How does evolution relate t0 drug (antibiotic) resistance?

***This chart shows the drug resistance in three different types of diseases over time; MRSA, VRE, and FQRP. Notice how MRSA has developed drug resistance the longest compared to the other two.
Drug and/or antibiotic resistance is when sub-populations of a microorganism, usually a bacterial species, can survive after the encountering of one or more antibiotics or the antibiotic does not effect the disease in any way.
Evolution relates to drug resistance because like everything else, it takes time to succeed at something. So evolution is the "time" span in which the disease can become drug resistant.
MRSA carries several drug resistant genes, another name used for MRSA is "superbug". This means it carries pathogens resistant to multiple antibiotics. From the 1950's, there has been an increase in the frequency of antibiotic resistance in bacteria. Also with respiratory illnesses, skin disorders, and sexually transmitted diseases.
MRSA is mainly a type of bacteria and in someway it is able to change itself (as an adaptation to survive), when this happens it then can refuse or resist the antibiotic trying to kill it off. So over time or as it evolves, the resistant MRSA replicates and is now considered drug resistant.
Unfortunately this can happen with many other life-threatening diseases, evolution plays a large role in relation to drug (antibiotic) resistance.
