Single nucleotide evolution

A cool summary of a research article in PLoS Biology discusses the finding that a single point nucleotide difference in a bacterial symbiont of an aphid leads to a differential reproductive fitness in hot or cold climates. I think that I'm going to get all my bacterial symbionts sequences and make sure that they aren't responsible for my bad reaction to the tartar sauce I had with lunch.
