As you look closely in the mirror trying to disprove this, physics explains how this is possible. Your eyes appear blue in the same way that the sky appears blue- scattered light. The iris, which is responsible for eye color, has three layers. Each layer has different color pigments such as yellow or brown which, when combined, make hazel and brown eyes.
But blue and grey eyes have a brown pigment in one small layer of the eye and as light bounces off of the iris, creates a blue color due to its short wavelengths!
As recently as 1985, babies were operated on without anesthesia because doctors believed they feel no pain!
The author of this paper shows how babies and infants have been treated as lesser beings in the past because of the fact that they haven't developed their full cognitive capacities. People have judged babies' cries as 'random sounds' and their smiles as 'muscle spasms.'
This seemed to be confirmed through science because babies would be pinched and prodded with needles when they were newborn. Doctors observed that babies reacted more violently as time went on. They thought this meant that the ability to feel pain would develop over time. However, the reason for this was actually because of the anesthesia that the mother had received, and that had been passed on to the baby.
It wasn't until 1985 where studies on babies showed that not only did they feel pain, some babies were dying because they were being operated on without any anesthesia or anything to prevent the pain!

Some awesome lists!
Having blue eyes is a genetic mutation that results in the body's inability to produce melanin to make eyes brown, which is the natural color. Between 6000 to 10000 years ago, a genetic mutation occurred that made a single human person lose the ability to make brown eyes.
Their research showed them that people with blue eyes from all around the world have the same gene changes that are linked to the one mutation that makes their eyes blue. Brown eyed people have different genes in that same DNA strand, so they believe that this indicates blue eyed people all come from the same ancestor!
Researchers have shown that pigeons have remarkable perception. They went to a park and had one researcher ignore the pigeons, while the other was hostile and chased them away. Then later, they each returned, and neither tried to chase them away.
The results were staggering: the pigeons ran away from the person who chased them away earlier, but not from the other one. They even recognized the people correctly when they switched their clothes. They were able to recognize their faces!
