Examples for jumps in evolution (as opposed to gradual changes).

Constructive neutral evolution: Are mutations directed (tangle of cables as example)? Spliceeosomal introns, split inteins (discussion section 5 this article), mRNA editing, rearrangement of gene fragments in the transistion from micro to macronucleus in some ciliates (image here), emerging interactions between proteins (here, here, and here).
