Aliens Are Real &They Look Like Humans, Biologist Claims

Aliens have been portrayed to be humanoid creatures often with green skin, bulging black eyes and elongated narrow bodies. This popular depiction may not be far from the truth, as an evolutionary biologist claims that aliens have similar appearances to humans.

Professor Simon Conway Morris, a fellow from St. John's College Cambridge, says that there should be extra-terrestrials that look like humans, based on the increasing number of Earth-like planets that are being discovered by scientists.

According to Sky News, he adds that aliens are likely to develop similar human features such as limbs, heads, and bodies and that these creatures would develop on equivalent planets.

"I would argue that in any habitable zone that doesn't boil or freeze, intelligent life is going to emerge, because intelligence is convergent," Morris said.

He explains that it is also highly likely that aliens also evolve similarly to humans.

A theory known as convergence or convergent evolution in evolutionary biology is a process where two organisms that are not closely related will evolve to develop similar traits, as a result of being exposed to similar environments or ecological niches, according to Science Daily.

"An area of biology which is becoming popular, perhaps too popular, that the possibility evolution is becoming much more predictable than people thought," Morris told The Independent. "The book is really trying to persuade the world that evolutionary convergence is completely ubiquitous. Wherever you look you see it."

He adds that the book will seek to engender the possibility that large brains, tool making, and intelligence are convergent and that it could be parallel in other Earth-like planets. He defends and claims that it is hard to imagine another evolutionary process in alien planets other than the Darwinian Theory.

His theory then leads Enrico Fermi's paradox where it tries to find the answer to the question of where aliens are and why they have not made contact with us humans. However, in the book, Morris acknowledges that he went "off-piste for a bit of fun," in the last chapter regarding the paradox, as reported by the Independent.

Not everyone is sold on the concept as they prefer scientific facts.

"I prefer to deal in scientific fact - this is wildly science fiction. You'd be off your trolley to go searching for arsenic-based life," said Professor Colin Pillinger, leader of the Beagle 2 Mars landing mission via The Telegraph. Pillinger adds that Mars is still the best planet to find out and discover more about alien life.
