Nature has always been full of peculiar colors, and the most peculiar of them is the evolutionary history of biology. There are a large number of creatures on the earth, and these creatures have been able to adapt to the natural environment in the long history, so they have renewed the ability of their own race to survive, even the body structure, like carnivores in order to hunt, so they evolved Sharp minions came out. In the process of adaptation and evolution, organisms have enriched the natural world and made the world more colorful.
And human beings, as the rulers of this world, can also be said to be the most successful creatures in history, because we have evolved developed brains! However, what people did not expect was that an accidentally discovered cave, the evolution of its internal creatures, subverted human's understanding of life! What exactly is this matter about?
2. The accidental discovery of a mysterious cave with a history of 5.5 million years
It is well known that there are various topography and landforms in nature, which are subject to natural changes. In the middle of the world, some mysterious caves are prone to appear, and when people discover these caves, they will often find that they have a very long history and have become an independent ecosystem!
For example, in 1986, a group of scientists, in order to find a suitable open space for the construction of a nuclear power plant, conducted survey operations on the coast a few kilometers away from the black sea of . However, it is very surprising that although they did not find a suitable place to build a nuclear power plant, they unexpectedly discovered a mysterious and very strange cave during the investigation process.
This cave was later named Moville Cave,When it was discovered by scientists, after surveying, scientists were surprised to find that this cave is estimated to have a history of at least 5.5 million years, just because it has been closed for a long time. That's why humans have never been able to discover this mysterious cave.
After conducting an on-site investigation, scientists generally believe that this cave was 5.5 million years ago, when the primitive humans had just moved from the tree to the land to survive, and if you want such a cave, It was the habitat of primitive humans at that time.
For such a discovery, scientists were very pleasantly surprised, so the exploration of this cave was quickly put on the agenda, in order to be able to unlock the secrets of this mysterious cave, So scientists conducted very detailed explorations, and it is precisely because of these explorations that scientists have made unexpected discoveries.
This cave does not look very different from other caves in terms of appearance, but after in-depth exploration, you will find that it is a special cave inside!
2. Deep exploration of the cave, its interior is unexpected
After the scientists have made preparations, they began to explore the cave. After entering the cave, first pass a length approximation It is a 20-meter downward passage, and then it has to move horizontally along a narrow underground limestone passage. After successfully passing through this narrow tunnel, a small lake can be developed in the depths of the cave.
Here, since there is no sunlight for a long time, the inside of the cave is in a dark state.For human beings who live in the sun for a long time, thinking of such a closed and dark environment will inevitably make people feel a little uncomfortable and will bring a lot of psychological pressure to people.
However, this is not the most terrifying. The terrible thing is that after testing, scientists found that the oxygen content in the cave is very low, probably only the oxygen content of the outside world At the same time, the internal carbon dioxide content is more than one hundred times that of the outside.
And, in the process of exploring the cave, the scientists can still smell the small lake, it also exudes a strange smell, it smells like rotten eggs, or burnt rubber After investigating the odor, scientists discovered that the odor emitted was actually the smell of the highly toxic gas hydrogen sulfide!
In such a closed, dark, oxygen-poor, and highly toxic environment, humans cannot stay for a long time. In addition, they are worried that excessive exploration will destroy the ecological environment inside the cave. Scientists also stop at exploring the cave. However, even so, scientists have had enough unexpected gains.
In this cave that has existed for 5.5 million years and has a harsh environment, scientists have discovered the existence of a living system! After careful investigation by scientists, it was discovered that there are 48 kinds of creatures in the cave, including snails and scorpions, and it is worth mentioning that among these 48 kinds of creatures, there are as many as 33 Species are species that humans have not previously discovered! Such astonishing survey results have made scientists fascinated by this mysterious cave.
However,In addition to their surprise, the scientists were also very puzzled. It is well known that living things cannot live without sunlight. So how did these living things survive in such a dark cave without sunlight?
3. Creatures inside the cave subvert human perception of life
Today, human beings have developed and multiplied on the earth for millions of years, and human beings rely on The evolved wisdom civilization became the existence at the top of the food chain. In human cognition, the survival of organisms requires oxygen, sunlight, and stable liquid water.
However, there are no such conditions in the Moville Cave, but there are still living creatures, which undoubtedly subverts the human perception of life.
In this regard, the scientists concluded that the living system in the cave is self-sufficient.
Scientists have discovered that the key to the abundant life in the enclosed world of Moville Cave is the existence of "autotrophic bacteria".
After investigating, scientists discovered that there are a large number of bacteria in the lake water of the Weir Cave and the surrounding rock walls. These bacteria will be converted into sulfuric acid after absorbing sulfide, and after absorbing ammonia It is converted into nitrate, . Only through these two chemical reactions, energy is produced. This process is the process of energy accumulation, which is similar to that of ordinary plants to absorb carbon dioxide through photosynthesis.The ecology inside the Moville Cave is to make up for the lack of sunlight.
In addition to a large number of bacteria, other organisms grow in the caves. They also have some signs of evolution. Scientists believe that it is precisely because of their long-term survival in a dark environment that they must undergo evolution To adapt to this harsh environment, all its eyes are degraded, and this will play a very important role in biological research.
At present, due to the harsh environment inside the cave, there are now less than a hundred scientists have explored the Moville Cave. However, even if the exploration of caves is not comprehensive, it also gives humans a new understanding of life. This is also a good thing for us. Perhaps there are still places in some unexpected places. More surprising phenomena are waiting for human discovery!
Summary
When people discovered the Morville Cave, they believed they were shocked by its wonder. There is such a world on Earth that resembles an alien. I am full of curiosity about how many unknown things there are on this planet.
In the Moville Cave, scientists discovered the unique ecological environment in it, and believe that through the study of this cave, humans can gain a lot.
and so far, in the true sense, the number of people who have explored and researched the Moville Caves is less than 100.The understanding of this wonderful place is not deep, but it has subverted human cognition. I believe that with the further deepening of exploration, more amazing research results can be obtained in the future, let us wait and see!
