Why men are taller than women or the “tall” gene
How many of you have ever wondered why men are taller than women and how this happened? Unfortunately, modern science cannot give a definite answer to this question, but, nevertheless, it has put forward several interesting and very plausible theories. Read this article and choose the most fascinating theory for yourself.

Some statistics
Absolutely, in every city, in every country in the world, if a man or woman asks you a high question, a man will answer you. However, there are statistics that confirm that there is no need to conduct such strange experiments and that strangers do not need to ask stupid questions.
For example, in China, the average height of men is about 1 meter 70 centimeters, and the average height of women is 1 meter 58 centimeters. In Russia, the height of men is about 178 centimeters, and women — 166. In Norway, the height of men is 182 centimeters, and women — 168. In Mexico, the average height of men is only 169 centimeters, and women — even less, about 154.
As can be seen from statistics, the average height of people in different countries can vary greatly, but one thing remains unchanged: men are always on average 15 centimeters taller than women. Of course, you can say that you know women who walk down the street and honk their heads painfully. But statistics show the average height of people, and if there are such women, then somewhere there must be men who respond to these signals with their heads.
And from all this we can conclude that people’s height depends on their country of residence and part of the planet. And this conclusion smoothly leads to the first theory about why men are taller than women.
Let”s go back to the roots
Research by many scientists has shown that living conditions, work, health and especially nutrition are very important factors in the growth of any living organism. Thus, if a person does not receive enough food, the brain allocates energy precisely to maintain the organism”s lifespan, but growth stops.

Our existence is full of stereotypes, and there are countless beliefs about men and women in the world, including popular belief.
Some scientists also suggest that males” greater height may give them an advantage in competition with other males, such as when hunting.
Everyone knows that when mammoths walked the earth, people did not yet know how to cultivate the land. The only source of food was hunting. And, as they knew, it was a man. Therefore, being taller and taller may be a direct inheritance from our ancestors.
Additionally, men needed to eat more to stay in shape, and he had more options to do so. This led to so-called food discrimination, which negatively affected the development of women.
However, if earlier it was a matter of life and death, now it is more of a social order. As was allowed, people do not understand this. Stereotypes say that girls should eat less than boys, but from childhood they turn out to be no worse than the stronger sex in activities.

Gene is the head of everything
The next theory that tries to answer the question “why are men taller than women” has to do with genes and their differences.
Growth is influenced by a number of factors. These can be natural, external, internal and especially genetic factors. Everyone knows that if parents are tall, then their children will most likely not be deprived of it. From this we can conclude that certain genes can influence height, but, unfortunately, which genes have not yet been determined.
One of the answers to the question: “Why are men taller than women?” was proposed by scientists from the University of Helsinki. According to them, it all comes down to the X chromosome, or rather to the fact that women have two X chromosomes, while men have one X chromosome and one Y chromosome. As a result of the study, scientists discovered the ITM2A gene on the X chromosome.
According to experts, this gene is more or less involved in growth and cartilage development, and the longer it develops, the taller a person is. However, according to scientists, one of the variants of this gene can lead to short stature. This means that if the ITM2A gene works intensively at a certain level, then the growth and development of cartilage tissue is hampered, which leads to growth arrest.
Because women have two X chromosomes, this gene functions twice as hard, which may be the reason why women stop growing earlier than men. Also, girls aged 10-11 years will be taller than boys of the same age, but by the age of 14-15 years, growth begins to slow down, while boys continue to grow actively.
What will happen if women are taller than men? Noma or not? You can find more detailed information in the article at the link.
