However, the reality is that the use of eponyms in the naming of species poses a wider, more problematic nature. Traditionally, eponyms typically reflect benefactors, academics and officials affiliated with the individual who discovered a species – which is a practice that continues today. With science of the 19th and 20th century largely dominated by white men from colonising European nations, this meant many of those honoured are strongly associated with the negative legacy of imperialism, racism and slavery.
Another striking example of the dangers of overtly politicizing biological names is Anophthalmus hitleri, a cave beetle named after Adolf Hitler in 1933 that is currently threatened due to high demand from collectors of Nazi memorabilia. Due to codes around renaming species, whereby the first name given to a species is deemed its correct one known as the “Principle of Priority”, proposals to rename this species were rejected.
In a recent commentary published in Nature Ecology & Evolution researchers from various global Universities assessed the scientific names of all African vertebrates currently listed on the IUCN Red List. This revealed that 1,565 species of bird, reptiles, amphibians and mammals - around 24% of their sample – were eponyms, notably of white, male Europeans from the 19th and 20th centuries.
The authors argue that it is time to rethink the use of eponyms, and emphasise that whilst there currently isn’t a standard for changing species names, with technical and administrative barriers to doing so, renaming eponyms to better connect with local geography and culture could provide wonderful opportunities to highlight the importance of biodiversity conservation and to reinforce the deep links between nature and local societies.
