I am adopted, but several genetic characteristics, common to being Northern European, such as red moles (I'll call them beauty marks) and keloid scarring, common to Spanish/African or darker pigmented ethnicities have sprung up in the last ten years. My adopted parents said that they were told that my birth parents were most definitely of Irish ancestry. I consider myself of Irish acestry if anyone asks what my ancestry entails. My skin color, according to a colorist I see, is between olive and a warm yellow.
I also had red hair until I was about 6 years old and then it turned brunette. I still have a lot of red in my hair, but would be considered brunette all the same. My daughter, who is 1 year old has red hair, so she must have gotten it from me, since my husband was platinum blonde as a child, although he too has red in his hair now that he too is a brunette.
Hmmm, I think it would a very interesting study, to see if people of Celtic ancestry tend to have a higher population of AS, but in the end does it really matter?
We're stuck with it or thrive in it and live our lives. The only reason to find out if the above is true would either be so NTs could cure autism or use Celtic ancestry as a means to irradicate a "bothersome" percentage of the population.
