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.

pffft its still an aphid.  wake me up when one turns into a blue whale or summtin.  evilutionists

hey jean i noticed that at least some of those plants are tag-alongs with humans (clover, afalfa, peas, vetch)  i didn't recognize some of the others but i wouldn't.  

wondering if you had any idea of what the ancestral host preference mighta been?  i'm not swift enough to figure out if the biotypes that can switch hosts prefer hosts that have been strongly domesticated.  would make sense that selection for being tasty for people or livestock, if it reduces any defense complexes, might make you tastier for insects.

in one fell swoop you have generated more science than the entire ID movement in 2008 AND 2009.  Cheers!
