What would the aliens look like? Science speaks

In science fiction, the aliens are described in two ways, either as viscous and terrifying creatures, as in the feature films of Alien, or with great similarities to the human aspect.This has been the product of the imagination of creative minds, but now, thanks to a theory introduced by a group of astrobiologists, we could know what the aspect of the aliens is.Discover how.

Scientists could know the appearance of the aliens

A new study published in the International Journal of Astrobiology has taken the theoretical approach of astrobiology, to predict that the aliens could have a appearance similar to that of the inhabitants of the Earth .

The Oxford University researchers noted that it is not possible to say what aliens look like in terms of specific features or adaptations, but Samuel Levin, lead author of the study, argues that aliens will be s subjects to the same natural selection rules as we do , and as a result they will have similar types of adaptations.

Previously, the alien appearance has been imagined according to what is observable on Earth For example, c let's say that the eye organs can evolve on other planets , because they have done it here at least 40 times and are found throughout the animal kingdom.

However , this research is based on the theory of evolution to examine whether that is true.They say that aliens are likely to undergo similar biological processes, using multiple "units," which for us are cells individual, to work together for a common goal.

Even if they do not have a human-like DNA, they should still follow similar evolutionary paths. In the process, they will go through «bottlenecks », As we did.

What would the aliens look like? Science speaks

Events known as important transitions have increased the complexity of species on Earth.When these events occur, separate organisms evolve in a higher-level organism, such as cells that form multicellular organisms.And it seems that these rules apply anywhere.

Levin reasons that according to the theory of evolution, aliens will be subject to the same biological rules and therefore, will have structures similar to life on Earth .

Scientists are very excited about the possibility of finding life on other planets , for example, as the suggestion that there is extraterrestrial life in our own solar system on Saturn's moon, called Enceladus, because with the opportunity to analyze other life forms, more possibilities of understanding the origin and meaning of the life itself.

What do you think? Can you imagine what the aliens look like?

The Hynek scale to assess UFO sightings

Are you skeptical? The American astrologer and ufologist Josef Allen Hynek, creator of the Hynek scale to identify the types of UFO sightings (unidentified flying objects), was also at first. It is that the unknown, the more extraordinary and supernatural is presented, the tendency will be to seek a more or less logical explanation to, perhaps, reassure.Led by the same, Hynek came to reason at close encounters with beings from other worlds as "a matter of postwar nerves ” . Later with his own experience, he would not only rectify his initial position by stating that it is a “ real phenomenon to face ” , but it would create a classification system that you will know next.The ufologists have adopted it universally! The Hynek scale, the UFO sighting classification system Imagine that you are observing the night sky, when suddenly something in the distance, between clouds, it flashes like nothing else you've ever witnessed.Suppose you're not skeptical as Hynek was or...

Discovered possible indications of the existence of Atlantis

The existence of Atlantis has not yet been proven, however, we have some other testimony described in texts of Platon and in the well-known dialogues of Timeo and Critias .But, is there concrete evidence on the existence or not of this lost continent?

They had great natural resources , of a varied fauna where elephants were not lacking, for example, there is also a mountain surrounded by water, a very distinguished acropolis with a royal palace and a temple in honor of Poseidon , that god who protected them for a long time.
