I’m on Tamerlane’s side here. Changing the names won’t make anything significantly easier and will cause huge headaches everywhere. Really, there are hundreds and hundreds and hundreds of different things to memorize in biology and medicine and names are a very minor part of it. Even just looking at name, within a field, a few Latin terms are repeated over and over. Many of the others are easily derived from common English words. Take for instance the muscles of the forearm
flexor digitorum superficialis (superficial flexor of the fingers)
extensor pollicis longus (long thumb extensor)
flexor carpi radialis (radial wrist flexor)
suppinator (supination muscle, rotating the forearm onto its “back”)
pronator teres (round pronation muscle)
The names are easy to learn, compared to their origins, insertions, courses, functions, innervations, and blood supply. The same is true throughout most of the body, and true of all anatomy and physiology. The names are the easy part, and if you are getting discouraged there, there is still a long road ahead that is a lot harder.
The same is true of taxonomy. It means very little besides historical interest what the actual species name means. I know what Drosophila melanogaster means (Dew-loving pigmented abdomen), but I don’t know what Danio rerio (zebrafish) or Xenopus laevis (African clawed frog) means, even though I know a lot about their genetics. It is a formalism, and it is much harder to learn their distributions, their lifecycles, their cladistics, their genetic manipulations, their uses, etc. The name is just the tip of the iceberg, and if that is the barrier, then you should be embarking in science, as most of it depends on detailed observation and classification.
Even where we have English names in medicine, we still have problems. How am I supposed to remember that Waardenburg Syndrome is associated with sensineural hearing loss and pigmentation deficits? What other name could I give a disease like this that conveys its symptoms, its distribution, the genes that are mutated, the treatments, and associated other diseases? Names are a minor point.
It would be akin to changing the organization of an entire library from subject to book title. It makes some sense – many people are looking for a specific title when they go into a library – but it would obviously be a huge headache with a huge downside to it.
