Red Hair Genes Surging: Humans Still Evolving
16 Apr
Summary
- Human evolution is accelerating faster than previously thought.
- The ginger gene has become more common among Europeans over 10,000 years.
- Other traits like higher intelligence and disease resistance are also increasing.
Contrary to previous assumptions, human evolution is occurring at a significantly faster pace than anticipated. Recent DNA analysis spanning over 10,000 years reveals an increase in the prevalence of the ginger gene among Europeans. This trend suggests that traits like red hair, sported by notable figures, may become more widespread.
Beyond red hair, researchers have identified other traits that have become more common. These include a predisposition to celiac disease, immunity to HIV, resistance to leprosy, a lower risk of rheumatoid arthritis, and a reduced body fat percentage. Intellectual capacity and faster walking pace have also seen genetic selection.
The study, which analyzed ancient DNA from nearly 16,000 individuals in West Eurasia, indicates that most genetic selection accelerated after the advent of farming. This shift to agriculture likely influenced which traits conferred survival advantages. Harvard University researchers are planning to extend this analysis to other regions globally, aiming to uncover more evolutionary patterns.
