If there is a genetic mutation in an individual strong enough to modify there chance of survival it opens the door for natural selection. If the effect is positive they are more likely to outlive their original species. If it is negative it decreases their chance of outliving their original species. Also known as survival of the fittest it favors positive trays by "eliminating" negative ones.
Only natural selection could be the answer here as natural selection is the main driver of adaptive change leading to evolutionary change and speciation in large populations.
Natural selection is only the result of changing environments, mutation and the variation resulting therein. Natural selection is the process of adaptive change and the main mechanism of evolution that leads to speciation. Natural selection is a process as mutation and variation are grist to the mill of natural selection.
Natural selection explains adaptive change in the immediate environment.
- natural selection - sexual selection - genetic drift - immigration/emagration
Adaptation does not allow for natural selection: natural selection causes adaptation.

Genetic change is necessary for natural selection to take place
Natural selection usually causes a species to change gradually

Natural selection works best on traits that enhance an organism's fitness, which is its ability to survive and reproduce in a specific environment. These advantageous traits increase the likelihood of passing on genes to the next generation. Additionally, natural selection is most effective in populations with genetic variation, as this variation provides the raw material for adaptive changes over time. Environments that change frequently or are highly competitive also tend to drive natural selection more strongly.

Yes. Without natural selection there might probably still be change, but it would produce a fine gradient of diverging morphologies in every 'direction' of change. Natural selection limits the 'directions' of change, thereby producing distinct morphologies and thus distinct species.
If a population exists in an environment that changes very little, then natural selection may not provide any pressure to change. However, even under these conditions genetic driftoccurs, introducing random change within the parameters set by natural selection.
