  • I took a DNA ancestry test. It didn’t tell me where my ancestors came from…

    At-home DNA ancestry tests have become hugely popular in recent years. More than 26 million have taken one of these tests. If their marketing is to be believed, they can help you learn where your DNA comes from, and even where your ancestors lived.

    But the information that can be inferred from your DNA is actually much more limited than testing companies are letting on. And that has lead consumers to misinterpret their results — which is having negative consequences.

                          @legobarbarian A murder that was like 80 something was traced through one of his family members dna that used the ancestry service. I assumed it went to a government data base.

                                            This shows why we need national health care in the US. The more samples these companies generate and share, the more the health care INDUSTRY will discriminate. They won't be open about why they decline coverage, they'll invent some plausible excuse to discriminate, and even though you have some sickly, at-risk relatives you may never be sick a day in your life. Great for you, but say you're in an auto accident at fault by another driver and you have no coverage? Well, welcome yourself to the growing number of Americans being bankrupted by a greed based medical system. Expect all your insurance coverages to skyrocket as your credit ratings plummet (how my risk as a driver is suddenly compromised by my inability to pay medical bills is a head scratcher), you will never be able to buy another big ticket item again, even though car ownership is pretty much a given in most of the US in order to work and have a normal life. Goodbye to any thoughts of putting kids through college or hoping to leave any kind of inheritance and the injustice now becomes "generational". Single payor (good riddance to health insurance companies, hmo's, credit collection agencies, high six-figure salaried administrators and slews of middle men responsible for making US health care the most expensive in the world) health care is the only option (unless hospitals return to being charity based, non-profit entities they way used to be) to keep millions of Americans from becoming a hopeless underclass. To all those right wingnuts screaming foul to socialism and returning to the "good old days" (when that was someone might have to explain to me what made that elusive period so good), I can tell you this one truth, we are stronger as a nation and people when we had a healthy prosperous middle class with a few millionaires than we are today with a burgeoning hopeless army of the working poor and obscenely wealthy billionaires. This idea propogated by the one-percenters, that only the rich can provide the capital to create new jobs is ridiculous to the insane. America became great because enough people had enough time and spare money to tinker with an idea in their garage and pursue the American dream. People who will never, NEVER, see their situations improve have been duped into being the gnashing, snarling rotweillers that protects a policy that is systematically disassembling America's middle class. These are the very same people that still tenuously have the power to improve their lives and that power comes in the form of the vote.

                                                          a geneticist would have said the same thing. it's common knowledge that "races" by all means aren't real by genetic standards. it's a sociologists job to study and explain how social categories like these impact us

                                                          First, on "Shemites" and Semites- your DNA analysis might say you have jewish ancestry, which would most likely be descendants of Shem, before his descendant Eber, the first semite was born.  Your report might say you have west Africa ancestry, which may not clearly specify that it is Caucasian- Hamites, specifically... the Amber (Caucasian) Race originated farther south than the very white Caucasians; the Bible is a history of the Amber Adam/Eve lineage; the very white Adam/Eve were actually named Ask and Embla, from an Eden much further North.  There were five Edens.  My advice is don't get scientific DNA analysis- all the medical association wants to do (generally) is sterilize you; make you frigid, impotent, infertile... so that they can have Increase in their special elite ranks, while suppressing increase in yours!

For you folks who like late-nite shows, check out Steve Colbert and John Oliver under this subject. AP, you are doing a lot of commenting for someone who claims they know what they are talking about. If you know so much, you don't have to try to beat it in, just allow the people to learn on their own.

You view terms of service. Apparently not only have fear mongering folks like yourself never done an ancestry test, but you also apparently don't know anyone who has. In other words, more proof that you all don't know what you are talking about.
