What would happen if you were born on Mars? Can you imagine?

Humans have been thinking about colonizing Mars for decades, so if they really immigrate to Mars, how can they reproduce on Mars? What would it be like if you were born on Mars? If humans want to settle on Mars, they must be able to thrive on Mars. Some people say that a healthy race needs at least 98 people, while others say that it needs at least 10000 people. But no matter how many people are needed, only a few generations are needed. Martians will be very different from us. Mars is called the twin brother of the earth and the planet most similar to the earth in the solar system, but it is still very different from the earth in gravity, atmosphere and magnetic field.

Babies on earth may have as many as 120 gene mutations at birth. These mutated genes will be passed down from generation to generation, and each generation is more adapted to the local environment than the previous generation. If our technology could edit our own genes at that time, this process could be omitted. You will find that after three or five generations, people on Mars will look very different from humans. The gravity of Mars is only 1/3 of that of the earth, so your bone density will be very loose and brittle. Then the air. The oxygen content in the air on the earth is about 2 1%, while the oxygen on Mars is very scarce.

Humans can't evolve a respiratory system that can adapt to the Martian air, but we can solve it in other ways, such as evolving denser capillaries, which can effectively move blood and transport it to the whole body through oxygen. Even so, humans on Mars have to live underground or in thick insulated rooms to adapt to the bad air. Because being confined to a narrow space for a long time, you don't need to look far, and your vision will gradually deteriorate, so Mars is born with myopia. At the same time, the earth's magnetic field can protect us from the radiation of the sun, and the melanin in our body can also protect us, but the geomagnetic field of Mars is very weak, and the radiation will be stronger, so melanin can't resist it. So our skin will produce more carotenoids, which can slow down the cell cycle and resist skin cancer. They are bright orange like carrots. In other words, Martians have orange skin.

Unfortunately, they can't adapt to the environment on earth by their bodies alone. The gravity on the earth is unbearable for the fragile bones of Martians, and their immune system is not as strong as that of earthlings. The virus on the earth is fatal to them. So if Mars is really colonized in the future, people on Earth and Martians will become completely different viruses.
