Where did curly hair originally come from?
The story of human migration and evolution is written in hair DNA. In sub-Saharan Africa, genes favour tight, curly hair. But in east Asia, mutations have led to straighter, thicker hair. In Europe, other mutations brought wavy and straw-coloured hair.
What descent is curly hair from?
The Origin of Curls? So where do curls, kinks, and waves come from then? Most evolutionary theorists agree that human ancestry can be traced back to Sub-Saharan Africa about 500,000 years ago, but it also appears in other hot, sunny places.
Is curly hair a European trait?
In the beginning everybody in Europe had curly hair. The Trichohyalin gene appeared somewhere and spread across the continent. The British Isles were isolated and so they retained their curly hair.
Is curly hair only African?
You may think that highly coiled hair is unique to those of African ancestry, but it is not. It is, however, quite rare in other ethnic groups. So rare, in fact, that when it is seen in Caucasians and Asians it is referred to as a syndrome: “Woolly Hair Syndrome”.
Is curly hair an Italian trait?
Sarah Medland, approximately 17% of Italians have curly hair. Overall, 45% of European people have straight hair, 40% have wavy, and 15% have curly hair. Therefore, Italians are slightly above the European curly hair average. Italian genes have adapted to both the northern and southern climates of Italy.
Is curly hair rare?
Lots of traits are statistically rare: Left-handedness (just 10 percent of the population!), curly hair (11 percent!), and blond hair (4 percent!), to name a few. But of the more than seven billion people on the planet, only 2 percent can claim to have this one special trait.
Is curly hair a Scottish trait?

Is curly hair rarer than straight?
Hair morphology is one of the more conspicuous features of human variation and is particularly diverse among people of European ancestry, for which around 45% of individuals have straight hair, 40% have wavy hair, and 15% have curly hair.
Can Asians have curly hair?
Yes, East Asians can have naturally curly hair.
Is curly hair inherited?
Curly hair is considered a “dominant” gene trait. Straight hair is considered “recessive.” To put that in simple terms, that means that if one parent gives you a curly-haired gene and the other parent gives you a straight-haired gene, you'll be born with curly hair.
Is curly hair dominant in Caucasian?
The gene for curly hair in Caucasians It has been long established that curly hair is a dominant trait in Caucasians and straight hair is recessive.
Do Mexicans have curly hair?
Did you know that over 50% of the residents of Mexico City have curly hair?! Yep, over half of the population has some sort of textured hair due to their Indigenous, Latin American, & Native American backgrounds.
What gene determines curly hair?
There is evidence that trichohyalin (TCHH) may affect hair curl in most/all world populations and that other genes such as EDAR and WNT10A only affect specific populations. Hair curl variation in native Africans is very likely a complex trait with multiple genes influencing curl.
How common is curly hair?
Human hair comes with all sorts of colors, textures and shapes. Notably, African hair is more coiled and dry; Asian hair is straighter and thicker; and Caucasian hair is somewhere in between with around 45% having straight hair, 40% having wavy hair, and 15% having curly hair.
