What's Haplogroup A (mtDNA)?
Haplogroup A (mtDNA) is something you have inside your body that can tell you where your family originated from a long, long time ago. This special thing is called mitochondrial DNA, or mtDNA for short.
Now, imagine that we all have a family tree with many branches. Just like that, our haplogroups also have their own branches. Haplogroup A is just one of those branches, and it tells us that our ancestors came from Africa around 180,000 years ago.
Think of it like a long, long journey your family took a long, long time ago. Haplogroup A is like the stamp on your passport that tells you where you came from at the start of your journey.
Scientists have studied haplogroup A and found out that it can be even broken down into smaller groups to tell you more specific things about your family history. For example, if you belong to Haplogroup A2, it is likely that your ancestors eventually moved out of Africa to populate other parts of the world.
So, in short, Haplogroup A (mtDNA) is a part of your DNA that can help track where your family came from a really long time ago.
