Do you know anyone with red hair? I think it looks great. It is pretty rare though.
I do! I read where it only occurs in 1-2% of the population!
Is it true that there are more gingers in the northern regions? I thought I heard that somewhere.
Yes - it occurs more frequently (about 2-6%) in people of northern or western European ancestry.
I see. I wonder why that is. Perhaps there was some kind of evolutionary advantage to having bright hair in that area.
Red hair is also associated with fair skin color and lighter eyes.
I noticed that redheads do have pretty fair skin. I didn't know the correlation with eye color, however.
Yes, it's due to the high levels of reddish pigment and low levels of dark pigment.
