This article shows a newly-discovered defense mechanism, adding methionine in a random fashion to newly produced proteins, confusing the invaders:

David, -Going deeper into the article, it talks a little more about epigenetics as a whole--and this underlines a point I've tried and failed to make in the past: epigenetics is a mechanism for change, but that change only gets transferred to future generations in one way. How does epigenetics then "prove" Darwin wrong? (Science isn't about "proving," i hate that word in any non-math context.) -Classical theory simply states that genetic changes are passed to offspring in one way... epigenetics would provide an elegant solution to the perceived speed problem. Perceived because I haven't actually seen a substantial argument to dictate what the "speed" of evolution *should* be. And before you (or anyone else) jumps on me about calculated mutation rates, I will remind that those are always specific to a particular species, thus, there's enough mathematical variation that we cannot infer back to the beginning of life.

\"It is, brahmin, because of attachment to views, adherence to views, fixation on views, addiction to views, obsession with views, holding firmly to views that ascetics fight with ascetics.\"
