There's something about a blue-eyed girl that just hits different. That stops you in your tracks. Have you ever wondered how those blue eyes came into existence? No? Just me I guess. Well, I looked it up and I am going to tell you anyways.

The earliest humans were from Africa over 200,000 years ago. For all of human history going back to when we split off from a common ancestor with chimps we had dark eyes. Ever see a blue-eyed chimp? No, you don't.

The oldest skeleton with DNA containing blue eyes was found in Spain and that dates back to about 7000 years ago.

They say that that guy actually had dark skin like the people of sub-Saharan African which is kind of crazy. Wouldn't have expected that

Scientists also say that the all people with blue eyes can trace their genes ALLLLLLLLLLL the way back to one single ancestor. They theorize that this person was likely from an area near the Black Sea

The scientists think that the genetic mutation to turn dark eyes to blue happened around 10,000 years ago.

That recessive gene quickly spread across Europe.

People in Europe went from having ZERO people with blue eyes to possibly as much as 40% of the population in just 10,000 years. That's pretty remarkable considering how slow evolution usually occurs in nature. Why that happened is kind of a mystery

Scientists think it was either due to the fact that having light eyes in Europe was beneficial due to the lower levels of sunlight happening there as opposed to Africa and the Middle East and other parts of the world around the tropics

Or…they think it's because blue eyes were seen as more sexually attractive
