Why have humans been able to win in evolution? Was the emergence of human beings inevitable or accidental?

First of all, it must be said that humanity has not yet won, because the evolutionary game continues!

Secondly, don't look at the fact that human beings can now use technology to control energy and control almost all living things, which has a significant impact on the earth's ecology and environment, but there are many biological groups that are more influential than humans in the history of life on earth.

Cyanobacteria

比如藍細菌,這種獨特的微生物大約在27億年前出現,它們在當時極具創新,能夠將水和二氧化碳作為原料,然後利用太陽能製造成可儲存的燃料,這個過程我們現在稱之為photosynthesis

At that time, the Earth's atmosphere was flooded with methane and carbon dioxide, and the Earth was a water-filled planet, so it can be said that cyanobacteria at that time had an inexhaustible resource and flourished casually.

Of course, their unique way of life has also revolutionized the planet's environment and ecology.

Snowball Earth

As cyanobacteria flourished around the world, they flooded the Earth's atmosphere with oxygen and may have frozen the oceans, ushering in the earliest ice ages. All living things either go extinct or change their lifestyles and readapt to the new world created by cyanobacteria.

It is worth mentioning here that some studies have pointed out that a similar situation may have occurred in the ancient Martian period, but Martian life is not as fortunate as Earth, and Martian life may be completely silent due to the complete change of the environment by some species, and lose the opportunity to modify the planet with biology again [1].

The reason for the luck of life on Earth may be that there is significant volcanic activity, and volcanoes are able to provide carbon dioxide when the Earth is too cold for life to thrive, so that the Earth can be warmed again, and life can continue to thrive and transform the planet (since ancient times, the environment has been created by living beings themselves, and planets have only provided a platform).

Does humanity have the ability to completely transform the planet like cyanobacteria?

I think there is, but I don't think humans have the potential to have the potential to influence the blue planet like cyanobacteria.

If we completely remodel this planet, such as using H D, and let the Earth go into H winter and be filled with radiation, humanity will definitely not be able to continue to thrive in such an environment, or continue to thrive in the next environmental recovery.

It's because we're too complex, we depend on too many things, we need crops, we need huge amounts of extra energy to support our activities.

In fact, compared with the real "biotechnology innovation" of cyanobacteria, the existing scientific and technological innovation of human beings is more likeEdiacara Biota.

This group of organisms, which flourished briefly before the Cambrian explosion of species, is unlike anything we know about it now, with almost no special abilities, either like tubes or plates, and even prefer trilateral symmetry or other symmetry rather than bilateral symmetry.

Ediacara Biota

If these creatures live in the Cambrian or post-Cambrian period, and survive the second episode, they should be... I didn't say anything.

In conclusion, the Ediacaran biota is probably the most Buddhist group of organisms on Earth.

And the reason why they can do this is because the creatures before them have left them with their own remains a massive, low-hanging fruit that is deposited on the ocean floor, and they can prosper as long as they can eat it like a tube or a plate.

Trilateral symmetry or no symmetry, compared to bilateral symmetry, is a more wasteful mode of life, only rich enough resources to afford to play.

So it's no surprise that none of the Ediacaran biota survived, and they all went extinct, because they couldn't have outlived the "budget-conscious" latecomers.

Coal layer

If the earth does not have these dividends of oil, human beings will domesticate and domesticate wolves, wild boars and other animals, and it is more difficult to engage in other things than a pile of scrap iron after a tornado into a car

When this wave of dividends is exhausted, it is difficult to say whether the human end will be like the Ediacara biota, maybe not.

Now the question should be,Why is it that humans have the opportunity to eat this wave of dividends, and not other creatures?

There can be many small factors here, such as changes in eating habits, walking upright, brain volume explosions, and so on...... Many small changes eventually created the modern Homo sapiens.

但最關鍵,也是人類之所以是人類的一個原因,我覺得應該是7萬年前左右,不知道出於什麼原因——或許是基因突變吧,現代智人的語言能力開始爆發,能夠詳細描述事物(純屬個人觀點)。

Whether it's a change in eating habits, walking upright, or an exaggerated increase in brain volume, our ancestors lived in a competitive environment with many close relatives of the same ecological niche, and no one replaced the absolute advantage of the other.

But when the language of modern Homo sapiens began to explode, everything changed, when modern Homo sapiens with a gift for language began to migrate, and all the Homo species became extinct, so that only modern Homo species remained of modern Homo species, and it was hard not to wonder if this had anything to do with modern Homo sapiens.

The explosion of language has certainly brought unprecedented advantages, such as the easier inheritance and accumulation of memes, the easier construction of complex social structures, and the easier access to better solutions.

In the history of the hominus species, it is not without that there are more intelligent species than modern Homo sapiens, such as Neanderthals, probably because their diet is more inclined towards high-quality protein, their brain capacity is larger than that of modern Homo sapiens, and they may also have learned to use fire earlier than modern Homo sapiens.

However, when modern Homo sapiens migrated and came into contact with them, they became extinct, and it is estimated that a large part of the reason was the loss of language.

On a similar topic, there is another interesting question:If humans disappear, will chimpanzees repeat the story of the origins of humanity in the Great Rift Valley?

In fact, the question is whether the emergence of a species like human beings is inevitable or accidental.

Personally, I'm inclinedby chanceAnd there are too many conditions required, some of which are simply difficult to obtain, so I think chimpanzees have almost completed the deeds of modern Homo sapiens in the process of long-term evolution.

The history of human evolution is almost the history of climate change on earth, and almost every major change is caused by climate change.For example, upright walking occurred during the outbreak of the Quaternary Ice Age, when the forests were replaced by grasslands.

However, I don't know if the explosion of language has anything to do with climate change, it seems to be more like a non-essential thing for a creature to survive and reproduce, just a quality that happens to appear by accident.

If the explosion of language is only a "non-essential", then how can chimpanzees, which are similar to humans, get this quality, and without this quality, it will naturally be difficult to retrace the path of humans.
