Okay, so you know how everyone has DNA in their cells that tells their body how to grow and work properly? Well, some of that DNA is in a special part of our cells called the mitochondria. Mitochondria help our cells make energy, kind of like tiny power plants.
Haplogroup e is a way scientists group together people based on similarities in their mitochondrial DNA. Think of it like a big family tree- you and your cousins might have different last names, but if you look at your family history, you can see how you all have a common ancestor, like a great-grandparent. Haplogroup e is like that- people in this group all have a common ancestor somewhere back in time.
Scientists study haplogroup e to learn more about the history of human beings. They can look at the different variations in the DNA of people in this group and use that information to understand how and when different populations of people moved around and evolved over time. It's like putting together clues in a mystery book to figure out what happened a long time ago. So haplogroup e is a part of our DNA that can teach us a lot about where we came from!
