On Having a World View LIFS 691 Advanced Evolution
My Dissertation Advisor Arthur E. Dunham, Ph.D.
Think deeply about your world view. • A good world view enables one to achieve a greater understanding with less work. • Ineffective world views are ultimately replaced by more effective ones (in the sense of a scientific revolution, but the process is not necessarily that dramatic). • If you cannot identify factors that have influenced your world view, you probably do not have one.

My World View 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.
My World View 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.
My World View 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.
