For Homo erectus, I believe many friends want to know what they look like, but due to the age, we can only make some guesses about the appearance of Homo erectus. However, the powerful recovery technology of modern science and technology makes the impossible possible. As we all know, human appearance depends largely on the structure of bones. If we can find the skull of Homo erectus millions of years ago, it is possible to restore the appearance of Homo erectus through modern reduction technology.
So how many years ago did Homo erectus, the ancestor of mankind, appear? According to modern archaeological exploration, the Stone Age was discovered in the Loess Plateau of China, which was the age when Homo erectus lived, about 265,438+ten thousand years ago. Homo erectus was also found in the Caucasus of Georgia (6.5438+0.8 million years ago), and in Indonesia and Africa, indicating that Homo erectus had spread all over the world at that time.
Through archaeological discoveries of upright human head bones, scientists have successfully restored the appearance of "human ancestors" through modern restoration techniques. At this time, we found that the appearance of Homo erectus, the ancestor of human beings, was somewhat different from that of modern people. Of course, the gap is not as big as we thought. According to the conclusion of archaeologists, Homo erectus was first discovered in Indonesia and China, which were the fossils of the famous Javanese and Beijingers respectively.
Homo erectus is the first ancestor of mankind similar to modern Homo sapiens. Their height is higher than that of modern people, and their brains are bigger than those of Australopithecus, which is still a little different from modern people. Moreover, their faces are somewhat different from ours. They look flat, such as prominent brow bones. Homo erectus had longer legs, which helped them to hunt and live better in the vast forest.
Homo erectus is obviously bigger than modern people, which helps them to control the temperature and water balance better and is very suitable for living in the open forest. Although we have restored the appearance of our ancestor Homo erectus with modern technology, there are still many secrets to be solved for Homo erectus. For example, when Homo erectus ate food, we should know that meat occupies a very important position in human diet.
Some scientists think that Homo erectus was mainly carnivorous, while others think that they had a wider range of eating habits. They have obvious wisdom. They first learned to use fire, which is an important symbol of an intelligent life and the most important difference between animals and intelligent life. Being able to use fire can not only effectively resist the attack of wild animals, but also eat cooked food. Greatly improved the viability, and may change to the direction of the earth overlord.
The use of cooked food can also make Homo erectus have more nutrition, promote brain development and become smarter. It was generally believed that Homo erectus could not swim. This theory is still generally accepted until now, but a discovery in the Philippines (possibly in Sulawesi) overturned this discovery and opened an exciting possibility that Homo erectus might be a more capable sailor than we thought before.
There is no doubt that there are still many mysteries about Homo erectus. We have to wait for scientists to piece together the map step by step before we can complete the pedigree of human evolution, but the evidence at present is not sufficient. I believe that scientists will soon have a deeper understanding of the ancestors of Homo erectus.
Some scientists believe that Homo erectus is not the true ancestor of modern people, but the ancestor of modern people may be modern Homo sapiens, which appeared in Africa tens of thousands of years ago. Some scientists believe that early Homo erectus later became extinct and did not continue to evolve until modern Homo sapiens appeared. However, some specimens from Java, Indonesia show that they lived at least 40,000 years ago. If this conclusion is correct, it means that they exist with Homo sapiens, although it may be only a small part in Indonesia.
The emergence of modern Homo sapiens may also have evolved from Homo erectus, so the ancestors of human beings were basically Homo erectus rather than Homo sapiens. The global expansion of Homo erectus is the first time for human beings to expand outside Africa. This great exploration feat was replicated in modern Homo sapiens nearly 2 million years ago. Driven by climate change, the expansion of grasslands during this period may push them out of Africa. This creates more habitats for herbivores, thus increasing the amount of food.
Modern science has no definite answer as to whether the above statement about the origin of human beings is completely correct. Scientists have found that the emergence of human beings is incredible, and one of the most important miracles is that it only took more than 2 million years for human beings to become intelligent life. This time seems long, but it is too short for the evolution and evolution of a life.
The evolutionary history of life on earth has reached billions of years, among which there are many kinds of hegemonic life, and every time there is a hegemonic life. The most representative is the dinosaur era, which was extinct 65 million years ago. Dinosaurs appeared after the third extinction. From birth to the fifth extinction, it lived for 65.438+0.6 billion years.
1.600 million years. How long is this? But even the dominant creature like dinosaurs, after a long period of 65.438+0.6 billion years, wisdom was not born and became an intelligent life. However, it only took more than 2 million years for human beings to realize the evolution of life into intelligent life. Do you think it is incredible? Are humans special?
In fact, there is nothing special between human beings and other life on earth. In fact, human beings are not as good as some animals in many aspects, such as human beings, whose physique is weak and far less powerful than some animals. But in the end, it only took millions of years for human beings to realize the evolution of intelligent life. Is it really natural evolution?
There are still many unsolved mysteries about the origin of mankind. I believe that the real situation is far more complicated than we thought. It is possible that in the future, when scientists really solve the mystery of the origin of human beings, they will find that our current speculation on the origin of human beings may be completely wrong.
