do you know? Most living things get the same disease before they go extinct

Everyone knows that all things have a lifespan that restricts it, which is determined from genes. It is like the "shackles" of God, preventing someone from breaking the "rules" of God.

People are born, old, sick, and dead, and the existence of species also has a lifespan. According to the statistics of scientists, if the time from the emergence to extinction of an organism is called its "lifespan". In the billions of years since the birth of life, the average lifespan of each species is about 4 million years.

The "species" with the longest "lifespan" can reach 160 million years, and the shortest "species" have a lifespan of only 1 million years.

A group of bored scientists with nothing to do became interested in biological lifespan. They found out. Before extinction, most organisms will have the same "disease" - specialization.

To be clear here, "specialization" is not a biological disorder that occurs in an individual organism. Rather, it means that the creature only adapts to a unique living environment, and it is difficult to adapt to other living environments.

This kind of "disease" is very common in nature, and it can even be said that it is a tool used by God to eliminate "inferior" creatures. When a population adapts more and more to its current environment and less to other environments, many animals in the population die when the environment suddenly changes.

Thinking about today's human society, the development of science and technology will bring uncertain factors to human society. To adapt to society, you have to learn to use these technologies. For example, the popularity of computer and mobile phones, if you can't use mobile phones and computers, you will be eliminated by many industries.

The same is true of specialized organisms, because they cannot adapt to the new environment, so they will lead to a decrease in number or even extinction.

The most distinctive feature of creatures suffering from "specialized disease" is "choose what to eat and what to live in".

Their symptoms are mainly divided into symbiosis and parasitism, monotonic diet, and narrow temperature and so on.

Polar bears are a typical pathological representative of "parathermia". Because they have lived on the snow-white ice field of the Arctic for a long time, they have evolved thick fur. Although this evolution allows polar bears to adapt to the cold Arctic, it is difficult for polar bears to continue to survive as the temperature gradually warms.

Therefore, in tropical and boreal animals and plants, the damage caused by the symptoms of "narrow temperature" is very serious. Because when the earth's environment warms or cools, there is no room for them to escape.

And the saber-toothed tiger we know well, he is a typical problem of "special diet".

"Food monopoly" means that these animals eat only a few foods, or are parasitic on a few species. This can easily lead to the reduction of the number of creatures he relies on, and he will also be affected by the pond fish.

For example, in the era where the saber-toothed tiger lived, there were many large herbivores with thick skin and thick flesh, such as mammoths and bison that lived with him. Saber-toothed tigers rely on their long fangs to easily undermine their defenses and kill their prey.

But over time, their era came to an end. The number of large herbivores has plummeted, and saber-toothed tigers have gone extinct with them because of the shortage of food.

These two kinds of animals that we know well suffer from the problem of "choose where you live, and what you eat", so they are likely to be eliminated by natural selection.

Besides them, others we know well. And extinct animals or plants are more or less gradually extinct because of the emergence of "specialized" diseases.

Therefore, Kojijun is here to remind everyone: don’t be picky eaters! If you want to live a long life, you must learn to bear hardships and stand hard work.
