The more I learn about
CRISPR, the genome-editing system we've fairly recently discovered, the more it seems amazing, and also terrifying to have it present in actual living systems in the wild. You can't go fiddling around with DNA like that and hope for it not to go wrong! But clearly this sort of thing has been going on for a very, very long time.
It's like a crazy real-life version of
Core War, only we're coming in after grillions of iterations for systems that can actually survive in such an environment.
(I would like to write up what CRISPR is, what it does for real, what we currently use it for, and what we might soon be able to do - mainly because my grasp of it isn't as solid as I'd like and writing it would help. But because of that it wouldn't be a short job, and this margin of my time is way too small to contain it.)
