In the article, they mention that two different species of electric fish evolved independently, by two separate genetic pathways. For a long time I believed that if two organisms were phenotypically similar, they must have a nearby common ancestor. But I keep reading more and more about how nature seems to stumble across the same adaptations and mechanisms via many different routes. E.g. what we know as a "tree" is not a distinct phylogenetic branch, but a form that has evolved independently over and over again [1] [1] https://eukaryotewritesblog.com/2021/05/02/theres-no-such-thing-as-a-tree/ https://eukaryotewritesblog.com/2021/05/02/theres-no-such-th...
