Who was the first person with blue eyes?
Previous research published in 2008 found that the earliest mutations in the eye-colour genes that led to the evolution of blue eyes probably occurred about 10,000 years ago in individuals living in around the Black Sea.
What is the rarest hair color?
red hairNatural red hair is the rarest hair color in the world, only occurring in 1 to 2% of the global population. Since red hair is a recessive genetic trait, it is necessary for both parents to carry the gene, whether or not they themselves are redheaded.
Is everyone with blue eyes related?
Summary: New research shows that people with blue eyes have a single, common ancestor. Scientists have tracked down a genetic mutation which took place 6,000-10,000 years ago and is the cause of the eye color of all blue-eyed humans alive on the planet today.

When did humans first have blue eyes?
More importantly, there is evidence that blue eyes evolved before light skin — at least 7000 years ago. In 2014, Sturm and colleagues reported on ancient DNA from a 7000-year-old tooth belonging to a hunter gatherer dubbed La Brana 1, unearthed from the north-west of Spain.
Can people with blue eyes see better in the dark?
How Eye Color Affects Vision. … Lighter eyes, such as blue or green eyes, have less pigment in the iris, which leaves the iris more translucent and lets more light into the eye. This means that light-eyed people tend to have slightly better night vision than dark-eyed people.
