Not all redheads can trace their history back to an original red haired ancestor. For example, red haired Europeans get their red hair from a variety of DNA differences. It is important to note here that not everyone with the same trait is necessarily so closely related. By studying the DNA in a bit more detail, scientists have concluded that this original blue-eyed ancestor probably lived around 6,000-10,000 years ago. Given that there are lots of ways to get blue eyes, this suggests that the people who share this DNA difference all came from the same original ancestor (or founder). One piece of evidence is that most blue eyed Europeans share the exact same DNA difference that causes their blue eyes. ![]() ![]() Scientists can tell this by looking at their DNA. Surprisingly it does appear that most Europeans with blue eyes are pretty closely related.
