It's also wrong if you're considering the number of generations available for evolutionary selection pressure. But it's less wrong than what it's rebutting, so

It's also wrong if you're considering the number of generations available for evolutionary selection pressure. But it's less wrong than what it's rebutting, so I'm happy to say it's rhetorically correct. (It'd need to be a bit more precise to be pedagogically correct, à la lies to children, in my book, because it is still misleading.)
