Everything is possible in this universe even the existence of numerous cultures more or less intelligent than us. Considering the fact that there are more than 100 billion planets in our Milky Galaxy only, the possibilities are endless. At least 20% of these cosmic bodies could host life. While space agencies continue searching the skies for signs of other civilization, we can start understanding how much alien looks can differ from us.
The Study Used Darwin’s Evolutionary Theory to Understand How Alien Looks Can Evolve
Learning more about aliens seems like an impossible mission. Even though the conditions on Earth led to the evolution of limbs and eyes, it doesn’t mean that these body parts are replicated in other corners of the universe as well. The same goes for the DNA that codes everything about a being and the ubiquity of carbon in our tissues.
Therefore, researchers at the University of Oxford used Darwin’s evolutionary theory as starting point for discovering how aliens should look like. The idea of evolution indicates that an organism suffers numerous mutations throughout history with the purpose to adapt it to its surrounding environment. These natural selections are therefore influenced by the type of planet aliens live on.
“This is a useful approach because theoretical predictions will apply to aliens that are silicon-based, do not have DNA, and breathe nitrogen, for example.”
No Matter the Laws that Govern Aliens’ Planet, They Still Similar Evolutionary Stages with Humans
By looking at the evolution on Earth, scientists understood that this transformative process could be triggered only by powerful events. From this sole observation, researchers extracted numerous predictions. Most of them underline the idea that alien looks might very well resemble humans.
Some of these predictions indicate that the organisms must have created some form of hierarchy. Governed by order, they all work together to form an alien. Each organism will have its own internal mechanisms to avoid conflict, enable system maintenance, and open cooperation links.
The study intends to go further than physiology and predict the behavior of alien life. If one day humans learn they are not alone in this universe, they will have the knowledge to interact with extraterrestrial creatures.
