That seems reasonable as long as you're consistent in applying the same skepticism to other inventions, such as the internal combustion engine and the wheel.

[Iv]

The physical principles behind combustion engines and the wheel are displayed in many life forms. Their engineering constraints and goals differ.

It is, however, reasonable to expect evolution to find a way to exploit quantum algorithms as it is very useful to several fitness advantages and is something that you would expect to be achievable through protein manipulations.

Bacterial flagella are rotary, so very close to being wheels.

Fossil fuels are primarily biological in origin. Certainly we extract the energy in a much different way, but that energy capacity is there biologically (slow burn, turns out high speeds aren't actually that useful in nature).

As for wheels, hip joints are a more efficient design of a rotatory system (multiple degrees of freedom). Wheels are much too simple a design to see much use in nature.
