I want someone who doesn't believe in biological evolution to explain MRSA to me.

Wow! Thanks for asking! MRSA is a staph infection that tries to outpace mans ability to confront it! It's now funny that the old drugs that quit working at some point, are the most formidable against it now!

A better argument is diabetes. We have learned to help diabetes live longer by saving people with diabetes! Thereby proving the survival of the weakest!

On the contrary, the gene that makes people susceptible to type 2 diabetes when they eat too much and don’t exercise also makes people more effectively store surplus calaories as fat when food is not too plentiful and thus improve their ability to survive famine.

In societies where calaories are tight and people struggle to feed themselves, as all human societies had been over vast majority of human existence on earth, the diabetes gene, far from making its carrier the weakest, actually makes them the fittest to survive.

In societies around the world today, You can actually correlate the frequency of the diabetes gene to how recently the society had experienced very severe famines in which a large percentage of the population starved to death.   The more recent the natural selection by extreme famine, the greater the prevalence of the diabetes gene in the society it afflicted. This is natural selection visibly at work amongst humans.

More evidence of evolution taking place amongst humans even as we speak? People of Western Europeans descent have the some of the lowest prevalence of genetic susceptibility to type 2 diabetes in the world. They are the fittest to survive by your definition but would be the most at risk if a global cataclysm overtakes over global food production and distribution system.

But how comes it this way? As it turns out, careful reading of the records of people’s lives in Western Europe suggests death by type 2 diabetes and gestational diabetes were extremely common as late as the 17th and 18th centuries. The symptoms that accompanied the terminal decline of many Western European luminaries of that age are symptoms of severe diabetes. What happened?

In the 17th century, the Europeans got hold of African slaves to set up huge sugarcane plantation in the Caribbeans, and began to manufacture refined sugar on industrial scale to export back to Europe. For the first time in human history sugar became cheap and plentiful. Prior to the 17th century Western Europeans were probably just as susceptible to diabetes as most other peoples of the old world. But then came the tide of white sugar. Soon everyone who is susceptible to type 2 diabetes got it. They tend to die early and leave fewer offsprings. 2 centuries later the entire gene pool of Western Europe has been largely scrubbed of the diabetes gene.

It is fortunate during this time, rise of wealth and development meant no real large scale famine hit most of Europe outside of Ireland. For while the flood of sugar cleansed the gene pool of susceptibility to diabetes, it also deprived the society of those most resistant to famine.

Now, if a severe global famine were to afflict major societies of the world equally, people of Western European descent would be the most screwed.
