What is the upper limit of human height?

From ancient times to the present, height has always been something that people care about very much. Take a look at the "Romance of the Three Kingdoms" that we are familiar with. Every time a remarkable character appears, his height is reported. Cao Cao is seven feet tall (1.617 meters), Liu Bei is seven feet five (1.725 meters), Zhang Fei is eight feet tall (1.84 meters), and Guan Yu is nine feet tall (2.079 meters).

According to the Guinness Book of Records, there are several "giants" in the world, such as Robert Pershing Wadlow from the United States, who is 272 cm tall, Leonid Stadnik from Ukraine, who is 257 cm tall, and Bao Xishun from China, who is 236 cm tall.

From this perspective, no one's height can exceed 3 meters. So, have you ever thought about the maximum height of human beings?

When biologists were studying the 23 pairs of chromosomes in the human body, they discovered an abnormality in chromosome 17. On chromosome 17, there is a gene called P53, which can specifically inhibit gigantism in humans.

If we change this gene, can we break the current height bottleneck of humans?

The P53 gene is an important anti-cancer gene. Its wild type causes cancer cells to undergo apoptosis, thereby preventing cancer. It also has the function of helping cell genes repair defects. In simple terms, P53 synthesizes proteins that can specifically detect whether gene transcription is abnormal. Once a problem is found, it will be processed, either repaired or destroyed. Therefore, if p53 is changed or mutated, it will increase the chance of cancer.

Seeing this, the answer is obvious. The existence of all our lives is determined by genes, and genes are the controllers of life. Once genes are forcibly changed artificially, the consequences will be disastrous. For thousands of years, there have been no particularly obvious changes in human body functions or other aspects. From this point of view, human height has now reached its limit. What do you think about this? Welcome to leave a message in the comment area.
