Natural selection is the primary process by which evolution proceeds; over long time scales, this process occurs most strongly at the level of the individual (or below). Macroevolution is merely microevolution over a long period of time.
A proximate cause must be known before an ultimate cause can be identified because proximate (behavioral, physiological, or developmental) processes determine the costs and benefits of phenotypes.
A general theory can explain phenomena in the majority of cases. Such theories are bound to be complex because ecological and evolutionary phenomena stem from multiple causes.
