I find this especially intriguing because I have blue eyes. :)

What about if both your parents have blue eyes, but you don't? My dad has super-pale blue eyes and my mom's eyes are the exact shade of blueberries. My younger brother is somewhere in between the two shades, but I have green eyes. Does that mean I don't share their common ancestor, or what?

Interesting; I've never thought of blue eyes as a gene mutation before... My mom, my brother and I all have blue eyes.

I wonder if people with brown eyes also share a common ancestor.

this is what I kind of get confused on, Y chromosomal Adam...so apparently there were lots of Adam wannabe's running around but their offspring all died and we are all the offspring of y-chrom Adam...but who is his father. And Mitochondrial Eve is, I think, alot older and further back than Adam...it seems like it would be right at the turning of evolution, chimp to human, but it isn't, it's the humans that managed to survive. I guess.

I wish I could read this blog. I always thought blue eyes came about as a result of albinism back in the day in Africa, but that's a genetic mutation that could have happened more than once, so I wonder why they think it's a common ancestor.

edit: Okay I read it, that's really interesting. It really isn't as far back as I thought. I wonder how they know it only happened once. And I raise my glass to the ancestor. Spencer Wells found this guy in one of the "istans" in Asia whose DNA went back 40,000 years. It was funny because the guy thought that Dr. Wells was coming to tell him he had cancer.

I actually have brown eyes, but that was quite interested to hear. I also found it interesting to find out that all humans used to just have brown eyes at one point.
