| The reason for them and how they are traced back to one person. So this 'expert' tells us. Another load of rubbish ?
This Is Why You Have Blue Eyes
Alice Sholl Alice Sholl 18 August 2016
Like our hair colour or height, our eye colour is one of the first things we learn about ourselves when we’re little. And since most people in the world have brown eyes, if you have blue eyes, you probably learned that you were pretty special.
And now, a study has revealed why your eyes are the colour they are. Apparently all people with blue eyes have a single common ancestor. Yep - just one.
The study by the University of Copenhagen found a genetic mutation which happened 6,000 to 10,000 years ago and determined the eye colour of all blued-eyed people today.
Professor Hans Eiberg from the study told Science Daily that originally, everyone had brown eyes, but that a genetic mutation affecting a gene in our chromosomes “turned off” the ability to produce brown eyes.
This gene affects our levels of melanin, which is what determines our eye, hair and skin colour. But for some reason this mutation just ended up altering our eyes rather than the whole package.
If that gene (called OCA2) was totally turned off, for example, it would cause albinism.
The reason scientists think it all goes back to one ancestor is that blue-eyed individuals only vary a little in the amount of melanin in their eyes - while brown-eyed people’s vary a lot more.
“From this we can conclude that all blue-eyed individuals are linked to the same ancestor,” Professor Eiberg said.
“They have all inherited the same switch at exactly the same spot in their DNA.”

| I like how this article presents a theory about a single ancestor for blue eyes, which is interesting. However, Buckshot Roulette genetics is often more complex than a single mutation.

| GB WhatsApp includes improved backup options, allowing users to save their data more flexibly. While the official app primarily relies on Google Drive for backups, GB WhatsApp offers local storage options, making it easier to restore data even without an internet connection visit here. However, it is important to note that using modified versions of WhatsApp, like GB WhatsApp, may pose security risks, as they are not officially supported by WhatsApp Inc. and may not adhere to the same security protocols.

| In Toronto, various cellulite treatments offer innovative ways to reduce the appearance of cellulite and improve skin texture. Radiofrequency (RF) Therapy uses controlled radio waves to heat the skin’s deeper layers, stimulating collagen and elastin production cellulite treatment toronto. This not only helps in reducing the appearance of cellulite but also tightens the skin, providing a firmer and smoother surface. RF therapy often results in visible improvements after a few sessions, and ongoing maintenance treatments can enhance and prolong the results.
