45 Times Human Genetics Created Very Unique Physical Traits

The most influential effect of mutation is its role in evolution. Without these changes in DNA, organisms wouldn’t be able to develop further. Genes in certain or different conditions can improve themselves to help the organism adapt. If proven successful, they can be passed on to other generations.

Contrary to common conceptions, human evolution hasn’t stopped. In countries without good healthcare, people who survive infectious diseases can pass on their genetic resistance to their offspring. DNA evidence shows growing resistance to illnesses like malaria and Lassa fever, which saves people’s lives every year. We may also be adapting to unhealthy diets, as our blood pressure and cholesterol are lowering as a response to our fat and sugar-induced diet.

Some genetic varieties have become so common that we don’t consider them to be unique anymore. The mutation that gives people blue eyes is actually quite recent in the history of humans. This change in genes removes the brown pigment from the iris and makes it blue. Researchers were able to trace it back to the first time it occurred in a Spanish person who lived a mere 7,000 years ago.

Red hair is also among the most well-known genetic varieties that people have. While we all might know a person with fiery locks, they are still pretty rare, as only 5–8% of people have this feature.

Unique genes have very useful effects on an individual’s well-being. For example, most people in the world are lactose intolerant, but due to mutations, it has become possible for them to digest dairy. Lactose-tolerant individuals often originate from northwest Europe and some parts of Africa, where farming became a major source of food.

Additionally, some gene mutations explain why some people don’t get sick. Numerous people have avoided catching diseases during COVID-19, HIV, and other outbreaks. Hyperimmune people can be studied to discover medicines and new ways to treat diseases.

Numerous superheroes in comics, books, and cinematic universes attribute their magical abilities to genetic mutations. Even though it’s largely fictitious, there are specific genetic variations that allow us to have some “super qualities”. For example, a LRP5 gene mutation can increase bone density to the point where it becomes impossible to break them. The bones are known to crack baseball bats and withstand car wrecks.

People with the “short sleeper” mutation naturally need only four hours of sleep to feel totally energized. The lucky 1% of the population can sleep less than the recommended seven to eight hours without feeling sleep deprivation.

A mutation that’s just for the ladies allows them to see a wider range of colors. Known as tetrachromacy, it’s present in about 12% of women, giving them “supervision” to see hues undetectable by other people. That’s why sometimes for men, “all the colors look the same,” while women can’t choose their favorite one.

Moreover, the “sports gene” mutation gives people super speed because it controls fast-twitch muscles, allowing them to flex faster for running and other physical tasks. A study in 2008 found that the majority of top runners and athletes have this mutation. Well, it seems that sometimes it all comes down to your DNA.

It’s truly mind-boggling how various mutations can be intertwined in our DNA. They help us adapt, provide us with super qualities, and give us unique looks. If you’re looking for more publications about people with unpredictable genetics, you can check them out here and here.
