Nomenclature does affect everyone who has a need to identify the species, which is a much larger population than just scientists interested in the subject. It’s just that most people are ignorant of just how much it affects them. As the Plecostomus anecdote illustrates.
Like my mother (in her 90s and quick to point out that she is "of course not racist, BUT…").
She just HAS to giggle every time she even catches a glimpse of one in a bowl of mixed nuts, and proclaim loudly "You know… we used to call those nigger toes! Weren’t we naughty! Of course I’d never call them that now…
Uhh, mom, you just did, in front of everyone, and have sullied every thought I ever have about them.
As a gardener, birdwatcher, and reader, I tend to reference using the taxonomical names at times. Handy when traveling in other countries where the common and popular names differ. Readers of my writing often comment on how they like the ways I use the Latin names in poetry.
Okay, another white Southerner weighing in: maybe that name is just an Arkansas thing, because I’ve never hear that flower called anything but a “black-eyed Susan”, even among the casual racists I’ve encountered in Georgia and North Carolina. I, and most of the people I know, would certainly call out anyone using that type of language. So please don’t lump all of us white Southerners in with the ignorant Arkansans who use a hateful word for a lovely flower.
Me too - I often look at wild flowers in my videos and although I do usually refer to them by one of their common names, I also put the formal name on the screen, because common names are often highly geographic and are sometimes reused for different plants elsewhere (for example ‘Black-eyed Susan/Susie’ refers to Thunbergia alata where I live.)
Learning the Latin names (some of which are actually based on Greek) actually helped me quite a lot in understanding Romance languages and trying to make myself understood when travelling (I am not fluent in Spanish or French, but if I get stuck, choosing an English cognate of a Latin word increases the chance of being understood in those languages).
Life scientists have it easy with their binomials. Minerals are uninomial. One of my favourite geochem lecturers had one named after her after she died.
Okay for everyone here-
Western lowland gorilla=Gorilla gorilla gorilla
The Mola (large weird fish aka Sunfish)= Mola Mola. (Many fish are called “sunfish”)
American Bison= Bison Bison.
Now you can sound like a specialist. - “By Gorilla, do you mean the Western lowland gorilla- Gorilla gorilla (pause) gorilla ?”
