I have traced my earliest ancestors to a remote place in the Swiss Alps hundreds of years ago. Supposedly Germanic tribes moved into the area thousands of years ago and displaced the Celtic tribes that were living there. I cannot even think about sunlight without getting a sunburn! People in my family are prone to skin cancer as they get older. I have to wear a long-sleeved shirt and a broad-rimmed hat if I am going to spend any time outside working in the yard, etc. Once I went hiking for a few hours without a hat and I got a bad sunburn on my face and neck.
I have wondered what effects geography and climate have on what we think of as race over a long period of time. People have different complexions, etc. but the genetic differences among the different peoples of the world are actually very small.
The Helvitti were a Germanic tribe that moved into the region North East of Lake Constance in early Roman times and displaced the Celts living there. Julius Caesar had to deal with them at one point when they tried to migrate into the Roman Province of Gaul. Their descendants still live in Helvetia. Are these you people, perhaps?
If I am not mistaken, red hair is a sign of the original Celtic people who once lived in most of Europe. I suppose if the ancient Germanic people originated in central Asia, then they probably did not have blond hair and blue eyes!The Celts were likewise not original to Europe. The remains of what we now consider Europeans can be found in Central Asia, which appears to have provided all the migrants to Europe, India, the Middle East, and to some extent China, for at least 5000 years. As Blam noted, there's plenty of red hair in Libya, but that's because of the blue-eyed, fair-haired nomadic people (generally all the nomads are called Bedouins, but...).
