In his new book “The Runes of Evolution,” Professor Conway Morris makes the argument for human-like aliens. According to the professor, there is little chance that the aliens we find in the Earth-like planets astronomers are looking at will be the green men we often see in Hollywood movies.
His argument is based on the theory that life on other planets may well follow a theory known as convergent evolution. This suggests that different species will independently evolve similar traits and features to solve particular problems presented to them by the environment. So, if the planets are similar to Earth, intelligent life that might have developed there will resemble those on Earth.
Professor Conway Morris is best known for his study of the Cambrian explosion that saw a sudden burst of evolution of complex animal life around 542 million years ago. According to him, convergent evolution has governed every aspect of the development of life on Earth.
He said it was surprising there had not been any signs of intelligent alien life yet in the many Earth-like planets astronomers have discovered so far.
Interesting, right? The idea of green-skinned, bulging eyed aliens lurking out there somewhere still is intriguing nonetheless.
