evolutionism
Darwin's theory of evolution says: natural selection, survival of the fittest. Only by adapting to the ecological environment can we survive better, and all the creatures that do not adapt to the ecological environment in history will eventually become extinct. Even if it is such a powerful creature as the dinosaurs, in the end, it is not to perish, it is the extinction of the dinosaurs, human beings have the opportunity to grow into the new generation of overlords of the earth,
Since it is a matter of natural selection and survival of the fittest, there is a problem that plagues many people, Chinese only has 204 bones, why do Europeans have 206 bones? What is the reason why Europeans have two more bones than Chinese?
Chinese 2 fewer bones than Europeans
Scientists have found that in fact, the number of bones in the human body varies greatly with age. For example, the number of human bones in infancy and toddler is about 305 pieces, when it comes to adolescence, the number of bones in the human body decreases to about 218 pieces, and then in adulthood, the shape and quantity of bones are basically fixed, stable at 206 pieces. (This data was discovered by foreign scientists, and in fact, Chinese the bones stabilized at 204 pieces after adulthood.)
First of all, we need to know which part of the bone we have two less bones than the Europeans. Studies have shown that Europeans have 3 small toes, while Chinese have only 2, and each foot has one less bone, adding up to a total of two fewer bones.
So why do Europeans and Americans have two more toe bones than we do? Scientists have analyzed this from the size of Europeans, europeans are generally tall and heavy, so in the process of evolution, more toes are retained to achieve the purpose of higher weight.
China is small in size, so two toes have merged into one in the process of evolution, so Chinese two toe bones less than Europeans and Americans. In fact, many scientists believe that merging Chinese toes is a higher evolutionary behavior. Ancient humans have a total of more than 300 bones in adulthood, which have undergone hundreds of thousands of years of evolution, and many parts of the bones have merged with other bones, and this process itself is an evolutionary process. So Chinese two fewer bones than Europeans is also an evolutionary process.
