There is a very strange phenomenon that the species on our planet are not as good as the next generation. Of course, this is a matter of constitution alone, and most of today's creatures are much smaller than their old ancestors. For example, centipedes and millipedes, it is already remarkable that the centipede can have a length of twenty or thirty centimeters. But the second brother wants to introduce the ancestors of the centipedes today!

Today's centipedes and millipedes are ancestors of ancient centipedes that lived more than 300 million years ago. How mighty are their ancestors? According to the fossils excavated by paleontologists, the length of the ancient centipede is conservatively estimated to be two meters six! And the body of the ancient centipede is very fat and strong, and it is a full-fledged foodie.
Since there were not many giant creatures in the Carboniferous period, the ancient centipede was also a major overlord on the land, and all kinds of living creatures were food in the eyes of the ancient centipede. Many reptiles with bodies similar to today's lions and tigers could not escape the poisonous hands of ancient centipedes. If you take today's python against the ancient centipede, the ancient centipede can eat the python like sugar cane.
Probably because the ancient centipedes were so heavy to kill, it didn't take long for them to be carried away by a wave of god. The span is the Carboniferous period to the early Permian, almost more than 50 million years.
Maybe you think that more than 50 million years is not short, after all, human beings have not lived that long! But for the earth and the entire universe, more than fifty million years is just a momentary concept. I think if humans destroy the environment uncontrolledly, plunder resources, and harm other species on earth, then God will give us at most that much time.
