You and me too are Martians? A serious theory that human ancestry may have come from Mars



"Hometown of mankind isMars"When you hear it, you may feel it is a story in SF or fantasy world. However, according to many planetary scientists, if some kind of "life" (here, it carries genetic information) on MarsDNAYaRNAIf there was a mass of an organic compound containing the same), the possibility that microorganisms as distant ancestors of all living creatures including the human being might have crossed the universe on a meteor from Mars There seems to be many in there.

MITWhenHarvard UniversityA project to develop a device to search for DNA and RNA on Mars to verify this theory is starting by the team of.

Details are as below.Are you a Martian?

Earth and planetary scientists and microbiologists at MIT and Harvard said, "The climate of the Earth and Mars is much closer to the beginning of the solar system than it is now." "A total of about 1 billion tons of meteorites goes from Mars to the Earth "The microorganisms have been found to be able to withstand the impact and heat of such a collision of the meteorite on the planet and there is also a rationale suggesting that you can survive thousands of years of universe journeys before arriving at the planet Based on the facts already shown by many researches such as "There is now", it seems that it has judged that the significance of verifying this "Mars origin theory" is sufficient.

Also, we know that the movement in the direction of flying from Mars to Earth is 100 times easier to occur than meteorite flying from Earth to Mars due to orbital dynamics. Therefore, if there are creatures with DNA and RNA similar to those of the Earth's creatures in the past, if Mars has the same ancestry, it can be of Martian origin rather than Earth origin It can be said that sex is higher.

At present it is the Earth and Mars that look similar but not similar, but "Earth planetThere is only one called Mars, one of the planets that resemble the earth most of several planets.


The team is currently working on a spacecraft equipped with a so-called "biological identification device" named "Search for Extra-Terrestrial Genomes (SETG: Extraterrestrial Genome Exploration)" to dig through Mars' It is under development, which is expected to be completed in about two years.

Why do we need to find and search the ground of Mars? "When searching for life on Mars today, the most likely place is the basement," said MIT's biotechnologistChristopher CarrDr. is speaking. The surface of the present Mars is a state where the temperature is too low and too dry to survive any known creatures, but recent evidence has also found evidence that water existed in the past, There are also survey results suggesting that water as a fluid may still exist.

If there was a creature on Mars, traces of the original organisms that had already been lost on Earth may be cryopreserved in the basement of Mars. By studying the biochemistry of Mars, it may be possible to elucidate the biological origin of humans living on Earth more deeply.

Also, NASA'sAmes Research CenterAstrobiologistChristopher McKayDr. pointed out that this project will have a very important meaning from the viewpoint of astronaut's health and safety and the safety of samples taken back from space, saying, "If Mars is close to Earth's creatures If there are living organisms at the edges, the possibility that the microorganisms are infectious to the creatures of the earth is much higher than if they were living organisms that are alike but not alike.
