I know of no government that acts, in any direct or significant way, on natural selection.
Natural selection can only act on traits that have a genetic basis, meaning they are heritable and can be passed from one generation to the next. These traits must also affect an organism's fitness, influencing its ability to survive and reproduce in its environment. Additionally, natural selection operates on phenotypic traits, which are the observable characteristics resulting from the interaction of genetics and the environment. Traits that are not expressed or that do not impact survival and reproduction are not subject to natural selection.
no there is no genetic variation for natural selection to act upon
Yes, natural selection can act upon body shape by promoting traits that enhance an organism's ability to survive and reproduce in its environment. For example, organisms with body shapes that improve their efficiency in obtaining food or avoiding predators may have higher fitness and be more likely to pass on their genes to the next generation.
This process is called natural selection. It is the mechanism by which traits that provide a survival or reproductive advantage to an organism become more common in a population over time.
Indirectly, yes it does. But it can only act on genotypes through their phenotypes.

They are the selective agent in natural selection ;)

No, natural selection is the environment! The variant organism is selected against the immediate environment where it survives and reproduces better than it's conspecifics.
yes
Natural Selection.
Natural selection explains adaptive change in the immediate environment.
Environmental factors ARE evolution by natural selection. The immediate environment is the selector of the organisms that are differentially successful against the immediate environment.

It acts on populations.
