Bacteria don’t need to evolve to become resistant - its built in, and turns on in response to the toxin, and will also turn off later if the use is terminated.
More important is that they are not capable of resisting Alicin, nor the essential oils of quite a number of plants like oregano, camphor, and Tea Tree. But the billionairs don’t make any money off of them.
So they devolved to become resistant. Got it.
Who turns it on? How? Why? Why not turn it on from the start? Doesn't seem very intelligently designed.
