How did the Mayan civilization die out?

Maya civilization is one of the three great civilizations in ancient America. Why it suddenly disappeared has always been a difficult problem in academic circles. In the past, many scholars put forward climate theory, war theory, trade theory and so on, but these theories have no sufficient evidence. Recently, some American scientists conducted a medical examination of Mayan mummies and came to another conclusion: the Mayan empire disappeared-sexually transmitted diseases led to the demise of Mayan civilization. Maya civilization is the only civilization that was born in the tropical jungle instead of the big river valley. Its sudden decline has been a mystery. "Maya civilization is an Indian civilization created by the ancient Mayans, an outstanding representative of the ancient Indian civilization in Central America, one of the three major civilizations in ancient America, one of the world-famous ancient civilizations, and the only civilization born in the tropical jungle instead of the big river valley." Dong Jingsheng, a professor of history in Peking University, said. "However, around the 10 century, the Mayans suddenly moved southward in large numbers, and finally, the Mayan civilization that flourished for a while suddenly declined." Professor Dong said. The cause of economic recession has always been a difficult problem for scholars. Volcanic eruption? Earthquake? Hurricane? Plague? Or peasant uprising? Frequent civil wars? Foreign invasion? Business route transfer? ..... put forward various speculations, but the evidence is insufficient. In May 2007, archaeologists excavated an ancient tomb of the Mayan Empire in Honduras, where mummies were found. Recently, the medical examination of Mayan mummies by American scientists shows that the reasons for the inexplicable decline of many Mayan cities are probably related to the spread of diseases, especially sexually transmitted diseases. Is it the chaotic marriage system or the unique living customs that make sexually transmitted diseases spread rapidly among Mayans? According to the research findings of American scientists, the reporter interviewed Zhen Orange, an expert in peking university health science center Medical Room. She said, "If American scientists find sexually transmitted diseases from Mayan mummies, it can be inferred that this person died of sexually transmitted diseases." "Compared with other infectious diseases, the spread of sexually transmitted diseases is not particularly fast. It is transmitted through blood and body fluids. " Dr. Zhen Orange said. Dr. Zhen Orange also said, "Before penicillin was discovered by human beings, sexually transmitted diseases threatened human beings as much as AIDS threatened modern people and could not be cured at all." /kloc-Europe in the 0/5th century was in the Renaissance, and sexually transmitted diseases posed a serious threat to Europe at that time because of advocating the idea of human liberation and bathing for men and women. However, when humans invented penicillin, sexually transmitted diseases were controlled. However, during the decline of Mayan civilization in the 10 century, there was no good treatment for sexually transmitted diseases. "If we speculate that Mayan civilization may be destroyed by sexually transmitted diseases, I think the living habits of Maya people must be different." Dr. Zhen Orange said. "In other words, the Mayan marriage system was very chaotic, which made the sexually transmitted diseases brought by outsiders spread rapidly through sexual life; Or, they have special living customs that can be spread through blood. " Dr. Zhen Orange explained. Maya often drilled holes in the ears, tongue, fingers and genitals to get blood. These living customs may lead to the spread of sexually transmitted diseases. Professor Dong Jingsheng denied the previous speculation about Dr. Zhen Orange. "The Mayan social organization is based on the family, and the family is the core of Mayan society. The husband power system is implemented, but the mother or older woman still has a certain position in the family. Not during the matriarchal clan period. " However, Dr. Zhen Orange's latter guess has been confirmed by archaeologists. Although the Mayans created splendid culture, some of their customs and habits were incomprehensible to generations. They have the habit of taking drugs, even through the anus. In addition, archaeologists found that Mayan elites often drilled holes in their ears, tongues, fingers and genitals to extract blood for sacrifice to the gods. Dr. Zheng believes that this custom of Maya people may make sexually transmitted diseases spread through blood. "Besides, sexually transmitted diseases can be transmitted to children through Maya mothers," added Dr. Zhen Cheng. Archaeologists also found that the Mayans did not eat meat, and protein was obviously lacking in the bones of the Mayans in the later period. "In this way, it is possible to reduce the Maya's own immunity to the virus." Dr. Zhen Cheng said, "In the absence of therapeutic drugs, the patient's own immunity is particularly important." According to Dr. Zhen Cheng, there have been many outbreaks of infectious diseases in human history, both locally and globally, which almost changed the course of human history several times. Smallpox, syphilis, cholera, influenza, Japanese encephalitis and even AIDS are not too strange to us. They have ravaged or are ravaging mankind. According to Dr. Zhen Orange, scientists can find the scars left by smallpox from the mummy of Pharaoh Ramisis V and other ancient Egyptian mummies. It is an infectious disease caused by smallpox virus. Other speculations about the reasons for the disappearance of Mayan civilization: 1, epidemic disease theory: Some scholars believe that climate change has led to serious drought and epidemic disease, resulting in the decline of Mayan society. 2. Debate on War: Some scholars believe that the collapse of the Mayan kingdom was caused by wars between tribes within Maya and foreign invasions. 3. Trade theory: There are still many scholars who believe that with the development of maritime traffic, inland river trade has been replaced by maritime trade, so the Mayan cities that are connected with rivers in the depths of the jungle and rely on inland river trade for a living have lost their existence and caused the collapse of Mayan society. 4. Aliens said: Scholars even boldly imagined that the Mayans came from another planet with a highly developed civilization in the universe. The collapse of Mayan civilization was due to the explosion and destruction of Planet X in the solar system as their transit station. The earliest discovery of Mayan civilization can be traced back to Columbus in 1502. After Columbus first discovered the "New World" 10 years, he sailed to America for the last time. The ship landed in the Gulf of Honduras, and Columbus and his crew excitedly set foot on the long-lost land. In the local market, a beautifully made pottery basin caught his attention. The seller told him that this exquisite pottery basin came from "Maya". This magical name was first introduced to the ears of Europeans. However, it was not until the end of 18 that Maya civilization attracted people's attention. Due to the development of the Enlightenment and the improvement of historical vision, western talents became interested in American civilization that they had ignored for 200 years. Archaeologists want to find a lost civilization. Palenque, Copan, Tikal ... The world-famous ancient cities representing Mayan civilization were awakened; The 20-story pyramid, the stone altar decorated with exquisite relief, the observatory for observing the movement of celestial bodies ... an incredible magnificent building has held the breath of the whole world. Mayan archaeology has made great achievements in the past two centuries. Although there are still countless mysteries, a lost Mayan world has finally been recovered bit by bit.
