I don't think the scorpion will evolve into something entirely different than what it is and has pretty much always been
But that's exactly how evolution works: keep changing until optimum output is achieved. If the input variables change (which they won't, because it lives in a desert and eats bugs), then mutations will produce a change.
The fact that "everything evolves" doesn't prove that life is simply the end result of sheer randomness
well we have a whole trail of "mutations" going from soup to monkey, so yes, we do kinda have proof that soup produces life because we can point to all the incremental changes in the fossil record
it's this process: https://en.wikipedia.org/wiki/Abiogenesis
like take an RNA virus, the mutation rates are much higher as there is not the same correction mechanisms, randomness is built in. viruses are relatively simple and we can currently create new ones by inserting new stands in their RNA and growing it inside a cell. some viruses don't actually reproduce by themselves, they infect another virus and that does the reproduction for them. So it's hard to define 'life' as something that reproduces, so you could argue that some viruses aren't really living things
Scorpions don't just live in the desert, they live literally everywhere between the tropic of cancer and the antartic circle https://upload.wikimedia.org/wikipedia/commons/a/a4/Scorpiones_distribution.png
And no, scorpions aren't going to evolve into industry and space rockets builders no matter what's the "input variable"
Q: Where are scorpions most commonly found? A: deserts
The ones in wetter climates changed colour, because evolution
And no, scorpions aren't going to evolve into industry and space rockets builders no matter what's the "input variable"
except they will evolve if the variables ever change, but right now they have a niche and every other niche is contested by better adapted creatures. That's why there is more than one animal on earth, everything came from soup and every fork adapted to its environmental niche. Hence there are more scorpions than fish in the desert...
If everything else died, then scorpions would mutate into other creatures, maybe back into Eurypterids (sea scorpions)
Everything evolves, otherwise the only life on earth would be fish, but some fish started using their fins to move onto land and the "inputs" made this an advantage, because then there were zero predators on land.
Tropical forests aren't exactly deserts, in fact it's the opposite of deserts, it's called the environment and yet this major variable isn't decisive
