Darwin Proved Right by Experiment with 'Alien' Life

According to some scientists that used a computer simulation to predict what alien life would be like. After 15,000 generations of the alien like microbial life, researchers found that alien life follows the same Darwinian rules found on Earth: Survival of the fittest. The article then continues about how Darwin had considered all species when producing his theory on evolution. Hence, hinting on how life on Earth went from microbial life about 2.2 billion years ago to galloping animals and massive plants. A researcher stated: "Our work allowed us to see how the most complex functions are built up from simpler and simpler functions. We also saw that some mutations looked like bad events when they happened, but turned out to be really important for the evolution of the population over a long period of time."
