Fact #1. If you go back far enough, we're all from the landmass now known as Africa. The best DNA ancestry tests attempt to combat the confusion of race, ethnicity, and countries of origin. They focus on historical migration patterns. The key to knowing where you're from is actually understanding that you're not really from anywhere. Your relatives have been all over, which is why your ancestry test results might be all over the globe, as well.
Fact #2. DNA tests of all kinds have exploded in popularity in recent years. The reasons for getting tested vary widely from one individual to the next. They generally fall into one of two categories: an interest in personal ancestry or an attempt to find a common relative with another individual.
Fact #3. Americans tend to take a particular interest in DNA tests. This is because the vast majority of people in this country came from somewhere else. Even those with native ancestry have more than likely been displaced by colonialism. While those whose families emigrated to this country in recent generations may know a fair bit about where they come from, it's safe to say that many people don't.
Fact #4. There are a few different types of ancestry DNA tests on the market. Generally speaking, they fall into three categories: autosomal, mitochondrial, and Y-chromosome tests. Each type works a bit differently. Some methods are better at detecting traits and origins. Samples are collected using a cheek swab, a spit sample, or a special mouth wash or chewing gum.
Fact #5. Many commercial tests combine some or all of the known methods to give customers a more nuanced understanding of their lineage. Only by analyzing both sides of your family can you determine your true heritage. The more data you test, the more accurate the results will be.
