I kept adding new principles while simultaneously revising or even deleting long familiar principles.

The science that uses tree rings to date and study the past dynamics of insect populations.Example: analyzing ring widths of trees to determine how much rainfall fell per year long before weather records were kept.The science that uses tree rings to study factors that affect the earth's ecosystems.Over the past three years, I have been working on revising these principles and I've presented numerous talks across the U. Eventually, I settled on the principles below as being representative of those to which we actually should adhere and have been adhering.I've sought input from individuals on these revisions and to all of them I'm especially grateful. One glaring change is that you will no longer notice the inclusion of the Principle of Uniformitarianism (or Uniformity).
