You're Seeing More Redheads Than Ever And Evolution Is Why
Just a few years ago, there were concerns that minorities like blondes and redheads were going extinct. The future belonged to Miss Clairol because they're recessive genes and with just five generations of bad biological rolls, you could have less chance of Scottish hair than Senator Elizabeth Warren has of being Native American.
It may be that scientists just weren't seeing the signals.
Instead of going extinct, a study of 10,016 newer ancient West Eurasian genomes, plus 5,820 existing ancient sequences and 6,438 modern ones finds that red hair and fair skin have become more common over the last 10,000 years, not less. Evolution not only didn't slow down in that time, natural selection could those traits to speed up over the last 4,000 years.
