It's happened! Dung beetles have given up eating poo (at least some of them) and have turned on the millipedes that share their appetite for that which most creatures wish to leave behind. Apparently they have evolved.
Dung beetles with stronger back legs and honed heads can kill the hapless millipedes by removing their heads and eating their insides. Nasty. Scientists believe that it gives a snapshot of the evolving of one species into another.
No doubt huge amounts of creationist literature will even now be on the printing presses, showing how this proves nothing, but I thinks it's a interesting insight into the how we got here.
