The person with the highest intelligence on the planet we live on is human beings, and people have always had a very in-depth study of the history of human development and evolution. In particular, many researchers have made a series of efforts to figure out when we humans appeared. In the process of life on Earth, a large part of it is the study of our human evolutionary history. Although there has been a persistent study of the various situations in the early days of mankind, there is no more completely accurate answer to what the earliest human beings looked like, and what we now know is that the earliest human beings developed from those apes.
There is a saying in the field of science that as early as 65 million years ago, the planet we live on was hit by an external meteorite, and in the course of such an event, the perpetrator was a meteorite of a width of about 10 kilometers, which fell on the Yucatan Peninsula of present-day Mexico when it hit our planet, and in this event, a huge disaster was created for the planet, and the dinosaurs who were the rulers of the entire planet suffered a devastating blow. In addition to this creature suffering extinction, 2/3 of other animals have also been extinct. After such an event, the golden age of reptiles on the planet was over. The oldest primitive mammals, after a very long and difficult environment, were eventually bred and entered a state of rapid evolution.
If the history of the earth's development is pushed back more than 50 million years, that era is a state of rapid evolution of many primates, many low-level primates have undergone rapid growth and evolution, and these organisms have also transformed into early apes in the process of continuous reproduction. The ape is a creature that emerged between about 33 million and 24 million years ago, and this creature is bred from some monkeys of the old era.
In the process of the continuous reproduction of these ape creatures, their footprints have become more and more extensive, and researchers have found through the study of these creatures that the proto-Consur ape that originated in East Africa is now considered to be the ancestor of humans and African apes. The ape creatures that live on the earth now mainly come from two regions, one is the African ape, the other is the Asian ape, the two kinds of apes are actually very different, but they diverged about 12 million years ago to 15 million years ago.
After studying the initial development of human beings, it has been found that if you want to understand the earliest forms of human beings, you may be able to understand the living conditions of Austrian apes 12.5 million years ago. Originally living in the forest, these apes are now extinct, reaching a height of about 4 feet, and it is a creature between monkeys and chimpanzees. After in-depth research on the environment and food sources in which this creature lived at that time, it was found that this ape actually ate a variety of fruits. We all know that when humans eat a lot of sugary foods, they will have bad teeth, and this creature may also have dental problems after eating a lot of fruit at that time.
In fact, the latest study found that as early as 12.5 million years ago, such creatures had broken teeth. In the course of studying a dryopithecus named lkm-pal 5508 found near Svetifan, Austria, the researchers discovered that there was a deep lesion in the left molars of this remnant, which took many years to develop. By studying it, it was also found that there were some signs of wear on the right dentition, from which the scientists also deduced that the creature was also experiencing toothache at that time.
We all know that the problem of tooth decay is often possessed by humans, but this phenomenon is extremely rare in the relatives of apes, and it can be understood from the data of previous studies on many ape organisms that only 1.38% of the permanent teeth of those chimpanzees have hollows. We humans account for 92% of dental problems. The most fundamental reason for this phenomenon is the intake of sugar, when there are some bacteria in the mouth, the sugar is converted into organic acids, these organic acids will destroy the tooth enamel and dentin of the teeth. The more sugar substances you consume, the more your teeth decay. When researchers studied wild apes, they found that most wild apes do not often eat sugary fruits. It was only in this state of life that the early apes lived in forests with very rich fruits, which led to the problem of tooth decay in some primitive apes. In fact, researchers learn a lot about what was going on through such a 12.5 million-year-old cavity.
