Seems that what's really ground-breaking is not yet another study that shows similarity between species. Heck, we've known that.

What seems groundbreaking is that in a closed laboratory setting they can now actually cause the change from one species DNA to another species DNA to occur with a stop watch on the event. So now we can know definitively how long man has been on earth -- and if we can know that now with this new certainty, we're only a short way away from mapping all the genes, causing the same change to occur between each organism, time that, and we should be able to determine the exact age of biology.

Then we can double-check that against the geological record and know without any lingering doubt how everything happened.
