The Mushroom at the End of the World: On the Possibility of Life in Capitalist Ruins

“This binomial system of naming things is kind of quaint, but it is a complete artifact,” he told me. “You define things with two words and they become an archetypal species. In fungi, we have no idea what a species is. No idea…. A species is a group of organisms that potentially can exchange genetic material, have sex. That applies to organisms that reproduce sexually. So already in plants, where out of a clone you can have change as time goes by, you have problems with species…. You move out of vertebrates to the cnidarians, corals, and worms, and the exchange of DNA, and the way groups are made, are very different from us…. You go to fungi or bacteria, and the systems are completely different—completely crazy by our standards. A long-lived clone can all of a sudden go sexual: you can have hybridization in which whole big chunks of chromosomes are brought in; you have polyploidization or duplication of chromosomes, where a completely new thing comes out; you have symbiotization, the capture of, say, a bacterium that allows you to either use the whole bacterium as part of yourself or use parts of that bacterium’s DNA for your own genome. You’ve become something entirely different.
