The least mad hypothesis

Wow. Mendel's theory of inheritance thrown out the window? What if RNA contained a "backup" copy of a species' standard genome that would allow an organism to "revert" to a healthy state should both parents contain the same genetic deficiency. Inheritance theory says this is impossible. But scientists now say that is the only decent explanation for the Arabidopsis. Wouldn't this change our basic understanding of evolution?

And if human RNA contained a similar escape button? Wouldn't we need only figure out a way to press it? And then, genetic disabilities be gone? Really, I'm just asking.
