There are a number of authors in what has been termed "The Golden Age of Science Fiction" that employed some aspect of their imagined view of the dynamics of alien languages where the alien words conveyed multiple and very deep meaning for concepts. Concepts we mere humans often couldn't fully understand with our limited abilities and should be in awe of rather than learn anything. Whenever I see chatter about "ancient language", beaver language and the meaning of words on here lately, I harken back to those books I read as a kid and find the similarity interesting, even telling.
I find the employment of secret, personal, alternative definitions to the well-established, widely used technical terminology of biology to be equally, interesting, frustrating and telling as well. To me it means that a person doesn't really understand the facts, concepts and conclusions they are going on about and don't offer any understanding to those reading that chatter.
If you have to invent new meaning for words, invent new, but meaningless nomenclature to describe conditions in a manner inconsistent with the facts, those beaver slaps might as well be seen as evidence for fishing by a herbivore.
Among biologists, terms like genetic bottleneck, adaptation, species and consciousness have meaning. Even where definitions are worded differently or parts weighted a little differently, communication doesn't break down. Explanations of those differences are given and argued so that understanding is conveyed. But when you have secret, alternative meanings that go further and describe conditions that don't even exist, then there is no communication. It is just an oracle repeating nonsense.
