New research shows that people with blue eyes have a single, common ancestor. A team at the University of Copenhagen have tracked down a genetic mutation which took place 6-10,000 years ago and is the cause of the eye colour of all blue-eyed humans alive on the planet today.

Read more about this, it's fascinating!

Blue eyed people are smarter too, and better looking, and the men are amazingly well endowed.

I guess you can't have pleiadian or Aryan beings without the original beings.

That can't be right. Neither of my parents, nor my grandparents have blue eyes, yet I do. I don't know who taught you that but it certainly doesn't comply with my situation.

Isn't this kind of common sense? 10,000 years ago was when the first humans started showing up, so we're kind of all related to them.

The genetics of blue/brown eyes are thus (you only have to look in a high-school biology book if you don't believe me):
Everyone has 2 genes for eye color. Children receive 1 gene for eye color from each parent.
Brown eyes are a dominant trait. One needs only have 1 brown gene to have brown eyes. So [1 brown+1 blue]=brown eyes AND [2 brown]=brown eyes.
Blue eyes are a recessive trait. One must have 2 blue genes to have blue eyes. Again, children get 1 eye-color gene from each parent.
So.
Two blue-eyed people will ALWAYS have blue-eyed children because both people have all blue genes. It is impossible for their offspring to have any other color eyes.
A brown-eyed person with [2 brown genes] and a blue-eyed person will always have brown-eyed children, because the children will get 1 brown gene from the brown-eyed parent and 1 blue gene from the blue-eyed parent and [1brown+1 blue]=brown eyes.
A brown-eyed person with [1 brown/1blue] gene and a blue-eyed person can have children with eyes of either color. They have a 50/50 chance of having blue-eyed kids because the children will get 1 blue gene from the blue-eyed parent, but may get brown OR blue from the other parent.
2 brown-eyed people who BOTH have [1 brown/1blue] can have blue-eyed children, because the kids can get either 2 brown genes, [1 brown/1 blue], or 2 blue genes. They have a 1:4 chance of having blue-eyed children and a 3:4 chance of having brown.
2 brown-eyed people who both have 2 brown genes can ONLY have brown-eyed kids, because they will receive a brown gene from both parents.
