The world's weirdest organism just got a lot weirder:

That's amazing and peculiar. The rehydration action 'sucks' in foreign DNA/RNA and the creature will bind this inside the porous nucleus.

Do you know the way mammals get retroviruses all up in their DNA and the virus becomes part of their DNA? Is that an example of HGT? And if not, why not?

This article got me to thinking, if DNA (and the attendant genome, proteome, and so on) were prevalent in the galaxy, how would we know that a particular species was local? Presumably by it having a sufficiently different physiology and biochemistry, but how different would it need to be, to be alien?

It will only be a matter of time before creationists claim this is a chimeric organism that violates the tree of life and proves creation by god.

I've never understood how chimeras prove the existence of god. Would think it actually does the opposite with regard to belief in souls, etc. But there is no logic I suppose.

Other researchers are now questioning the finding, and saying it is just artifact:

It doesn't take much to change them from cute to scary, does it?

I think those eggs have a very uncanny resemblance to Alien pods

Perhaps the weirdest aspect of M. shonaicus, though, is its eggs. The spherical eggs are studded with miniscule, chalice-shaped protrusions, each of which is topped with a ring of delicate, noodle-like filaments. These features might help the egg attach to the surface where it is laid, Arakawa said.

The FSM will be delighted to hear about the noodly appendages too!
