Pacman Memes

The most accurate depiction of endosymbiotic theory I've ever seen. Nature really said "oops, I accidentally ate this bacterium... might as well do it again to make it look intentional." First a primitive cell swallows an alpha-proteobacterium and—surprise!—gets mitochondria as a participation prize. Then, not wanting to look like a one-hit wonder, it gulps down a cyanobacterium and boom: chloroplasts! Two billion years of evolution explained by the same logic we use when accidentally liking someone's Instagram post from 2014 and then liking two more to make it seem deliberate. Cellular evolution: the original "fake it till you make it" strategy.
