This unique mosaic reflects the complexity and diversity of life. Each individual contributes to this bigger picture with their own unique texture. Our genetic structures also tell different stories. The beginning of our DNA map It creates.

As our tracks are shaped by life’s strange oddities, the next chapter actually invites us to discover how these interesting details turn into stories. Because every colored piece in this mosaic, which symbolizes an adventure in itself. Now let’s take a look behind the scenes of these unique stories…

It has been proven that 99.9% of the DNA is the same in all people.

The fact that 99.9% of our DNA is shared highlights humanity’s fundamental genetic similarities. But just a 0.1% difference within this shared heritage creates the uniqueness of each of us. Although this percentage increased to 0.5% with subsequent correction, this is still a very small fraction considering the enormous size of the genome.

The human genome contains approximately 3.2 billion DNA code letters. This difference, which represents 0.5%, corresponds to approximately 16 million letters. If we consider that the genetic code consists of 4 letters The number of possible combinations that these 16 million letters can create is astronomical. This means that each individual’s genetic map has a unique combination.

This enormous diversity makes each of us’s genetic story unique and makes it unlikely that we will have exactly the same genome as everyone else.

The situation is the same for identical twins. Although the situation is completely the same when they are born, the genomes begin to differ as time goes on. The main source of genetic differences is the small changes that occur each time DNA is copied. This process is known as single nucleotide polymorphism (SNP), which occurs with the change of a single letter.

We know that fingerprints are different for everyone. The formation process of these unique scars is also quite complex. Although accepted, the role of genes in determining the shape and size of fingerprints is evolving The fetal fingerprint is not limited to genetic factors alone. So what is effective?

Several factors in the womb can influence the fetus’s fingerprint.

It involves many factors, from the pressure exerted by the uterine wall to the fluidity of the amniotic fluid. Interestingly, although the fingerprints of identical twins are similar, they can have significant differences that can be distinguished from each other. This shows that environmental factors beyond genetic determinism also play an important role in fingerprint formation.

Another factor is our face, the most important thing that distinguishes us from each other. No two of the billions of people on Earth are ‘exactly’ the same. There are major similarities, we admit. but your job to the biological part If you look at it, even one ear is not the same as the other.

Shall we tell you a secret that will surprise you? In fact, no two people in the world even walk the same!

Yes, you heard right. Walking style is also a characteristic that distinguishes people from people.. The simple act of putting one foot in front of the other is actually a complex act shaped by the personal approach of each of us. Over time, the sedentary’s specific walking style depends on physical characteristics such as leg length and hip width, as well as environmental factors such as the developmental habits of the leg muscles.

The world of science also includes people He makes a serious attempt to recognize him by his ears. It is said that it is possible to recognize someone with 99.6% accuracy even from a blurry ear image, thanks to 3D scanning techniques and the unique geometric details of the ears. Now an ear expert can do detective work instead of Sherlock Holmes!

Let’s talk about the eyes, which is another difference. The iris in each eye is unique and dissimilar, as if it has a special cut of a diamond.

Many countries, such as Britain, the US and Canada, have given the green light to use this uniqueness of the iris for identification. However, there is a paradox here: if even twins are not identical, why do the irises of relatives look alike?

The answer to this question lies in the complex world within the iris. Iris; It is a layer where muscles, ligaments, blood vessels and pigment cells mix together. The color and texture of the iris are genetically determined, so the eye color and iris appearance of relatives are similar. The secret, however, is that iris scanning systems not the color and texture of the iris, but the spots and protrusions. It is in his focus.

These details, of genetic codes in the womb Rather, it occurs due to random environmental factors. In fact, the uniqueness of the iris is hidden in the micro details, even if the irises of relatives look similar. We can imagine it as if each of us has a work of art hidden in his iris.

The smell of every person is like a fingerprint.

Our body creates its own olfactory signature. It contains complex and unique components. The secretions in our body harbor various bacteria. These bacteria convert the usually odorless secretions into a unique aroma. Ta da! This creates your scent that makes you unique.

A team from the University of Bristol discovered a combination of 44 different compounds formed by evaporation. “thermal cloud”, suggested it could be used to identify individuals. This essentially means that in the future we could be identified in biometric passports with our own unique body odor, thanks to this scented thermal cloud that surrounds us. Even though it sounds a bit utopian, it still seems like something wonderful.

As we see, this world is like a gallery where every person is a unique masterpiece. Each of us; We convey our uniqueness with fingerprints, iris patterns, body odors and even nail structures. This diversity creates the most beautiful picture of life. Because real art lies in differences.
