Musket (Ian) picks up the point explored in "Microbiology considerations for infection control" a copy of which I lent him when he was looking at the regulatory side of infection control. (I teach microbiology a a medical school at Glasgow University.)

There is an interesting chapter which looks at the sustainability of antimicrobial resistance as a result of intervention with drugs. Using fruitfly, induced resistance has shown no deterioation after two hundred generations with genetic morphing of bacteria over that period to overcome the resistance, leading to debate over whether we can call this (the morphing of certain bacteria) an example of evolution.

The trick of course is use of the word "evolution."

Thesnail has just said "no." Not sure what the "no" was to, but Musket asked a legitimate question based on recent research in my field. We are asking it too, and there are a number of papers published in BMJ, Lancet etc freely using the word "evolution" to describe phenomena observed over a two year experiment.

Musket's final question can however be answered.

Both.
