but they don't even pose any threat to those who are vaccinated
Not entirely correct
Vaccination lowers the risk but does not eliminate it
Besides those who get sick do put a cost on the health system which could have been avoided
but they don't even pose any threat to those who are vaccinated
Speciation is a name for a pattern in the consequences of evolutionary processes, that happens to be relevant to human taxonomy.The origin of species is speciation (how new species develop), and I agree, speciation is central to evolution (as I have been arguing all along).
No, that was you trying to change the subject.But you seem to be conflating "origin of species" with "origin of life" (which is what I actually wrote).
I've already said that adaptation is an evolutionary process. If you've quit having a cow over using the proper term, great.
I do not share your difficulties with terminology. You go right ahead and use "adaptation" any way you want.Yet you just said: "Again: you are posting this in a thread about antibiotic resistance - a feature that emerges among populations of organisms sometimes quite difficult to classify into "species", and among which "speciation" is therefore a troublesome and sometimes misleading concept."
Since evolution includes speciation, it is an overly broad and inaccurate term for the specific mechanism at play in bacteria resistance to antibiotics.
Speciation is a name for a pattern in the consequences of evolutionary processes, that happens to be relevant to human taxonomy.
Antibiotic resistance is another consequence of Darwinian evolutionary processes - its relevance to human taxonomy is still being discussed, and is an interesting question if you care about taxonomy, but however the taxonomic issues are resolved the origin of antibiotic resistance in Darwinian processes will remain.

If you want to use "speciation" to describe the Darwinian evolution of antibiotic resistance in various small organisms, you have an argument with the taxonomists, not me. I don't care whether these newly capable organisms are technically new species or not.
1) Speciation is one consequence, among many, of evolutionary processes - it is among the many things explained by Darwinian Evolution, one of the broadest and and most widely applicable scientific theories we have.
2) There are several specific mechanisms involved in the evolution of antibiotic resistance. There are even some examples of adaptation, as knowledgable people use the term in discussing evolutionary processes - Baldwin effects, repurposing of prior capabilities, etc - being involved, at times. Darwinian evolutionary theory covers them all, as far as I know - it is a very useful theory.
More than that, you have attempted to deny that it could be.I never described anything about bacteria resistance to antibiotics as speciation, - - -
