This is hardly a breakthrough but we've got a paper published in PNAS this week about speciation, more specifically the blurry frontier between what we may call subspecies and species. Of course, there's no strict boundary, as well as there is no qualitative difference between micro- and macroevolution, if this is relevant to the anti-evolution debate.

The work is done on an aphid species complex. Feel free to give you opinion on this. Full access requires subscription, but I can provide a pdf for those interested.
