Despite pop culture stereotypes, aliens will probably look like us
Cambridge University evolution expert Simon Conway Morris says aliens would look a lot like us, probably. Despite the popular depiction of a little guy with a big head and dewy green skin, life on planets similar to Earth would evolve very much like the species on our planet.
In his new book The Runes of Evolution, Conway Morris discusses of convergent evolution - the idea that different species will independently evolve similar features. While this might make for rather disappointing sci-fi characters, it sure makes 'Alien' an easy costume for next Halloween.
