Blue-eyed humans have a single, common ancestor

All of us still have one brown eye. Sometimes I can make mine blink.

Aren’t those two-eye-colored folks chimeras?

Bright light?

I’d like to see the actor on the right (name escapes me, though I know he’s the “new” James Bond) take over the Martin Cruz Smith character of ‘Arkday Renko’ played by William Hurt in ‘Gorky Park.’

They need to make ‘Wolves Eat Dogs’ (the new Renko story) into a movie. He would be awesome in the lead. :)

(I know this has nothing to do with anything, LOL!)

[bannie]

Sometimes they do call me "special"...

[fortunecookie]

You are correct. Actually I got my paternal grandmother’s eyes.

Not her actual eyes??! ;-)

Both my parents have/had blue eyes. My mother's stunningly so. Mine are green, the same green as the green flecks in my maternal grandfather's brown eyes.

How did Liz get violet eyes?

[toddlintown]

“Bright light?”

Nah, fear.

I went to college with a guy like that - one blue eye, one brown.

Yeah, but how do you feel?

Nice pic of the Husky. I used to work with a lady who had one brown eye and one blue eye. I once asked her how she filled out her driver’s license information about her eye color. She said she always wrote “Blue” since that was her dominate eye...made sense i guess.

My eyes are similar. They still look mostly brown, but have pools of green throughout the reddish brown. However, as a child, my eyes used to be a very dark brown.

This is also true of my dad and two of my brothers. They started with dark brown eyes when younger. My dad and one brother are almost completely green now and my other brother’s hazel. I’m the youngest, so I figure it will be another 15-20 years until my eyes are green. Weird.

Am I evolving?

My husband’s parents both had blue eyes and nothing but blue eyes in both families. They produced my husband and his sister with brown eyes-his younger brother has blue.(no it wasn't the milk man.) Both my husband and his sister had 3 children each, two blue eyed children each and one brown eyed child each. It's not what I've read should happen with genetics.

That’s the funniest thing I have ever read.

Damn Canadians.

[Ethrane]

So I have blue eyes and my wife has brown eyes. Her mother had blue eyes, her father brown.

I tell her that our future children are going to have brown eyes. That's not quite right, is it?

Nope....odds are 50-50 for blue eyes vs some brown/green combo

[syriacus]

I have green eyes. My husband has brown eyes. Two of our daughters have blue eyes.

Does that mean our daughters don't share our ancestry?

[Ethrane]

Not at all...

Your husband is a heterozygote with both a blue and brown eye gene....brown eye color is the dominant gene expression. At some point in his family tree he had a blue/green eyed relative.

People with green eyes have a blue eye gene too...the eye color gene is subject to variable penetrance which can lead to different ‘shades’ of color from dark brown to green etc.

Your two daughters eye color has nothing to do with their ‘ancestry’...
each of your children

We all have a single, common ancestor. We have Adam and Eve and we all also have Noah. I wonder about them calling my blue eyes a mutation. Were they not just a distinct variation and recessive in the original brown eyed pair? Why do they think that they were a mutation? What do they actually know and are going on to believe that blue eyes are a mutation? They do not seem to think that all the different intensities and hues of brown and green are mutations or at least they do not label them as such. Is not the melanin turned on and off to all different degrees in these folks?

What was Adam and Eve's daughter's name?
