When Charles Darwin laid out his theory of natural selection in 1859, little could he have imagined that, a good 150 years later, this cornerstone of evolutionary theory might help us form a mental picture of what alien life looks like. But that’s precisely how a group of researchers from Oxford University have done: In a research paper called “Darwin’s Aliens,” they’ve applied Darwin’s theory to alien life, positing that aliens–like humans–adapt to their environment, undergo natural selection, and move from simple to complex life forms. And, by the end, they could plausibly look something like a “colony of Ewoks from Star Wars or the Octomite” pictured above.
