From today's point of view, the changes in human genes have already occurred as early as the separation of the Eurasian continental plates. Since the Qin dynasty, the height of Asians has actually been decreasing, which may be related to the natural climate and historical changes at that time. Europeans and Americans are of Caucasian descent in most cases, so in the cold climate with relatively high latitude, the tall and straight figure has become their symbol.

The influence of this gene has appeared since the fetal period. For children in China, the proportion of legs is higher than that of Duan Dan in Europe and America, and many children have short heads and thighs when doing pregnancy tests, which is very common in China. You know, their so-called standards are actually formulated according to the fetal standards in Europe and America.

From the same point of view, as long as the dietary differences between China and Europe and the United States are involved, people in China are relatively vegetarian, and they rely more on it as a compound and vegetable for tea nutrition. Europeans and Americans always like to eat meat instead of meat, and eat a lot of steak, chicken chops, fish chops and other foods. In this case, the bones and muscles of Europeans and Americans grow much faster than those of China, so their high-protein diet structure also makes their nutrition more beneficial to their health.

Sometimes we have to admit that genes are terrible. In fact, sometimes many people have decided what they want before they are born. These can only be happy with the times. After all, our bodies are only given by our parents, and our souls can be shaped slowly in this life.
