    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.

      India, Pakistan and Bangladesh are some of the most ethnically diverse countries in the world. If I were them I would not be satisfied putting that ENTIRE population under a broad “South Asian” term. It’s 1/8 of the world’s population. It deserves more thorough regional study

                  Its not a guess its more like a hypothesis because its actually backed up with evidence that leads the company to believe into the conclusion they chose.

Sequencing a whole genome, for instance, might be easier to do in the coming years and, perhaps couple with richer database, may offer us a chance at a greater, more bespoke understanding of our own ancestry. Great video, thank you.
