Alien life, if it exists at, all is likely to be just like us, a leading scientist has claimed. He also believes aliens would also share our human weaknesses for greed, violence and the exploitation of others, reports telegraph.co.uk.
Professor Simon Conway Morris at Cambridge University claims that extraterrestrials will most likely have evolved just like “earthlings” and so resemble us to a degree with heads, limbs and bodies.
Unfortunately, they will have also evolved our foibles and faults which could make them dangerous if they ever did visit us on Earth.
The evolutionary paleobiologist’s beliefs mean that science fiction films such as Star Wars and Star Trek could be more accurate than they ever imagined in depicting alien life.
Prof Conway Morris believes that extraterrestrial life is most likely to occur on a planet similar to our own, with organisms made from the same biochemicals. The process of evolution will even shape alien life in a similar way, he added.
“It is difficult to imagine evolution in alien planets operating in any manner other than Darwinian,” he said.
“In the end the number of options is remarkably restrictive. I don’t think an alien will be a blob. If aliens are out there they should have evolved just like us. They should have eyes and be walking on two legs.
“In short if there is any life out there then it is likely to be very similar to us.”
Extra-terrestrials might not only resemble us but have our foibles, such as greed, violence and a tendency to exploit others’ resources, claims Professor Conway Morris.
They could come in peace but also be searching for somewhere to live, and to help themselves to water, minerals and fuel he is due to tell a conference at the Royal Society, in London.
However, he also thinks that because much of the Universe is older than us they would have evolved further down the line and we should have heard from them by now. He believes it is increasingly looking like they may not be out there at all.
“It is about time they turned up,” he said. “It is very, very quiet out there. Suspiciously quiet. Where on Earth are they? I personally don’t think that there is anything out there.”
