Except neitherhas lived in the same form for 200 million years. So no, you are wrong.
“Sturgeon are thought of as a living fossil group that has undergone relatively slow rates of anatomical change over time. But that’s simply not true,” said Daniel Rabosky, assistant professor in the U-M Department of Ecology and Evolutionary Biology and a curator of herpetology at the Museum of Zoology.
“Our study shows that sturgeon are evolving very quickly in some ways. They have evolved a huge range of body sizes. There are dwarf sturgeon the size of a bass and several other species that are nearly as big as a Volkswagen.”
Most of the fish groups fall into one of two categories. Fish like the gar form species very slowly and show little range in body size. Others, like the salmon family—which includes salmon, trout, whitefish and char—do both: they form species quickly and have a wide range of body sizes.
Sturgeon have been around more than 100 million years and today consist of 29 species worldwide, including the lake sturgeon found in the Great Lakes. They don’t fit the general pattern found by Rabosky’s team; there are few sturgeon species but a great variety in body size.
“In that sense, they’re kind of an outlier,” Rabosky said.

If the whole amoeba/bacteria thing applied surely they would revert yes?
All organisms remain that same organism. We have tried with selective breeding to make an organism change into another organism, but it doesn't happen. Selective breeding is theoretically much quicker than "natural selection", so if it actually were possible to evolve an organism into another organism, we would have observed it by now.

If you want proof evolution is real just look at humans.
I reckon if you took a Caucasian person and dropped them off in the Antarctic for a few million years they'd eventually turn into Eskimoes. Because wide round eyes you'd go snow blind and a long pointy nose would fall off from frostbite.
It's why 'races' exist. Because humans around the world have evolved to the conditions of where they and their ancestors have lived for generations.
No good having pale skin in Africa, or having dark skin in Europe.
Ok now I am done.

I think we have different definitions of evolution. I was never taught it's about mutating one species into another. I was taught it was a species mutating into a hopefully better version of it self.
Evolution is upgrading what exists, not completely replacing it.
If I lived in a environment with bad air for example, I would expect if I and my descendants lived and bred there long enough that our lungs would evolve to handle the air being impure.

Of course they are sturgeons NOW... but they have NOT been sturgeons forever. There are at least 29 DIFFERENT species of sturgeon that have evolved from whatever animal was the proto-sturgeon.
they are actually evolving remarkably quickly for a group of fishes with such a low species count.

Sturgeons have evolved.
Crocodiles evolved.
Your premise is wrong.
backwards science, and allows fantasies to emerge.

Can you please show empirical evidence of the Garden of Eden? How about the occupants you put so much faith into? No? OK, please explain and show evidence why not all species of animal were accounted for on the Ark, but are now present on Earth? Please also show empirical evidence - the type of which you are demanding from others - for your deity.
The majority of free-thinking individuals don’t believe what you do. That number will decline further over time. I’m sorry to tell you religion is dying.
Evolution is a biological based science fiction of the origin of life on earth.

Random mutations happen, some helpful some not, helpful mutations make it easier for that individual to survive and pass on that mutation, non helpful ones make it harder for that individual to pass on that mutation.
I feel like this was all explained pretty well in freshmen biology

Mutations do happen weather or not they are needed.
The environment doesn’t not trigger a mutation.
No.
Then......
Evolution happens when you must adapt to survive, both the animals you listed are at the top of the food chain in their respective environments.
What need would they have to evolve?
A mutation must make survival easier for a species for it to spread throughout that species.
You don't understand evolution or you have split personalities.

What is the difference between a mutation and evolution?
Better question:
How do we evolve?
