After careful study, it is not difficult to find that there are quite a few half toenails. And not only in China, but also in Southeast Asia and East Asia, there are people with the smallest toenails and two halves of toenails. In fact, there is a proper term called petaloid nail. According to incomplete statistics, more than 60% people in China have petal-shaped nails, so why are petal-shaped nails common in Southeast Asia but rare in Europe and America? Is this about health?
02
Actually, it's not. The genes of people in Southeast Asia and East Asia are very similar, which means we all have the same ancestor. Petal nails may be genetic changes of previous ancestors, which led to such characteristics in their descendants. This has nothing to do with health. In other words, people with and without petal nails actually have no health problems. Maybe petal nails don't look so good. But it's really no different from people without petal nails.

So petaloid nail is not a disease, it is a disease, it is a genetic mutation, which has both good and bad sides. But this petal-shaped nail has no effect on our physiology and psychology, and the change of direction may be due to the habits of our ancestors. A little habit of people in the past may change the physical structure of people in the future, depending on what occupation your ancestors used to engage in. These changes may be helpful to some occupations of your ancestors. You may not need them now, but your ancestors may actually be able to use them. So why do Europeans and Americans rarely have the characteristics of petal-shaped nails? Most people know that Europeans and Americans are big and in good shape, so some people may doubt it. Because Asians have the characteristics of petal-shaped toenails, while Europeans and Americans rarely have them, they think that half-nails have something to do with physical condition, but in fact, our physical relationship, or morphological characteristics, is mainly influenced by the environment, and our toenails will behave differently in different environments. Maybe the toenails of Europeans and Americans are different from ours.

If in summer, many people may not be satisfied that their toenails are split in two, after all, it is really beautiful, but we should consider that our most important part is our physical condition. All our actions are based on our healthy bodies. Whether the smallest toenail is split in two has nothing to do with health, as long as we know.
