Genetic Defects

For John, BLUF:  Sorry about that.  Nothing to see here; just move along.

All blue-eyed people have a single ancestor in common

This is from Business Insider, Zach Williams and Jessica Orwig reporting, 21 September 2017.

If I understand this correctly, we are all blue eyed, but normally people have an additional factor in their genes which gives them another eye color.  Blue eyes themselves are a genetic defect.  That is interesting.

The other interesting thing is that I had understood the blue eye problem to come from the south shore of the Black Sea.  The graphic has it coming out of Africa.

Hat tip to the InstaPundit.
