ClassX Video Lessons Youtube Channel Science Time The Generation of Superhumans – Can We Edit Our Genes?
Superhero movies and comics, like X-Men and Spider-Man, have long fascinated us with the idea of possessing superhuman abilities. Throughout history, many cultures have believed in individuals with extraordinary powers. Today, the pursuit of exceptional performance is evident, with some people turning to performance-enhancing drugs or rigorous training to push their natural limits.
In sports, athletes often demonstrate remarkable levels of strength and speed, pushing the boundaries of human capability. Interestingly, all humans share 99.9% of their genetic makeup, with the remaining 0.1% accounting for our unique traits and abilities. Recent technological advancements have enabled scientists to pinpoint genetic variations that contribute to these extraordinary capabilities.
There is a growing interest in identifying genes linked to special abilities, many of which are inherited. Dr. George Church, a geneticist at Harvard, is compiling a list of genetic mutations that could potentially lead to superhuman traits. For instance, the myostatin gene and LRP5 alleles can enhance bone strength, while the PCSK9 gene is associated with lower LDL cholesterol levels, potentially reducing the risk of heart disease.
While society is captivated by the idea of superhuman abilities, some individuals possess remarkable capabilities due to a combination of genetics, training, and adaptation. Although their abilities may not match those of fictional superheroes, they are nonetheless impressive.
For example, the MSTN gene is linked to incredible strength. Eddie Hall, the 2017 World’s Strongest Man, has a genetic mutation that results in myostatin-related muscle hypertrophy, contributing to his significant muscle mass.
The Bajo tribe, known as sea nomads, can hold their breath underwater for up to 13 minutes at depths of around 200 feet. This ability is a genetic adaptation, allowing them to develop larger spleens that store oxygenated blood, enhancing their underwater endurance.
Dutch extreme athlete Wim Hof, also known as “The Iceman,” has gained attention for his ability to withstand extreme cold. His skills are not attributed to genetics but rather his ability to voluntarily influence his autonomic nervous system, a feat once thought impossible. Hof has set numerous records for cold exposure, including climbing Mount Kilimanjaro in shorts and running a half marathon barefoot above the Arctic Circle.
Research on supercentenarians—those who live to 110 years or more—shows that they often remain free from major age-related diseases until the end of their lives. Scientists are exploring ways to delay aging, which could significantly impact health and longevity.
Advancements in genetic engineering, such as CRISPR technology, offer the possibility of altering our genetic makeup. This technology allows for the modification of specific genes, suggesting that our genetic destiny may not be as fixed as once believed. As technology progresses, targeted changes to our genomes could become feasible.
Human populations continue to evolve through natural selection and genetic drift. The genomic revolution enables researchers to observe changes in the human genome in real-time, opening new avenues for research and development. If engineered correctly, radical changes in the genome could lead to extended life expectancy and enhanced abilities.
However, the ethical, legal, and moral implications of genetic engineering are profound and must be carefully considered before proceeding with such advancements.

Superhero movies and comics, such as X-Men and Spider-Man, have captured the fantasy of being superhuman. Many cultures throughout history have believed that certain individuals possess special powers or abilities that elevate them to superior beings. In contemporary society, many people strive for exceptional performance, with some resorting to performance-enhancing drugs, engaging in obsessive behaviors, or attempting to enhance their natural abilities through focused practice.
In the realm of sports, some athletes have pushed the limits of human capability, demonstrating superhuman levels of athleticism and speed. All human beings share 99.9% of their genetic makeup, while the remaining 0.1% contains crucial information about our individuality, strengths, and weaknesses. In the past decade, advancements in technology have significantly improved scientists’ ability to identify genetic variations that differentiate our DNA from that of others. In some cases, these genetic differences contribute to extraordinary abilities.
There is a growing interest in identifying genes associated with special abilities, many of which appear to be inherited. Dr. George Church, a Harvard professor and geneticist, is compiling a list of genetic mutations and alterations that could lead to superhuman abilities. For example, the myostatin gene and LRP5 alleles can enhance bone strength, while PCSK9 is associated with lower LDL cholesterol levels, which may reduce the risk of coronary disease.
As a society, we are drawn to the concept of extraordinary abilities. However, there are individuals whose exceptional capabilities result from a combination of genetics, training, and adaptation. While their abilities may not resemble those of fictional characters, they are nonetheless remarkable.
For instance, scientists have identified genes responsible for incredible strength, such as the MSTN gene, which, when expressed in a typical individual, results in significantly stronger muscles. Eddie Hall, the 2017 World’s Strongest Man, possesses a genetic mutation that leads to myostatin-related muscle hypertrophy, contributing to his substantial muscle mass.
Members of the Bajo tribe, often referred to as sea nomads, can hold their breath underwater for up to 13 minutes at depths of around 200 feet. Research indicates that this breath-holding ability is a genetic adaptation resulting from natural selection, allowing them to develop larger spleens that store oxygenated blood, thereby increasing their endurance underwater.
Dutch extreme athlete Wim Hof, known as “The Iceman,” has gained attention not for his genetics but for his skills. His ability to endure cold has been studied and appears to stem from his capacity to voluntarily influence his autonomic nervous system, a feat previously thought impossible. Hof has set numerous records related to cold exposure, including climbing Mount Kilimanjaro in shorts and running a half marathon barefoot above the Arctic Circle.
Research on supercentenarians—individuals who have reached the age of 110—reveals that they often remain free from major age-related diseases until the end of their lives. Scientists hope to discover ways to delay aging, even marginally, which could significantly impact health and life expectancy.
Advancements in genetic engineering, such as CRISPR technology, may allow us to alter our genetic makeup. This technology enables the modification of specific genes, suggesting that our genes may not dictate our destiny as previously thought. As technology evolves, it may become possible to make targeted changes to our genomes.
Anatomically modern human populations continue to evolve, influenced by natural selection and genetic drift. The genomic revolution allows researchers to observe changes in the human genome in real-time, opening new avenues for research and development. If engineered correctly, radical changes in the genome could lead to extended life expectancy and enhanced abilities.
However, the ethical, legal, and moral implications of genetic engineering are significant and must be carefully considered before proceeding.
