Apparently Planaria (a kind of worm)can re-create itself in it's genetic entirety either from the head or body after de-capitation, and AMAZINGLY from a single cell. WOW.
On top of that, the new Planaria retains memories...
Does this change everything? Probably not immediately, but, holy crap, maybe that 95% of "junk" DNA in us humans, maybe just maybe, this ability could be discovered in us?
Not that the planet needs a few more of me.
Fascinating nonetheless.

This is so odd. I saw one like that tonight, a type of Planaria that has a
hammer looking head. The marsh is out back and so I thought of your
post...it was on the stucco on a beam of the porch in a damp area where
I have a nice holly tree. I was not sure...I though is that one of those type
of make another if you divide it type worm things? So I had some garden
scissors and I thought I will just flick it off on the porch and did not mean
to divide it, yet that is what occurred. I did a few things keeping a
watch...the part with the head went one way and the other piece laid
there and within maybe 5 minutes it grew a head! I think is there another
lesson here because you posted about them....it brought recall of the
class I had in college zoology and well...what a coincidence I thought.
Well, just thought to let you know.

That takes me back to zoology class in college where we had a day out to
a nearby creek to gather some Planaria to examine. Nice day, and a
unique experience...tucked away in my mind till you posted. Thanks!
I don't think that would occur to us as due to species and no blood. I
think I have enough trouble handling myself, one of me is enough...who
can afford it much now to exist here?

"On top of that, the new Planaria retains memories..."
Interesting that Frank Herbert was way ahead of scientific research with
Dune, considering that the sandworms, and Leto II after he became a
sandworm, had decentralized brain(s) throughout their bodies.
