8 Oddities of Your Body That You Inherited From Your Ancestors

There are 46 chromosomes in every human cell. All information about us is recorded on them: height, eye color, blood type, diseases, and much more. However, not only physical appearance but also character traits can be inherited from parents.

So, what features we inherit from our ancestors? It turns out that not all the oddities of our behavior depend on education and lifestyle.

Insomnia

Insomnia or other sleep disorders can be caused by various circumstances, such as stress, anxiety before an important event or illness. But if you have been having trouble sleeping for a long time, then perhaps the reason is in the genes.

In 2015, the American Academy of Sleep conducted a study and found out that insomnia can be inherited. 

The ability to control yourself

Aggression and impulsivity are not always associated with education. Perhaps you inherited these character traits from your ancestors, and the “warrior gene” controls your emotions.

A group of British scientists found that the discovered gene does not make a person over-emotional in everyday life. They become assertive only in stressful situations. And this can be perceived as aggression.

Craving for sweets

Addiction to sweets is not a sign of a lack of willpower. For this habit, you can thank your heredity. The FTO gene can block the feeling of satiety and increases the desire to eat something sweet. It affects the work of hormones that are responsible for hunger and the desire to seek food. In people with this gene, fat is deposited mainly on the hips and waist.

Unfortunately, it can be obtained from both mom and dad. If you inherited this gene from both parents, then the chances of being overweight are 70%, and those who have inherited one copy of the gene have 30%. Maybe that’s why it is very difficult to get rid of cravings for sweets.

Teeth and jaw structure

A lot of factors affect the condition of the teeth – a way of life, nutrition, bad habits. But it can also be heredity. Dad’s genes are more responsible for the structure of teeth than the genes of a mom. They form the size, shape, curvature, bite, the thickness of the enamel, and even the structure of the jaw. If the father is a frequent dentist client, then the children are likely to be the same.

Driving skills

California Institute neuroscientists say bad driving can have hereditary prerequisites. The BDNF gene is to blame. Owners of these gene are 20% worse at passing a driving test. Repeated tests give a similar result. Such drivers more often forget the rules of the road, make more mistakes during the trip, and they are less careful on the road.

Addiction to music

Nokia not only produces mobile phones but also conducts marketing research. In 2009, the influence of heredity on musical taste was revealed. A study by Heriot-Watt University involved 4,000 twins. Scientists have found that our musical preferences are due to genes by 55%, and the desire to listen to music – by 25%.

Pain sensitivity

Everyone has a different pain threshold – someone higher, someone lower, but normally everyone feels it. There are several genes that affect our ability to endure pain. Some dull it, others strengthen it, and others completely turn it off.

Stephen Pete and his brother were born with complete insensitivity to pain, just like the Italian family of Marsilla (mother, daughter, her 2 sons, sister, and niece). Because of their characteristics, these people need to see doctors more often and take tests. After all, it is very easy for them to miss inflammation or injury.

Love for dogs

In 2019, scientists from Uppsala University (Sweden) examined 85,542 twin pairs and found that we have genetically embedded love for dogs. Approximately 50% of the owners of four-legged friends got pets due to their heredity. It is not yet clear which genes are responsible for the choice of an animal, but in the future, this study will help solve the problem of allergies to dogs.
