In a new study, the scientists have claimed that all blue-eyed people are descendants of one European who was living between 6,000 to 10,000 years ago.&nbsp;

Originally, humans had only brown eyes in various shades till a specific mutation led to a significant change.&nbsp;

<h2>Why do humans have blue eyes?</h2>

According to the scientists, the mutation is a gene known as HERC2 and it switches off OCA2, which is the gene which helps in determining how much brown pigment we produce.&nbsp;

This is the reason why our eyes turn blue.&nbsp;

The scientists then found out that every blue-eyed person has descended from the same person because all of them have the same mutation.

According to scientists, blue eyes are possessed by only 8 to 10 per cent of the population.

They added that sometimes eyes fail to fully develop in childhood which means that the brown pigment can come later and make blue-eyed children turn into brown eyes adults.

The team, which consists of a group from the University of Copenhagen, was able to discover a genetic mutation which happened 6,000 to 10,000 years ago.

The research was carried out by a team at the University of Copenhagen.

Professor Hans Eiberg from the Department of Cellular and Molecular Medicine, who led the study,&nbsp;said, "Originally, we all had brown eyes. But a genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a ‘switch,’ which literally "turned off" the ability to produce brown eyes."

The P protein is involved in the production of melanin and it contains the OCA2 gene codes which have the pigment which determines the colour of hair, eyes, and skin.

The pigment does not create a blue colour but turns off the mechanism through which brown melanin pigment is produced and effectively "dilutes" brown eyes to blue.

One European, who survived between 6,000 to 10,000 years ago, is ancestor of all blue-eyed people: Study

After being passed from one collector to another for decades, a Bible belonging to a Jewish family in Nazi Germany has finally made its way back to its descendants.&nbsp;

The original owners of the Bible, Eduard and Ernestine Leiter, had to leave their home due to the growing persecution in Nazi Germany. They later died in a concentration camp in Poland. &nbsp;

Over 80 years later, the researchers and historians have traced the couple's lineage and returned the book to the family, a Washington Post report said.&nbsp;

In 2017, the Bible was put up for sale on eBay. Artist and historian Gerhard Roese noticed, the book contained illustrations from a late 19th century famous artist, Gustave Dore. Dore's illustrations implied that the Bible may have belonged to a family during the Holocaust.&nbsp;

The search for the descendants of the original owners was made by the historian along with the support of the researchers at the United States Holocaust Memorial Museum.&nbsp;

Putting in hard labour, the team took around four years to find the descendants. Finally, the owner's great-great-grandson was found living in New York City.&nbsp;

The descendants were overjoyed to have a piece of their family's history returned to them. It allowed the family to learn more about its ancestors.&nbsp;

Bible returned to Jewish family’s descendants after 80 years: Report 

Around&nbsp;14 living&nbsp;descendants of the family of the Renaissance genius Leonardo da Vinci have been identified after&nbsp;decades-long research into&nbsp;his&nbsp;purported remains.&nbsp;

Published in ‘Human Evolution’ journal this month,&nbsp;the findings have resulted from a new genealogical tree going through 21 generations and four branches.&nbsp;

In order to protect their identities, the study&nbsp;provided little information about the living descendants. “The&nbsp;individuals vary in age from 1 to 85,”&nbsp;Project researchers Agnese Sabato and Alessandro&nbsp;Vezzosi&nbsp;told CNN.&nbsp;&nbsp;

The study is a part of the Leonardo Da Vinci DNA Project. The project&nbsp;aims to confirm the remains thought to be his and to 'better understand his extraordinary talents and visual acuity through genetic associations’.&nbsp;

The researchers, who carried out the&nbsp;study, said the results are 'eagerly awaited from an historical viewpoint’. They said,&nbsp;it&nbsp;will help academics to&nbsp;'scientifically explore the roots of his genius, to find information on his physical prowess and on his possibly precocious aging, on his being left-handed and his health and possible hereditary sicknesses, and to explain certain peculiar sensory perceptions, like his extraordinary visual quality and synesthesia’.&nbsp;

Historical documents, which are present&nbsp;in public and private archives and direct accounts by Leonardo's family members descendants led to these findings.&nbsp;
