Not critically on-topic, but isn't there some theory about redheads having a remnant of genetic code from giants or some unnatural source thousands of years ago? Would like to hear more if anyone has the info.
Found this with a quick search:
"Egyptians believed that red haired animals and people were associated with the god 'Set', and many of their pharaohs had red hair. A Russian proverb warns, 'There was never a saint with red hair.'
In the Bible the word Adam is supposedly the Hebrew word for 'red' or 'ruddy' and Judas - poster boy tor tratorious - is often portrayed with red hair. Some even believe the 'mark of cain' to actually be red hair."
