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
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

    "another S. aureus paper but a nice study http://www.plospathogens.org/article/info%3Adoi/10.1371/journal.ppat.1000855"

  2. Drug resistance in helminths (primarily those helminths that infect livestock and horses).

    Here is a review of the subject: Current Opinion in Infectious Diseases

  3. There is a case known in which a species of cichlids in Victoria lake in a period of 30 years diverged into a blue colored and red colored species because pollution forced adaptation of sight to specific light wavelengths. Although I can not find the specific mentioning of the "30 years" in the article, it was well covered in the news globally.

  4. Well, other than the peppered moth the only one I could think of is the emergence of lactose tolerance:

  5. I discuss stickleback evolution with my sophomore Genetics class, but fish morphology might not be all that sexy.

  6. Would tumour evolution count / be a helpful example?

  7. thanks for all the suggestions - Joe - tumor evolution is a cool idea but probably would not count in terms of an example the public might "get" as an example of evolution

  8. Another suggestion from Gina Baucom on Facebook

    This is exactly what I work on!: Herbicide resistance/tolerance evolution in the ag system http://homepages.uc.edu/~baucomra/Baucom_Lab/Publications.html

  9. How about this recent paper on evolution of P. aeruginosa during chronic infections of CF?

  10. I use the evolution of blood groups in humans as my example in class.

    Many native American populations are homozygous for the O-type allele. They clearly evolved from an ancestral population in which all three alleles (A,B,O) were segregating. This must have taken place in the past 18,000 years.

    It's a nice example because it illustrates evolution within a population, not a species.

    It's also an example of evolution by random genetic drfit, not natural selecction. This is important since, as we all know, random genetic drift is the most common mechanism of evolution. It's a good idea to teach that as early as possible.

  11. More from Facebook:

    Invasive genotype of Phragmites spreading all through North Eastern salt marshes. (And hybrid cord grasses spreading invasively throughout California.)

    Also, 'domestication' and fitness reductions in wild populations of many Pacific salmon because of hatchery supplementation.

    Fred Gould (and colleagues) work is great, especially the Bt-maize resistance evolution, and, the genetic pest management group he's been developing. Palumbi had a popular book out a while back, Evolution Explosion.

  13. Another cancer evolution example from a colleague:

  14. Another, long term 20 year plus study on microevolution and adaptation of Pseudomonas aeruginosa in CF lungs using next gen sequencing.
