Wasn't aware that memes were an accepted part of evolutionary biology. They're not inherited like genes through reproduction that are subject to natural selection via biological fitness. Or any other evolutionary mechanism.
There is a more recent use of ‘meme’ to refer to what we used to call an ‘internet image macro’. So the meme of the idea ‘meme’ has itself evolved to have a more specific variant of the general idea.
That's parenting and the passing of tradition. I wouldn't call it a meme. Also I can't tell if you're joking with people dying due to teeth disease.
