But how was evolution able to get to the jellyfish? The evolutionary process is pretty simple: generate a ton of random mutations and then let natural selection filter them. The overwhelming majority of mutations end up being harmful or neutral. An exceedingly small fraction are beneficial. If you could somehow give evolution a sense of embarrassment, so if every time it produced a fish with no fins or a bird with no wings, it felt a deep sense of shame and promised to be more careful next time – evolution would no longer work. It needs to be able to explore the fitness landscape with bad traits in order to produce good traits, and this exploration requires a willingness to produce unfit organisms. The only way evolution could get to the jellyfish was by being willing to produce the countless jellyfish-adjacent organisms which went extinct.
