"But then, during the Cambrian period, about 600 million years ago, a variety of invertebrates—arthropods, mollusks, brachiopods, annelids, and other creatures that were essentially identical to modern animals—suddenly appeared en masse over the course of a few million years. This phenomenon is known in paleontology as the Cambrian Explosion!"

"It's as if these organisms suddenly appeared on Earth. Or perhaps the single-celled organisms that had been swimming for billions of years suddenly accelerated their evolution, as if they had received some kind of revelation."

Chang Wei knew that Professor Ouyang Boyuan was trying to use the Cambrian Explosion to sway his students' thinking towards the existence of a Creator. But he was clearly wrong this time! Chang Wei knew that this was the masterpiece of the three alien civilizations.

Because of war, they fell into self-destruction. The last survivors were forced to unite again, paying a huge price to transform the Earth and create life to continue the future. After the birth of humanity, they finally descended as "gods" and ruled for tens of thousands of years before hiding within human society until today. This is also the main reason why observers of the Seeker civilization continue to remain in the solar system, observing and recording the development of human civilization.

The audience in the livestream and Tang Qi were also captivated by this wonderful topic, listening with rapt attention. Unconsciously, they were transported into that ancient era of exploding life and unparalleled splendor.

Turning his head slightly, Tang Qi was surprised to find that Chang Wei did not seem to agree with the views expressed by the professor on the stage, and began to shake his head unconsciously.

"Chang Wei, do you think he said something wrong?" Tang Qi asked while adjusting the angle of the camera and secretly pointing it at Chang Wei.

Chang Wei ignored Tang Qi's actions and explained in a low voice: "If you have knowledge of geological structure, you will know that the rock layers of the earth's crust are accumulated layer by layer, and each layer represents a geological period. However, there is a strange phenomenon in the earth's rock layers. That is, in a certain rock layer, the upper rock is horizontal, while the lower rock is vertical."

"If the strata were deposited slowly, bit by bit, then this phenomenon doesn't conform to the natural rules of geology. After dating, we found that the upper rocks were formed in the Cambrian period 550 million years ago, while the lower rocks were formed in the Proterozoic period 1.7 billion years ago. In other words, there is actually a 1.2 billion-year-old transition layer between the two layers."

"Then why did this 1.2 billion-year-old transition layer disappear? Because it's not a rock layer, but an ice layer! And this is a global phenomenon! What do you think?"

"Haha, actually, the Cambrian explosion of life is related to its disappearance. When the Earth entered the Cambrian period, the 1.2 billion-year-old ice sheet began to melt, and the vast amount of minerals, organic matter, and other rich elements trapped within it flowed into the sea. These substances directly changed the chemical composition of the ocean at the time, bringing unprecedented environmental changes to the single-celled organisms living there."

"Eventually, some organisms adapted to this environment over the course of their long evolutionary journey. They eliminated these excess elements from their bodies in the form of calcium phosphate and calcium carbonate minerals. Other organisms, on the other hand, utilized these minerals to form bones, teeth, and shells, and developed new forms of life in the form of multicellular organisms. This ended the long-standing dominance of single-celled organisms, allowing Earth's biological forms to become diverse and flourish."

"This is the truth behind the Cambrian explosion (and also the method used by the aliens)." Chang Wei didn't say the second half of the sentence, but he quickly turned his head and discovered that the camera was pointed at him and Tang Qi's stunned and surprised face.

"Chang Wei, how do you know this?"

Chang Wei quickly glanced away and replied perfunctorily, "I guessed."

When the live broadcast room came to its senses, it exploded instantly!

"Holy crap! I was wrong! This guy is definitely a big shot hiding in the city!"

"Great! If no one has published this theory yet, I'll publish it! Maybe it will immediately become a world sensation!"

"The guy upstairs, stop dreaming! I've already started writing my paper, so just wait for the lawsuit!"

"This Chang Wei is definitely not simple! He might be an alien in disguise! I suggest the anchor call the police immediately and have him sliced ​​up!"
