Bones are undoubtedly the hardest tissues in the human body, and the hard bones from head to toe support us to stand, walk, and run.
Many people know that the number of human bones is not the same when they are young and when they grow up, because in the process of growing up, some bones are fused together. As a person grows older, there are fewer and fewer bones, from more than 300 pieces and eventually more than 200 pieces.
It stands to reason that human beings are all of the same root and origin, and the number of bones should be the same when they grow up, butThe reality is that most of the yellow people have 204 bones, while most of the Europeans and Americans have 206 bones.
So what are the two differences? Why this difference?
As mentioned earlier, the number of bones in humans is constantly changing from small to large. When a baby is born, there are about 305 bones. As children get older, many bones will close and fuse, and in the end, more than 200 pieces remain, supporting our adult bodies.
The difference in the number of bones between yellow people and Europeans and Americans is the "phalanges".。The phalangeal bone, as the name suggests, is the bone above the toe. The difference is in the number of bones in the little toe. After expert research, the little toe of Europeans and Americans has one more phalange bone than the little toe of yellow people, which is three, while most of the yellow people have two pieces. One more foot has two more feet. So herein lies the difference in the number of bones.
In addition to the phalanges, there is also a theory that there is a difference in the hip bones, and Europeans and Americans have two more cartilages than yellow people, but I think this statement is not very reliable, and the phalanges are more credible.
The difference between the phalanges is actually only a small difference, and there are no special features, and the difference in the bones on the toes does not affect the actionSo why the difference?
In fact, it is mainly an evolutionary factor. The mainstream theory in the academic community is that early humans originated in Africa, and later due to environmental changes, in order to chase prey, early humans began to go out of the African continent, and some of them went north to Europe, becoming the ancestors of Europeans and Americans; The other part went to Asia and became the ancestors of the yellow race.
Because Europe is mountainous and hilly, in order to adapt to climbing and running, Europeans and Americans need extra little toe bones to balance their bodies, and then be able to chase prey over mountains and mountains. Different from the hunting and nomadic survival mode of Europeans and Americans, the yellow people slowly evolved into an agricultural civilization and adopted farming, breeding and picking as their own way of survival.
Since the yellow race has a more advanced way of living and rarely needs to climb and run, the yellow man's third little toe bone slowly evolves away, because the yellow man is able to get more with fewer resources.
All in all, the difference in the number of bones between the yellow race and Europeans and Americans is affected by the natural environment and the way of survival, from the perspective of evolution, it should be that the fewer bones the better, from the human beings from ancient times to the present, from small to large bone changes can be seen, the trend of evolution is less and less bones,So from a certain point of view, the yellow race should go further in the process of human evolution.
