"Reverse evolution" is simply normal evolution: mutation, selection, inheritance, in some order. It doesn't "march" in one or another direction, that's simply how we interpret it.

And, if I'm parsing the paper right, the mutation itself wasn't even reverted. It's just that additional mutations made the relevant enzyme behave more like it used to. Like twisting a wire twice, you know?

However, for now, this is just a theory

😠

So, these non-GMO fruits are not unlike the GOP?
