Editing 1147: Evolving

In a ''{{w|Pokémon}}'' game, a player goes out in search for the eponymous creatures. Many Pokémon can be found directly in the wild, but there are also a lot of Pokémon that require training and growth, to cause them to "evolve" into new Pokémon. "Evolve," the game's term, is a misnomer which [http://www.cephasministry.com/save_our_children_pokemon_booklet.html earned itself quite some controversy in the past;] in reality, Pokémon "evolution" is more akin to puberty or metamorphosis, since instead of the entire species of Pokémon acquiring changes through an extended period of time, one specific member of the species grows instantly to the "higher stage." At that point in the game, the Pokémon glows before transforming into the new form, then stops glowing, and the very same text ''"What? XXX is evolving!"'' is used (see [https://www.youtube.com/watch?v=2qUwWAMgy3E this video] or {{w|File:Pokemon evolution.png|those screenshots}} for instance). The changes of such a transformation can be [http://veekun.com/dex/pokemon/wimpod quite] [http://veekun.com/dex/pokemon/golisopod dramatic] ...

This comic depicts the "evolution" of bacteria as observed by a Biologist in the same format as the game Pokémon. Here we have ''{{w|Staphylococcus aureus}},'' which is not a desirable bacterium (it causes {{w|Staph infection}}s) which evolves into {{w|MRSA|"Methicillin-resistant ''Staphylococcus aureus''"}}. {{w|Methicillin}} is an antibiotic. If the bacterium becomes resistant, it means the antibiotic will be less effective against it, making infections harder to treat. Thus the observer is not pleased with such an evolution.

The title text references this by suggesting that biologists do ''not'' want bacteria to evolve in this way, as opposed to Pokémon where you put a Pokémon on the "front lines" as much as possible to gain it experience and hope it evolves. A point of irony is that Pokémon evolution can easily be prevented, by using an Everstone, or stopped, by pressing the B button in the game controller during evolution, especially if there are [http://veekun.com/dex/pokemon/vigoroth Pokémon that one does not want to evolve.] The bit about the front lines is that, if a bacteria colony is exposed sufficiently to an antibiotic, those bacteria with any level of resistance to the antibiotic are less likely to be killed by the antibiotic, and are able to reproduce in spite of the antibiotic. Most future generations of bacteria now have this level of resistance instead of just a small subset. This makes the likelihood of future more resistant and harder to treat mutations even more likely.

''{{w|Staphylococcus aureus}}'' is a very common bacterium, that under an electron microscope looks like the xkcd drawing, and is the major cause of staph infections in the nostrils and skin. Hospitals are often plagued with outbreaks of {{w|Methicillin-resistant Staphylococcus aureus}} (MRSA), which is very difficult to treat as the typical antibiotics do not work on it.
