I would like to recommend this paper for the Good Paper Journal Club:

Decaestecker E, Gaba S, Raeymaekers JA, Stoks R, Van Kerckhoven L, Ebert D, De Meester L. Host-parasite ‘Red Queen’ dynamics archived in pond sediment. Nature 2007 doi:10.1038/nature06291.

The paper is one of 15 evolutionary gems highlighted by Nature to celebrate Darwin’s 200th birhday on February 12. The paper is nicely summarized as 8 A case of co-evolution.

Every paper with a literary figure in the title deserves mentioning. The Red Queen is a fictional character from Lewis Carroll’s fantasy novella Through the Looking-Glass and looks like this:

And the pond mentioned in the title (‘Abdij van ‘t Park’, Heverlee, Belgium) is here:

The Red Queen Hypothesis states that For an evolutionary system, continuing development is needed just in order to maintain its fitness relative to the systems it is co-evolving with. I mainly like the paper because it is an elegant experimental proof of this important hypothesis. And the title is a perfect summary of the paper.
