In the game Sada explicitly states when they're revealed that they were obtained through a time machine capable of capturing pokemon from a prehistoric era and bringing them to the present.
Essentially the Scarlet paradoxes (Including Scream Tail A.K.A Paradox Jigglypuff) are standalone relatives of the Pokemon we know from waaay further back in time than even Hisui.
Think of them like you would compare mega fauna of the far distant past to todays insects.
Also if it's any consolation despite not evolving all "Paradox" Pokemon have a BST of 570 except for two "Paradox Jigglypuff" is very bulky and fast.
This is just the explanation for Scarlet btw, until Violet leaks we don't know what the deal with robot Paradoxes are, might be actual robots might not.
