The "rarest" species among humans has only more than 3,000 people left. What makes their numbers so rare?

The rarest species currently known to mankind is "red-haired people". There are only about 3,000 people in the world, because "red-haired people" are not a unique racial group, they are just genetic mutations. The product of "red-haired people", so the number of "red-haired people" is not very large, and they are distributed in all corners of the world, and it is difficult to get together. Therefore, the number of "red-haired people" is difficult to increase, but it will not become extinct.

The world is so big that it is full of wonders. Did you know that not only are many rare animals and plants in the world on the verge of extinction, but humans are also facing endangered races. Many people know that there are yellow and white people in the world. There are many racial groups such as black people, but there is one kind of people that is not very common, they are "red-haired people".

In fact, "red-haired people" are not a specific racial group, they are some hidden people. If the sex gene mutates in the human body, people of any race may mutate into "red-haired people", but the probability is very small. People who carry this red-haired gene are mostly distributed in European countries, but they are not red-haired. , this kind of recessive gene is not rare, but it is difficult to mutate. Perhaps, only when all people carrying this recessive gene disappear, will "red-haired people" truly become extinct. Otherwise, "red-haired people" will never be It will not disappear, it will just be very rare. The obvious characteristics of red-haired people are red hair, blue eyes, and freckles on their faces. Many people who have seen them describe them as having flame-like hair. With beautiful sapphire eyes, they are like princes and princesses from cartoons. Although some people think that the obvious freckles on their faces are not very good-looking, there are also some alternative people who admire them very much. They are photographers. A photographer took a photo album of red-haired girls with freckles. He praised these "red-haired girls" as the darlings of the modeling industry, being dazzling but not ostentatious. He also hoped that more people could appreciate and protect their beauty.
