Space Organism Taxonomy Requires New Kingdom After Specimen Defies All Classification

The International Commission on Xenobiological Nomenclature has formally added a seventh kingdom to the taxonomic tree of life after a Martian microorganism proved impossible to classify under the existing six kingdoms or, indeed, under any existing conceptual framework. The organism, designated Specimen MJ-22, photosynthesizes like a plant, moves like an animal, reproduces like a fungus, and contains cellular structures that resemble nothing in any biology textbook published on Earth. 'It has chloroplasts, but they're on the outside,' said taxonomist Dr. Elena Russo. 'It has flagella, but they point inward. It has a cell wall made of a material we've never seen that appears to be both organic and metallic simultaneously. I've been a taxonomist for thirty years and this organism has made me question what the word organism means.' The new kingdom, formally designated Xenobiota and informally known among researchers as 'Whatever This Is,' currently contains one species. The Commission has, however, created an extensive hierarchical framework within the kingdom, including subkingdoms, phyla, classes, and orders, all of which currently contain only MJ-22. 'We wanted to be prepared,' explained Dr. Russo. 'When we find more specimens — and we will — we need infrastructure. The alternative was to keep adding footnotes to existing kingdoms, and we had already added so many footnotes that the kingdom Animalia now has a footnote longer than its original description.' The naming of the single species within Xenobiota has proven contentious. The formal proposal, 'Perplexus martiensis,' was challenged by a faction that preferred 'Impossibilis confuseum.' A compromise was reached: the organism's formal name is 'Perplexus martiensis,' but its common name is 'the thing.' MJ-22 has been observed reacting to human speech. Researchers are unsure whether this constitutes a response or a coincidence. 'It wiggled when I sneezed,' said Dr. Russo. 'I'm not prepared to call that communication. But I'm also not prepared to call it nothing.'
