Girls are generally shorter than boys - this is so natural around us that we never even question why it happens. In fact, behind this difference are complex biological processes, hormonal fluctuations, genetic instructions, and the imprint of thousands of years of evolution. Human body growth mainly depends on growth hormone and sex hormones. Girls usually reach puberty earlier than boys, and at that time the amount of estrogen hormone in their body increases. This hormone quickly closes the growth plate of the bones, which causes the process of height growth to stop much earlier. The opposite happens in boys' bodies.
They reach puberty relatively late, but then their bodies produce a large amount of a hormone called testosterone. This hormone helps in increasing the length of bones and developing muscles. As a result, boys continue to grow for a long time and their average height is higher than girls.
Not only hormones, but genetics also play a big role in this. The shape and structure of the body are determined according to the genes received from their parents, but the instructions for bone growth in boys' genes are somewhat different. Evolution has also worked with these specific processes inside the body. In the lives of people in the past, physical labor, hunting or war were the main tasks. For which a strong and tall body structure was more suitable. As a result, the body of men has evolved in such a way that they can adapt to these tasks, and this has gradually increased their average height.
However, this does not mean that all boys will be taller than girls or all girls will be shorter. There are always exceptions in nature. But on average, boys tend to be slightly taller than girls. This is not a social discrimination, but rather a calculation of biology itself.
