Dolphins, like all other life, are entirely formed by natural selection. There's not a single part of them that hasn't been touched, over the course of their evolutionary history, reaching back to the first cellular lifeforms, by natural selection: from their overall shape and colour to the metabolic pathways in their cells.
One of the most apparent adaptations of dolphins, relative to other (land-dwelling) mammals, but not unique to dolphins alone, is the adaptation of their morphology and physiology to a completely aquatic existence.
Adaptation does not allow for natural selection: natural selection causes adaptation.
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
They are the selective agent in natural selection ;)
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.
no, inherited traits are responsible for natural selection

Adaptation does not allow for natural selection: natural selection causes adaptation.
The prefix of natural selection is "natural" and the suffix is "-tion".

That selection was natural.
Natural selection is what causes adaptation.
No, natural selection is the mechanism that drivesevolution.
