential to DISPLAY uncountable faucets:
in face shapes...
colors...
sizes...
skin types...

etc...


wow, what an amazing 'flower garden' we are!

Ha, I'm the least worried person I know, blahblah. No tinfoil or bunker here. And no plans to investigate this myself, but it's an interesting question to pursue.

Anonymous data won't flag a person, but could influence actuarial tables going forward for risk factors, regionalisms, etc that at some point could find their way into policy. And fluid boundaries, corporate and state, would concern me about long-term consequences.

Reilly, agreed, but one of the questions I've seen raised (edit: about Brett Kavanaugh...) even by staunch conservatives is whether he might be soft on probable cause.

The records are good enough for me.
They tell you who raised the kids.

A DNA test on yourself won't tell you if all of grandma's kids had the same biological father.
You have to test all the siblings or descendants to determine that.
Or you could just look at the family photos....
A DNA test on yourself might tell if you have some unusual ancestry.
But usually it's mostly the standard random white Euros. :-)

I do know of one of my ancestors who was an illegitimate child, born in 1856.
We know who her mother was, but we don't know who her father was.
She was raised in an adoptive family, and her grandfather named her in his will.

wbw, although your family was Scottish by culture, they could beViking by DNA since many raided and settled there.

That's an interesting thought Jan. Would blow the lid off the family lore that I have always heard.

We never met our daughter’s biodad, but after seeing my daughter when they delivered her, the (white) nurses at the hospital told us they they thought that he was white, in contradiction to the description her biomom gave of him.

As a young child, (mostly white) aquaintances were often surprised to learn she was adopted, and thought they saw a family resemblance between her and me.

Her dna test says she’s 97% East Asian.

How anyone could think that my stunning Asian goddess daughter was genetically related to pasty white European me (beyond us both being humans) is beyond me.

But in our defense, one commonality I’ve noticed about us humans is that the stories other people tell themselves about YOU are often more about them than they are about you. I’ll bet I’m not so different, in that regard.

Best to you people!

hey there say, as to your daughter... you know... it could be, due to her 'copying manerism' from you, as children to, as they grow... makes them look more like us, in
other ways, than just features... :)

you know-- eye sparkles... how much smile they use, or don't use, etc...

that could be why, :)

Now Jan did they inhabit the Shetland Isles

If so, it may be back to the drawing boards for me

Did any Vikings start from

Return of the brown dwarf


Kao heard those results when she was looking at the newest data from the radio astronomy observatory, which helped the researchers determine the strong magnetic field. That field is also helping produce the auroras, which gave off the radio signal they detected. The auroras are similar to those on Earth that happen when our magnetic field interacts with solar wind.

'Ghost particle' found in Antarctica provides astronomy breakthrough
Brown dwarfs can produce strong auroras as well, but the cause behind them is unclear because they don't have solar wind from nearby stars. One theory is that auroras happen when a planet or moon interacts with the brown dwarf's magnetic field.

No deodorant & genetics----I sweat like anyone else; however, my armpits never stink. Climbing partners & others have confirmed this. Genetic testing revealed a variation in the ABC11 gene which is consistent with nonstinky pits (and dry earwax). Shovel teeth were noted by my dentist (he casually mentioned them). Genetic testing also confirmed the obvious; I am (have been) lactose intolerant. The ability to digest lactose after childhood which arose in certain populations was an evolutionary advantage.

Evidence from family, adoption, and twin studies converges on the relevance of genetic factors in the development of addictions including SUDs and gambling.7–13 Weighted mean heritabilities for addictions computed from several studies of large cohorts of twins are shown in Fig. 1.14 Heritability is lowest for hallucinogens (0.39) and highest for cocaine (0.72).

Hehe that won't help you in this era of big data correlation.

You will be correlated.

DMT

I suppose that's true, but then again even if you never get tested, you'll prob be "correlated" by your relatives who do. So I guess you're hosed if you're really worried about it.

Lol, like your "family lore" would go back to the middle age Viking invasions. At least it looks like we know where you get your BS from.

Unsure as to what it actually means, but, I have been recently more interested
In simply the history of recent generations... specifically the things they did earlier in life that were perhaps not talked about a whole lot within the family. Perhapd you could call this more of the “nurture” side of the whole question of how we become who we are.
I recently found my family geneaology mapped out hundreds of years back, but its the much more recent details which seem more interesting or insightful to me.

It's due to how mDNA and Y-DNA are passed down. It's not a fault of the testing, it's a result of biology and inheritance. Both of those are non-recombining DNA with their own known mutation rates. The lack of recombination makes them useful for tracking specific lineages and looking for common ancestors and they're both also useful for dating divergences as the mutation rate for each is relatively well known.

All English, Scottish, Irish and just enough Scandinavian to know someone was raped by a Viking- pure redneck stock.
