Wanted - examples of "everyday" evolution

A colleague is working on an article on examples of rapid evolution in the context of our "everyday" lives (i.e., things people see/encounter frequently).  What is needed are good examples, with citations, of recent rapid evolution.

Some candidate examples include

• Artemisinin resistance in malaria: see http://www.nejm.org/doi/full/10.1056/NEJMoa0808859
• Flu evolution and pandemics - many examples from swine flu, etc. 
• MRSA evolution - many papers. See for example Evolution of MRSA During Hospital Transmission and Intercontinental Spread. Science, 327 (5964), 469-474 
• PCB resistance in fish
• See this recent Economist article. 
• Also see Hudson River Fish Evolves to Live With PCBs - NYTimes.com

Obviously, many will be of "resistance" evolution (e.g., antibiotics, toxins) or host-pathogen interactions in some way.  Other examples of these would be great.  But even better would be some other recent examples of things like the peppered moth story.  Thanks
