I love stuff like this
"You can even remove a single, special cell from an adult planarian (not an infant cell, but a cell taken from a mature adult), and from that
one cell, scientists discovered a few years ago, the worm can regenerate a whole new creature — the skin, guts, nerves, muscle, eyes, mouth, everything. It will be genetically identical to the donor."
Just completely obliterates so much of what we currently accept as true in study of biology.
Just shows how little we currently understand.
