ITT: Tardigrade related

So I would like to introduce the tardigrade.

> can survive temperatures from slightly above absolute zero to higher than boiling point of water
> highly resistant to radiation and other toxic entities
> withstands pressures WAYYY more than the Mariana trench
> can go without food for 10 years
These next few combined may provoke conspiracy theories
> can survive the vacuum of space for a long ass time
> apparently ONLY 1/6 of their genome is shared with other discovered organisms
> the rest is completely foreign
> biologists have no fucking clue how they came to be in that case
Can /an/ theorize where these resilient fuckers came from? So far their origin is a fucking mystery. Pic related

Tardigrades are the supreme beings i the universe.
They come from beyond our galaxy, and in all other corners of the universe, they are the masters of all.

Do we really need to shitpost on /an/ of all places?
I mean come on, this is such a slow board, why shit it up?

> apparently ONLY 1/6 of their genome is shared with other discovered organisms
Absolute bullcrap. Even standard genetic markers like COI work on them: https://www.ncbi.nlm.nih.gov/nuccore/?term=tardigrada+co1

And here are some full genomes to download, in case you want to check manually.

> biologists have no fucking clue how they came to be in that case
They are Ecdysozoa ("animals that molt"), which includes arthropods, nematodes and some others. They are closely related to arthropods (crustaceans, insects, chelicerata, myriapods). Their closest living relatives are the velvet worms though, which are also close to arthropods. All of this is well known and researched and backed both by morphology and genes.

Oh also all their resistance only concerns the dormant state they can enter when their habitat dries out. They don't actually live in any of these conditions so they're not extremophiles but their dormant state can endure them for some time.
