In the course of Earth's evolution, until primitive fish climbed onto land more than 400 million years ago, it seems that all this began to become related to humans, of course, from the perspective of biological evolution. However, a new discovery some time ago means that the mysterious creatures in the oceans in ancient times may also be inextricably linked to humans.
Strange creatures from 550 million years ago
According to the study, scientists have found that some of the ancient marine life in the Edicaran biota have many genetic similarities with modern animals, including humans.
What is the Ediacaran biota? Simply put, it is a group of ancient biological sites, their appearance time, about 570 million years ago, it can be said that it belongs to the product of the Precambrian period, the discovery of the Ediacaran biota and the Chengjiang biota in Yunnan, China, are 540 million years ago the mystery of the Cambrian life explosion, and some key answers have been found.
In the case of the Ediacaran biota, there are not only more than 30 species of lower invertebrates, but also arthropods, link animals, coelenterates and other phyla, and they are also multicellular invertebrates, which means that the evolution of life on Earth has indeed evolved and multiplied from generation to generation, rather than being "airdropped" on Earth 540 million years ago.
In addition, after the discovery of the Ediacaran biota, with the deepening of research, researchers also realized that many ancient creatures are not visible to the naked eye, many may be only a few hundred microns in size, but they are still active in the earth's oceans, and strangely shaped, are also relatively complex life forms, long before the Cambrian life explosion, it has been lurking in the ocean for tens of millions of years.
The same is true of the new discovery, the researchers found that in the Ediacaran biota, there is a strange creature from 550 million years ago, it has no head, no limbs, not even a skeleton, it looks like a disc the size of a grain of rice, but, genetically speaking, it may be the ancestor of all symmetrical creatures on both sides of the body, including humans.
If it were not for the extraction of their genes, I believe that scientists would not associate them with humans, fortunately, the remains of these ancient creatures also help humans to better understand their origins, and at the same time, they can also tease out the evolution of life on Earth.
Even when studying these ancient beings, researchers have found that until today, the original genetic regulation that controls humans and other animals has been produced at that time, and it has to be said that life is really a miracle.
How did humans come about?
Next, let's look at the evolutionary history of human beings. As we mentioned above, theoretically, more than 400 million years ago, a certain kind of bony fish (ancient lungfish or coelacanth) climbed onto land and evolved into the ancestors of tetrapods, which also led to the emergence of amphibians, which can be said to have laid the foundation for the emergence of humans.
Later, about 300 million years ago, that is, in the middle and late Triassic period, reptiles evolved over a period of time and formed three camps, becoming the ancestors of pterosaurs, dinosaurs, mammals, and, of course, other reptiles that have evolved and continued.
But before the extinction of the dinosaurs, when time had not yet bid farewell to the Cretaceous, this stage for early mammals was a gap in the cracks, resulting in little time for them to evolve towards the perspective of species diversity.
Finally, 65 million years ago, with the meteorite hitting the earth, the dinosaurs finally went extinct, and mammals ushered in the spring of evolution, about 55 million years ago, apes appeared, of course, at this time they still live in Africa, living in trees. Until 12 million years ago, the Great Rift Valley led to dramatic changes in Africa's climate and environment, and new opportunities appeared again.
Some ancient apes came to the ground, and about 5 million years ago, these ancient apes became the direct ancestors of early humans - Australopithecus australopithecus, and evolved for another 3 million years, and some australopithecus's brain capacity exceeded 750 ml.
At this time, more than 3 billion years have passed since the emergence of the first life on Earth, of course, even the strange creatures that are inextricably linked to us 550 million years ago have passed a long time, but this is also the highlight of the history of the evolution of the earth, because this moment begins, which means that the earth has its own intelligent creatures.
After the evolution of the road we all know, early human beings after 2 million years of evolution, and finally in 10,000 years into modern humans, after that, human beings after thousands of years of civilization process, and finally more than 200 years ago into the industrial age, human beings also ushered in a period of rapid development of high-speed, and if traced back, then everything is related to ancient creatures, what do you think?
