A new theory has been put forward about Mars, one of the structures believed to be suitable for life in the solar system. Scientists, in their article published in the journal Nature, ancient microbial life claimed to cause climate change.

Scientists have these theories 3.7 billion years ago He produced it using a model that simulates microbes living on Mars that consume hydrogen and produce methane. At that time, Mars’ atmospheric conditions were the same as Earth’s that day.

But microbes from Mars took a different path than microbes on Earth:

ancient microbial life on Earth, preparing the conditions necessary for today’s living beings played a major role. Microbes have created an environment to help them thrive. But according to the simulation, the situation was different for microbes on Mars: it is just at the beginning of the road. they made their own end.

According to the model, this is due to the gas composition of the two planets and their distance from the sun. Mars, which is farther from the sun than Earth, maintains temperatures suitable for life. carbon dioxide and hydrogen dependent on heat-trapping greenhouse gases such as:

Ancient microbes on Mars also consumed hydrogen, a potent greenhouse gas, and produced methane. So microbes slow heat trap blanket they consumed the layer that served as eventually Mars became so cold that advanced life forms could not form.

When Mars’ surface temperature drops from the tolerable 10 to 20 degrees Celsius to -57 degrees, microbes began to flee deeper into the planet. So much so that within hundreds of millions of years, microbes had descended 1 kilometer below the surface of the planet.

The new theory of scientists is currently: without proof case. NASA’s Curiosity spacecraft has previously found traces that could be evidence that microbes still exist on Mars. However, traces of methane gas have also been found by satellites in the Martian atmosphere. To prove the theory, it is necessary to find out if any of these ancient microbes survived.

Fossils or living specimens of ancient microbes can be found in the low and middle plains of Mars, according to scientists.
