Caedes, not sure which question you want answered. I would have been a much better linguist than a scientist, but my father was a biology teacher and he insisted I do a BSC. My natural disposition would have been languages in which I excelled at school. But he did not want me to become a teacher, etc. And with it all came the Witness thing. My mother was a Witness.
That's one of the problems with the theory of evolution in my opinion, a lack of consensus on the definition. Yes, I know, one of the favorite excuses of evolutionists is the time factor. That's why it remains a theory. It cannot demonstrated.
I have mentioned the Coelecanth and the Horseshoe crab, millions of years old and no change. What happened there? Then there's the development of the horse as an example of evolution. Retired. And the same goes with the development of the whale. Some things are not right there either. So, no, I am not convinced. And the practical implications of an sea animal evolving and becoming a land animal. Then to reverse the process for the land animal to become a whale or dolphin. It strains all credibility.
In the case of Staph. aureus, you incubate the bacterium in a meat broth, then spray it out on a blood agar plate. You place a methicillin resistant disc on the plate. If the organism overgrows the methicillin disc, it is a problem, especially in a hospital environment. Farmers are contributing to the problem by treating their animals (cattle, sheep and chickens) with antibiotics. We are contributing to the problem by using antibiotics and releasing them in the water system through drainage. Doctors are compounding the problem by unnecessarily prescribing antibiotics (e.g., for flu which is caused by a virus). Drug companies do not want to spend millions on an antibiotic that is soon going to become worthless as the bacteria becomes more resistant. So yes, I think hospital infections of super bugs are on the increase and it is going to get worse, before it gets better.
