1. A Journey of Thousands of Kilometers: The Secret of Animals That Never Get Lost
There is a baby sea turtle crossing the middle of the Pacific Ocean all alone. This tiny living creature swims tens of thousands of kilometers and returns exactly to the native beach where it was born. The same goes for flocks of migratory birds that fly through the night sky. They do not change their direction even in thick fog or pitch black darkness. There is no map, and there is no navigation device, so how is this kind of miracle possible? It is not simply because they have a good sense of direction. It is not dependent only on the memory of an old leader either.
To solve that secret, scientists tracked the migration routes of animals for several decades. And they finally found a huge clue, which is the massive energy wrapping around the entire planet. It is the magnetic field of the Earth. The Earth is actually like one giant magnet. Invisible magnetic lines connecting the North Pole and the South Pole are always flowing across the entire surface of the Earth. It is an area that humans can never see even if they open their eyes wide. However, surprisingly, specific animals feel this invisible line with their whole bodies.
Humans built compasses or GPS devices by borrowing the power of civilization. On the other hand, animals are born with a high performance biological compass inside them from birth. In academia, this mysterious ability is called magnetoreception.
Then, do animals use the magnetic field simply for the purpose of distinguishing north and south? No, they do not. If that were the case, they would have lost their way in the open ocean. Animals detect the inclination, which is the subtle tilt of the magnetic field. At the same time, they incredibly measure the intensity of the magnetic field that changes by location. For humans, it is just like looking at a smartphone map while checking latitude and longitude in real time. It is the ability to recognize one's position in a three dimensional space.
Why did this ability evolve? It is because losing one's way in the harsh wild means death. It is an evolutionary equation for survival to move to places rich in food and return home for reproduction. Even in the vast ocean and dark night sky, they never wander. It is the most perfect biological navigation designed by nature. In the next section, we will easily uncover the anatomical secret of where this strange compass is hidden inside the bodies of animals.
2. The Compass Hidden in Eyes and Beaks: The Collaboration of Quantum Mechanics and Iron
There is a special photoreceptor protein called cryptochrome in the retina of birds. This protein causes a very bizarre reaction when it receives light. It is a physical phenomenon called quantum entanglement. You do not need to think about it too deeply. You can just view it as an electrical signal reacting to the magnetic field at a very microscopic atomic level.
Birds see the magnetic field directly with their eyes through this signal. It appears in a form where contrast information of blue or red colors overlaps in their vision. To our eyes, it is just a clear sky, but to birds, a huge magnetic field map is unfolding like augmented reality. Is it not truly amazing?
The second passage is hidden around the beak or nose. Inside the cells of animals like salmon or pigeons, there is a microscopic magnetic substance called magnetite. Real magnetic iron atoms exist inside their bodies.
When the magnetic field changes, these tiny magnetite grains physically move. That movement stimulates the surrounding nerve cells. When going north, the cells are pulled, and when going south, they are released.
In the end, animals use a quantum mechanical eye and a magnetic nose at the same time. They look at the direction of the magnetic field directly with their eyes, and they precisely measure the intensity of the magnetic field with their noses. This nanotechnology designed by nature is more precise than any compass made by humans. In the next section, we will look into why this perfect navigation of animals is failing recently due to the shocking interference of human civilization.
3. Human Civilization Disrupting the Magnetic Field: Animals Are Losing Their Way
A bolt from the blue is happening to animals equipped with perfect navigation systems from birth. The biological compass, which had never been wrong even once for thousands of years, is starting to shake violently. Why is that? The cause lies in the modern civilization created by us humans.
We live in a world of a massive invisible wireless network. The electromagnetic waves generated by humanity, including smartphones, Wi-Fi, high voltage power lines, and numerous military radars, surpass imagination. The problem is that these artificial electromagnetic waves completely disrupt the natural flow of the magnetic field of the Earth.
Scientists announced a very shocking experimental result. When migratory birds were left in an ordinary electromagnetic wave exposure area of a city, the birds could not distinguish north and south at all and hovered in one place. This is because electromagnetic waves ruthlessly disrupt the quantum reaction of the cryptochrome protein inside the eyes of birds. The augmented reality map becomes filled with noise and invisible.
The ocean is not safe either. The giant underwater power cables laid at the bottom of the sea emit a massive amount of artificial magnetic fields. Salmon or sea turtles passing through this area lose their sense of direction and get lost. This is the reason why salmon, which must return home to lay eggs, drift into unfamiliar beaches and die en masse quite frequently. This magnetic field disruption is also pointed out as the main cause of the stranding phenomenon where whales wash ashore and lose their lives.
The development of technology gave humans incredible convenience. However, it is like presenting a massive invisible maze to animals, the long time owners of the Earth. How is this invisible pollution threatening the survival of animals? In the final section, we will pinpoint the conclusion of why this homing instinct holds such an important value in the entire ecosystem.
4. The Evolutionary Value of Homing Instinct: Why They Must Return Home
Why do animals go through such a harsh process to return to their hometowns? Even though they have to risk their lives through the electromagnetic wave pollution of humanity. It is not simply because they miss the place where they were born. Homing instinct is a strict equation of evolution on which their survival and species reproduction depend.
Where is the safest, proven place in the natural world? It is the hometown where you were born. The fact that I was born there and grew up safely is the evidence itself. The beach and the river are the most reliable guarantees that the place is safe from predators and abundant in food. Animals use the magnetic field of the Earth as a compass to find the safest breeding ground.
What would happen if animals did not return home and laid eggs anywhere? The ecosystem would collapse instantly like dominoes. If salmon do not return to the river, bears and eagles go hungry. The rich nitrogen components provided by the carcasses of salmon disappear, so trees in the surrounding forests also stop growing. If sea turtles do not return, the organic matter cycle of the beach sand breaks down.
In the end, the biological compass of animals is a core gear that turns the circulation of the entire Earth beyond the survival of an individual. The moment their homing instinct stops, the massive ecosystem chain of the Earth stops together. This is exactly why their footsteps following the invisible magnetic field lines are great.
Now we must throw a question. Is it really okay to keep breaking their compasses for the sake of convenience? It is the time when the contemplation of humanity to protect the great heritage of nature must begin.
