Evolutionary Biologist Simon Conway Morris has claimed that aliens with a strong resemblance to humans must have evolved on other planets. Morris says that species developing independently of one another will naturally develop similar characteristics as they will be shaped by living in habitable environments to evolve in a certain way.
Professor Morris even finds it surprising that we haven’t found any evidence of intelligent life yet, with the many earth-like planets we have now discovered.
Professor Morris is a leading proponent of Convergence theory – the idea that evolution must follow specific rules that therefore limit the types of beings that can evolve in a given ecosystem.
In his new book The Runes of Evolution Professor Morris says:
“I would argue that in any habitable zone that doesn’t boil or freeze, intelligent life is going to emerge, because intelligence is convergent,”
“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 theory also suggests that it stands to reason that a large number of species similar to what we have on earth would be likely to emerge, everything from sharks to spiders and mangroves to mankind.
This theory – which also explains why there are so many humans in Star Wars even though it’s set in a distant galaxy – suggests that if human like aliens ever did come to visit earth then they would potentially be able to blend in with humans without even being noticed. Allowed then to gradually assimilate with us and take over. In fact who knows? They may be doing this already. For all I know I might be the only one left and I’m just preaching to a load of body-snatching aliens who already know all of this.
