 Hair is simply amazing. The human body and the mechanisms by which it
adapts to its environment are mind boggling, and our hair color,
texture, porosity and everything else plays a massive part in how well
we succeed in a particular environment (or at least it did before we
started living in these air conditioned covered boxes).

We all love and nourish our hair, but it’s so easy to forget just how
magical these dead cells growing from out of our scalp really are.

Enter the Melanesians, a native group of people living on the Soloman Islands northeast of Australia famous for their beautiful dark skin and naturally blonde hair.
Yep, that’s right. They don’t sport weaves, wigs, extensions, permanent
dye, temporary dye, some weird henna reaction, or whatever else anyone
uses to get the blonde look that’s so typical of the caucasian
persuasion. Ten percent of these islanders actually come by it
naturally.

The odd combination has got scientists wondering about how such a color combo develops over time. According to the Global Financial Newswires,
many scientists have long thought that their blonde hair was a result
of a diet high in fish, perhaps bleaching by the sun and salt water, or a
reminder of the island’s historic relations with people of European
descent.

In fact, the blonde Melanesians have blonde that is unique solely to
them. According to the study in which scientists compared 43 blonde hair
islanders to 42 dark hair islanders, blonde Melanesians have a variant
of a native gene called TYRP1 that plays an important role in the
melanin biosynthetic pathway. This variant is completely separate from
what causes blonde hair in Europeans, and doesn’t even exist in the
European genetic set.

What’s truly beautiful in this fascinating discovery, as so perfectly
stated by the study author Sean Myles, a geneticist at Nova Scotia
Agricultural College, is that “it’s a great example of convergent
evolution, where the same outcome is brought about by completely
different means.”

And that makes hair of all textures, types and colors absolutely unique and absolutely beautiful.
