How does the human body change when living on Mars?

In many fantasy films, people born on Mars will have weaker bones than normal, so they won't tolerate gravity on Earth.

NASA is hoping that humans will colonize Mars for the next 30 years. Technology billionaire Elon Musk is much more confident with a 10-year figure and poses a scenario: one is to stay on Earth and will be extinct after an ice-age event, the other is to settle in many other planets. .

The climate on Mars is very different from Earth.

The Martian climate is not like Earth at all: lower gravity, strong radioactivity, no microbial environment. All of this will impact and make the generation of people on Mars evolve at a record rate since starting to walk from two feet to now.

Specifically, pregnancy and childbirth will be much more difficult. Space simulation in mice shows that the number of embryos will be harder to form, and it is likely that there will be a different body structure due to natural selection to adapt to the environment.

Gravitation

Gravity on Mars is only 1/3 of the Earth.

Gravity is only 1/3 of the Earth will reduce bone density from 1-2% per month, only half after 2, 3 years, and especially fast for pregnant women because they need very large amounts of calcium. Decreased bone density makes bones more vulnerable, such as broken hip and spine. Only people with large bone density can survive, and gradually humans on Mars will have a much larger bone mass than their ancestors.

Radiation

High level of radiation. It is estimated that in 2 years, people living on Mars will be subjected to six times the radioactivity of the US standard. Without effective prevention, radiation affecting DNA will cause mutations that lead to cancer, increase the rate of cancer for Martian residents, and accelerate the evolution process by creating mutations. Random genetics may be beneficial.

Various Mars radiation stimulates the creation of new skin colors.

For example, mutations increase the melanin pigmentation in the skin to prevent radiation, as melanin will neutralize radiation to avoid gene effects, and so Martian residents will have darker skin than any other strain on the left. land. On the other hand, diverse radiation stimulates the production of new skin colors, such as orange from carotenoid pigment against solar radiation.

High levels of radiation also affect the brain, memory and human behavior. However, natural selection will filter out healthy individuals and create a generation with good health, with the ability to discover more distant, harsher planets.

Microorganism

Microbial bacteria have a great influence on human life.

Finally, micro-environment. Microbial bacteria have a great influence on human life, typically intestinal probiotics. Children on Mars will not be exposed to this bacterium, leading to many disadvantages including poor metabolism, reduced resistance to common diseases, increased risk of type 1 diabetes, allergies and asthma. asthma and some types of cancer. Experiments in rats and rabbits showed that their immune and neurological systems were misaligned, and that the synthesis of food substances was also misleading.

Therefore, people living on Mars consume only certain types of sugars, proteins and fats without bacteria. On the other hand, it is hoped that some microorganisms will follow humans to Mars, grow faster under the influence of mutations and development. Plants that are brought along are also likely to grow in this way.

Types of illnesses

Sketch the Martian.

Diseases such as Ebola and Zika will be difficult to follow people to Mars, causing the Martian population's immune system to disappear completely, and they will be life-threatening if exposed when returned. Earth or human pathogen from the earth visit. The types of contact from normal to sexual are very risky.

So when completely isolated, a different and harsh natural environment can create a completely new type of person. This process is estimated to take about 6,000 years due to the apparent contrast between the two planets. The new breed may be as true as the "The Martian Chronicles" fiction novel, with brown skin and golden eyes.
