Why Do Black People Have Big Lips?
The question of why do black people have big lips has been a topic of discussion for many years. Although a number of factors are involved in determining why certain people have larger lips than others, there is also a certain degree of genetics. Luckily, there is some information that is available to help us understand what can be done to reduce the size of our lips.
Men of Africa Descent Had the Largest Total Lip Volume
The lips of black people have a tendency to be big. This is because they have been exposed to the heat and harsh climate of Africa. During this time, they had to breathe in air to cool down. Moreover, they were subjected to ferocious animals and the full force of the sun. They need big lips to survive. In fact, big lips are considered to be the default human lip shape. Moreover, they are regarded as the most attractive. But if you are from a different culture, you may have a hard time adjusting to this new environment.

The study looked at a total volume of the mouth. They also compared the dimensions of the mouth and pharynx (a little pocket behind the flaps of the throat). The researchers found that the lips of africa men were the largest, and the oral cavity of African American men were the smallest.
Thin Lips Are a Genetic Characteristic of Europeans
Many Europeans believe that thin lips are a sign of their ancestry, but what is the science behind this phenomenon? The reason is simple – they are actually a result of genetics. There are genes responsible for everything from skin color to lip shape. This includes a gene that explains why lips are thin in some individuals, while they are not in others. Some people also have a gene that helps them form tube-shaped tongues.
One nifty feature of thin lips is the fact that some people can roll their tongues. This is a feat of genetics that has been observed in humans for centuries. However, it was Alfred Sturtevant who first noted that the same gene also helped people form tube-shaped tongues.
Tropical Areas That Are Not Black Also Tend to Have Larger Lips and Nostrils
A recent study examining the similarities and differences in noses between Africans and those from tropical areas indicates that the evolution of the human nose may have been an ecologically selective process. For instance, the more humid and warm a tropical area is, the more likely people are to breath through their mouths, whereas in cooler climates, they are more likely to breathe through their nostrils. This is not the case in East Africa, where the vast majority of people do not have large nostrils and lips. The reason for the difference is that those from warmer locales have larger genes that allow them to survive in such conditions.
Chapped Lips Are Possible in Certain Locations
Chapped lips may be caused by medical conditions or a lack of moisture in the skin. It is important to consult with a dermatologist for a diagnosis. If a patient has severe chapped lips, they may develop a rash or infection. However, these symptoms are usually temporary.

Chapped lips are common in people living in a dry or cold climate. Chapped lips may also occur due to sun exposure or licking. Having a humidifier installed in your home can help keep the lips moist.
Chapped lips are characterized by a red rash around the mouth. The rash may be dry, flaky, or it may appear red and dry. Sometimes, the lips turn bloody or may even become cut. This is a warning sign that a person is dehydrated and should seek immediate medical attention.
Lips are thinner and less water-resistant than other parts of the body. Because they are not protected by oil glands, they are prone to drying out. Moreover, lips are more exposed to elements, such as the wind and cold. In the winter, there is a higher risk of dryness and chapping.
A variety of inflammatory and allergic conditions can cause chapped lips. Besides, the presence of a yeast infection can also lead to chapped lips. These conditions can be cured by applying lip balm or applying moisturizer.
Children with frequent licking of their lips are at a high risk of developing chapped lips. If your child has these symptoms, try wiping the mouth dry or reminding the child to stop.
Cheilitis is a type of inflammation of the lip skin. Cheilitis is often related to infections or vitamin deficiency. Symptoms include rapid breathing, low blood pressure, and cracking of the lips.
Some forms of cheilitis can be more serious. Actinic cheilitis, for example, is a precancerous condition. People with psychiatric disorders and diabetes are also susceptible to cheilitis.
A doctor can rule out any serious conditions and give you treatment options. Treatment is often based on a combination of a topical cream or ointment and behavioral approaches.
