For years, scientists have theorized about what aliens might look like.
But researchers now assert that extraterrestrial beings may even have evolved in a similar way to creatures here on Earth.
What do aliens look like?
Theory of Oxford University
A 2017 study from the University of Oxford suggested that the process of natural selection that produced the species we see here on Earth likely took place on other planets as well.
Natural selection is a process outlined by Charles Darwin, which suggests that the species best suited to their environment are most likely to survive to pass on their genes.
On Earth, this has led to human evolution over billions of years.
But in another world, scientists believe life could look completely different depending on the conditions on the planet.
Sam Levin, a researcher at Oxford’s Department of Zoology, said: “We still can’t say whether aliens will walk on two legs or have big green eyes. But we believe the theory evolution provides a unique additional tool for trying to understand what aliens will be, and we’ve shown some examples of the kinds of powerful predictions we can make with it.
“There are potentially hundreds of thousands of habitable planets in our galaxy alone. We can’t say if we’re alone on Earth, but we’ve taken a small step forward. to answer the question, if we weren’t alone, what’s our neighbor like.”
He refers to events known as “the great transition” – which have driven the evolution of different species.
It occurs when single-celled organisms evolve to become organisms made up of several cells.
Scientists believe this eventually led to the rise of humanity as it is today.
Levin added: “By predicting that aliens have undergone a major transition – that is, the level of complexity that has arisen in species on earth, we can say that there is a degree predictable to evolution that would make them look like us”
Theory of Arik Kershenbaum
Meanwhile, zoologist Arik Kershenbaum used his knowledge of the evolution of animals in the wild to determine what aliens might look like.
“If you follow things far enough, there’s a connection between any two individuals from any species,” he told me. The Age of Israel.
Written as part of his book – ‘A Zoologist’s Guide to the Galaxy: What Animals on Earth Reveal About Aliens and Ourselves’ – he studied how Some animals adapt to situations over a period of time.
“If the problems animals face on Earth are similar to those faced by other planets, and without the multitude of solutions to specific problems like getting energy from the sun and stars, stars, planets will tend to develop similar solutions to similar problems on different planets. ”
