In a paper just lately revealed within the International Journal of Systematic and Evolutionary Microbiology, researchers within the U.Okay. and Austria have named greater than 65,000 completely different sorts of microbes. The examine, led by Professor Mark Pallen on the Quadram Institute in Norwich, attracts on an extended custom of making well-formed however arbitrary Latin names for brand new species, however applies this strategy at a scale unprecedented within the historical past of taxonomy.
Prof. Pallen argues that microbiology is a sufferer of its personal success, with tens of hundreds of new species found lately—but most stay unnamed. In the previous, micro organism have been given descriptive names or have been named after folks or locations. This strategy is presently delivering round a thousand new species names per 12 months. However, with a backlog of >50,000 nicely categorized however unnamed species, at this charge of progress, it could take at the least half a century to call all these unnamed micro organism—by which period, scientists would face the issue of naming the hundreds of thousands extra species found within the meantime.
Pallen and colleagues have adopted an environment friendly, high-throughput, big-data strategy, utilizing a pc program to generate tens of hundreds of distinctive however easy-to-use names that bear no resemblance to any present phrases. To adjust to the requirement that names for micro organism ought to be in Latin, the workforce mixed arbitrary strings of letters from the Latin alphabet with grammatically well-formed female suffixes. The result’s a set of names that recall the familiarity and gravitas of Latin, despite the fact that they lack any significant pedigree. Examples embrace Dupisella tifacia for a bacterium from the sheep intestine, Hopelia gocarosa for a bacterium residing in Swedish groundwater or Saxicetta apufaria from a Russian salt lake.
Although this may appear radical, in reality formation of names in an arbitrary trend has an extended custom, stretching again to the primary code of taxonomic nomenclature in 1869 and even again to the daddy of taxonomy, the Swedish naturalist Linnaeus. What is completely different right here is the astonishing sense of scale, with a catalog of names that runs for over ten thousand pages in what represents the biggest ever naming of species in a single publication.
Because they’ve been utilized to species found by DNA sequencing however not but grown within the lab, for now the brand new names stay provisional reasonably everlasting. However, because the code of nomenclature insists that bacteriologists purpose for stability in names and no competing naming-at-scale approaches are underway, it appears possible that the overwhelming majority of the brand new names will likely be used for years and even centuries to come back.
In closing, Pallen says “I was a member of the working group that gave us Greek letters for COVID variants, which were rapidly adopted by the scientific community. I hope that the names proposed here are also rapidly adopted and used widely. This is just the first step. The age of microbial discovery is far from over, but it will be easy to create future names en masse using the principles we have established here.”
