The origin of life. Who has not ever theorized about it? There are many theories that run both in the scientific community, as well as on the internet and from word of mouth of the billions of inhabitants of the world. One of the curious theories about the origin of the human being is the Panspermia theory. Have you ever heard of her? It is a theory based on the fact that the human being could have another origin different from that of this planet. That is, we can come from another part of the universe.
Could you think that the human race has not developed after the other species of the genus Homo after evolution and come from another part of the universe? In this post we tell you all about the Panspermia theory.
What is the Panspermia theory based on?
This theory thinks that we may have been conceived in another area of the very great universe (or infinite as many scientists claim). And there are many theories and ways that we can come from. As much as it is studied over time, it is something that we can never know with a level of certainty of 100%.
In Panspermia it is said that the human being can be an organism developed in other areas of the universe and whose genes have entered planet Earth through comets or meteorites impacted on the earth's surface. It is possible that, in this way, the growing need to want to know what is happening outside the planet can be explained.
Ever since science and astronomy have developed, human beings have been eager to know what is outside our planet. Therefore, try to make trips to the moon, Mars or to know what types of planets there are so much in our Solar system as beyond the Oort Cloud. Perhaps all of this stems from the need to "go home."
And it is that this theory thinks that human life has reached planet Earth through living microscopic forms that could have developed thanks to the habitable conditions of our planet. We have been able to come from outer space thanks to the impact of meteorites and comets. once introduced to the planet, evolution made the human being develop as we know it today.
Types of Panspermia
There are several types of Panspermia that some scientists defend as the origin of life on Earth. It is known as natural and directed panspermia. We are going to analyze each of them to better understand their characteristics.
Natural
It is the one in which he defends that all life that has formed on Earth is random and normal. In addition, the cause of it is the rocks that have collided on the earth's surface that had living organisms. Planet Earth is in the "habitable zone" of the solar system. Therefore, thanks to the environmental conditions, it can hold water and a stable temperature.
In addition, the layers of the atmosphere they protect us from the sun's harmful radiation. It is thanks to this that life on the planet has been able to develop.
directed
This type of theory is more for those more daring and conspiratorial people. Conspiracy is something that abounds greatly in the theories of the millions of people who inhabit the Earth. It's about thinking about what everything that happened with evolution and human life has a reason. That is, the process by which a meteorite or comet impacted the Earth with microorganisms capable of developing human life is directed by someone.
In this sense, we can say that directed Panspermia is one in which life on Earth was forced by someone and it was not a random process. This theory is divided into those people who think that this was done to create organisms on Earth with life and those who think that our planet can go abroad to continue doing what is necessary in other worlds of other distant stars.
Questions
It is something crazy to think that the origin of life on the planet was something directed. With what purpose? That is, in the case where there was intelligent life on other very distant planets, why would they precisely send organisms to live so far away? Is it possible that planet Earth is the only habitable planet in a large area and that is why they had to resort to it?
There are many questions that give rise to this type of theories. And it is that the origin of life is something that, no matter how much scientists study, we can never know 100%, since "no one was there to tell about it." Like you can never know what is after death, we cannot rewind back and know the first thing there is from the beginning of time.
One of the facts that make this theory think as true is the existence of organisms that are capable of surviving in outer space. That is, they are microorganisms that are not affected by the lack of gravity or oxygen to live. Some think that many of the space objects like Voyager mission are made for humans to spread the "seed" to other places in space or to communicate with those who sent us here.
Detractors and defenders
For this theory there are both defenders and detractors. The latter are those who think that living organisms cannot survive the impact of a meteorite on Earth. First, when coming into contact with the atmosphere, the extreme change in temperature means that no organism that we know of on our planet could survive it.
Therefore, following the steps of this theory, to live on Earth you would have to meet terrestrial conditions, so it could not survive an impact of such dimensions.
Whatever it is, Panspermia is another of the many theories that exist about the development of life on planet Earth. And you, do you know another theory?
