You can take a flatworm, cut it in half, subject it to an electric field so it grows two heads. Later, without the external field, you can cut it in half and both halfs will grow a second head. It's not genetic expression, but the electric field of the flatworm that has changed permanently and is directing cell growth. So if your entire body has its own field, that retains its uniqueness, and can even cause cell specialization what then? https://www.newscientist.com/article/2132148-bioelectric-tweak-makes-flatworms-grow-a-head-instead-of-a-tail/ https://www.newscientist.com/article/2132148-bioelectric-twe... “A totally normal-looking worm with a normal gene expression and stem cell distribution can in fact be harbouring a [body plan] that’s quite different,” says Levin. “That information is stored in a bioelectric pattern – it’s not in the distribution of tissues or stem cells, it’s electrical.”
