Of course they have words. What else would a tail slap on the water mean than danger?
Why do you want to call all communication signals words? This is where the ambiguity is introduced. For increased clarity we need increased granularity in language, that is, distinct concepts get distinct terms. What you are doing is the opposite here - conflating distinct concepts by giving them the same name, which facilitates equivocation and loss of fidelity in communication (how close the message received is to the one intended).
A bee dancing to the NE is telling the hive through representation the direction to food. A slime mold leaves a chemical trail to communicate that it has been here before and is a dead end. I'm sure we'll find nature has countless different ways for species to form words just as humans can create complex meaning with nothing more than a glance.
Words as abstract symbols with learned, arbitrary definitions are distinct from other kinds of signals. The former require consciousness.
They've already made it clear that species are continually "Evolving" but every species is the same as the preceding.
I think that you're referring to the claim that no member of any species naturally gave birth to a member of another species.
They call it a "paradox" that things change even though nothing changes.
The paradox is that it seems that since once there were no human beings and now there are, there must have been a beginning to humanity, yet no first human can be defined or identified.
They shoullda kept this "theory" under wraps until they perfected at least the language and definitions.
They're working on a beaver tail slap version.
Or mebbe they could just admit that individuals comprise species and even individuals change. Then start looking for how this affects the "species".
Did you mean that species comprise individuals (that's a hard word to use properly)? The change in individuals is not biological evolution unless it is change in the DNA of a germ cell that will someday fertilize another germ cell and become part of the population's gene pool.
Instead of studying change in species they have reduced the irreducible, put the cart before the horse, and ignored everything that is fundamental to change in life.
Another warning? I see a few a day these days. Somebody on another thread was referring to not throwing out the baby with the bath water when leaving religion, as if something of value were being left behind without any attempt to characterize what that is, what its value is, and what the cost of not heeding the warning might be. Then I hear about empiricism being a myopic perspective that misses so much truth, but when asked where's the beef, we get a vegan nothing burger. We hear of evolution being in crisis, but nothing close toa crisis can be identified. And you depict science as wrong-minded and on the wrong track, needing to be rethought from the ground up, but don't point to any specific problem, say why it's a problem, offer any solution, or show why it's a solution. Just warnings that the sky is falling.
