Expert: There must be aliens who resemble us

Published: 3:32 pm, Thursday, 2 July 2015
A leading biologist has claimed aliens resembling humans must have evolved on other planets.

Aliens resembling humans must have evolved on other planets, a leading biologist has claimed.

Evolutionary biologist Simon Conway Morris says it is surprising we have not already discovered extra-terrestrials that look like us - given the growing number of Earth-like planets now discovered by astronomers.

He based his claim on evidence that different species will independently develop similar features which means that life similar to that on Earth would also develop on equivalent planets.

The theory, known as convergence, says evolution is a predictable process which follows a rigid set of rules.

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

'One can say with reasonable confidence that the likelihood of something analogous to a human evolving is really pretty high.

'And given the number of potential planets that we now have good reason to think exist, even if the dice only come up the right way every one in 100 throws, that still leads to a very large number of intelligences scattered around, that are likely to be similar to us.'

The argument is put forward in his new book The Runes Of Evolution.

He has previously claimed that aliens would resemble earthlings with limbs, heads, and bodies.

And he goes further in the new book, claiming any Earth-like planet should also evolve predators like sharks as well as mangroves, and mushrooms, among many other things.

Could human-like aliens be commonplace ?

Some scientists believe that life is likely to develop elsewhere in much the same way as it has on Earth.
With our own planet being the only known habitable world in the universe it is difficult to predict what an intelligent extraterrestrial life form might look like, especially when taking in to account the sheer number of possible environments that must exist across the cosmos.

According to evolutionary biologist Simon Conway Morris however it seems that there is actually a pretty good chance that intelligent aliens will turn out to look rather a lot like ourselves.

"Given the number of potential planets that we now have good reason to think exist, even if the dice only come up the right way every one in 100 throws, that still leads to a very large number of intelligences scattered around, that are likely to be similar to us," he said.

His predictions are based on a theory known as convergence which suggests that evolution is a predictable process that follows a rigid set of rules no matter where it occurs.

"I would argue that in any habitable zone that doesn't boil or freeze, intelligent life is going to emerge, because intelligence is convergent," he said. "One can say with reasonable confidence that the likelihood of something analogous to a human evolving is really pretty high."

All that is possible, but it does not change that niches on an "earth like planet" will need to be filled and convergent evolution will adapt life to fill those niches. As grasses evolve and create savannahs on any given planet, life will come down from those trees and start walking.
