My reading (I am no expert) is that they are asking the question;

"If resistance is inherited (and it is) then an experiment to see how bacteria tries to evolve to overcome resistance was the point of the exercise."

"Inheritance of acquired characteristics" isn't what this is about. Our whole resistance to certain ailments goes back a long way. It isn't us changing but it does beg the question, is the annual cocktail change in the flu jab a reaction to evolution of infections and viruses?

I see this as a question, which is what I asked, of how tight a definition we can put on the word "evolve."

After all, I had a paper published once called "evolution of six sigma consideration in service improvement." Not very snappy but as in many threads here, it questions the preciousness of words by people who see words in tight definition.

A bit like "folk music" if you will...
