Apparently the blue eyes thing has been known for a while but I'm only just reading about it today.
https://www.rd.com/article/everyone-blue-eyes-related/“... the fact that all ... blue eyes descend from a single genetic mutation means that every single person on the planet with blue eyes descended from one common ancestor.”
"...a team of geneticists at the University of Copenhagen actually traced that mutation all the way back to a single Danish family."
https://metro.co.uk/2022/10/04/all-blue-eyed-people-on-earth-share-the-same-ancestor-17497235/"Scientists have worked out that, long long ago, all humans had brown eyes. Until a specific gene mutation caused them to change."
"It’s believed the first person to have blue eyes lived in Europe up to 10,00 years ago. And every blue-eyed person alive today has that same mutation present in their body."
"In Britain, the majority of people – 48% – have blue eyes, while 30% of us are green eyed and just 22% have brown ones."
"Whereas there’s a pretty big variation in iris shades between green and brown, blue eyes have a tiny variation in the amount of melanin present."
"And it’s this fact that has led Professor Eiberg, from the University of Copenhagen to suggest that blue-eyed individuals are all linked to the same ancestor."

Only 22% of people in Britain have brown eyes - interesting. My mum and one sister had green eyes, from their Irish mum we thought, and their other two sisters had huge brown eyes. I have blue as do three of my sibs, while one of my sisters has the greenies.
Now that I've looked it up, I see that this idea was floated a good few years ago but for some reason it's coming up again in articles this week.
I sometimes lose track of whether or when conclusions from findings go from hypotheses to relatively universally accepted fact. All the changing (evolving, lol) ideas can get confusing if you don't keep up with new findings and conclusions.
It's fascinating though. I'm impatient to hear "all the answers". (Somewhat like Mormons promise about temple visits - ha!) Yes, I always read the last page of a book first - cannot stand suspense. And I want to know who dies in a movie before I watch it.
I'm not sure how I feel about the idea of being related to every other blue-eyed person in this world. It's half good, half bad maybe. As for the mutation perhaps arising from a Dane, interesting.
It's the time lapse I can't wrap my head around - 10,000 years. I want to know about that first guy.
