Did you ever notice that blue-eyed people tend to be more shy than brown-eyed people? I never did, but now that I think about it, I’m not surprised.
Not just because I have blue eyes and am uneasy in situations where I have to make small talk. I do know a lot of blue-eyed people who in one way or other fit this category too.
A recent paper by two economists at the University of Oslo found that 30% of preschool boys with blue eyes were “socially wary,” compared to only 3% of those with brown, green, or grey eyes.
And when blue-eyed children get a little older, they are more apt to use alcohol and binge drinking as a coping strategy in the face of the anxiety of social situations.
I guess I should be glad that alcohol makes my joints so sore that I am rarely tempted to deal with my anxiety by self-medicating with alcohol. The price is just too high the next day.
Variation in the colour of the eyes from brown to green can all be explained by the amount of melanin in the iris, but blue-eyed individuals only have a small degree of variation in the amount of melanin in their eyes. “From this we can conclude that all blue-eyed individuals are linked to the same ancestor,” says Professor Eiberg. “They have all inherited the same switch at exactly the same spot in their DNA.” Brown-eyed individuals, by contrast, have considerable individual variation in the area of their DNA that controls melanin production.,

Fascinating. I didn’t know that the blue-eyed were that closely related. Thank you for sharing.
I wonder who the first ancestor was… Any idea?
