My problem is that when we talk about the evolution of a species, we are talking about a species as though it's a thing. This strikes me as somewhat mythological: humans cannot evolve (except in a different sense intellectually perhaps), but what it means to be human is slowly shifting-- there's a kind of Archetypal Man who is changing over time, both genetically and memetically (if I can coin that term).
So what, exactly, is changing over time? Nothing, in fact, is changing, at all, ever, in evolution, any more than colors change from red to blue in a rainbow. Nothing is developed, and yet it obviously IS developed.
Populations are changing through time. So yes, there is something changing.
And your issue is apparently more to do with how species are defined, as there are numerous definitions. And even among species definitions, no one really applies them to bacteria or viruses because they evolve too quickly to even assign to species in many cases.
