Linger On, Your Pale Blue Eyes

I have blue eyes, with a bit of yellow around the pupil in the summertime, a little more dull gray in the winter. Mike has blue, a little towards the green. Sophia's are crystal blue; Maeve's are like mine without the yellow. Don't know what Leo's will be like yet--he's still newborn dark gray--but they will, of course, be some version of blue. Blue is recessive and that means there's no hidden depths behind Mike's and my blue eyes, as opposed to both our brown eyed mothers who had all these blue eyed kids.

Ann came over earlier this week to chat and distract, and she mentioned something she'd heard or read recently--that all blue eyed people, all over the world, are descended from a single ancestor. Sometime between 6 and 10 thousand years ago, a mutation occurred in the all-brown eyed world population, switching off the ability to make eyes brown. According to an article I read as follow-up, scientists tested mitochondrial DNA in blue eyed folks all over the place, and found that all of us have the same switch in the same spot to turn brown eyes "off", as opposed to brown and green eyed people, who have a wide variation in where their melanin switches are located, DNA-wise.

Little connections everywhere.

Was it you I had talked to about this song? Or Bevin? Last time I was in town I mentioned to someone that when Sophia is older I want to infiltrate her music world by making her a mix CD that would have this song on it. However, when listening to it, it will have to be when she is at that angst age and you haven't already positively influenced her music taste.

We didn't talk about it, but I wrote about it over at Most Nigh last year.

My kids and my husband all have blue eyes while I have brown.
