Preface:

The central organizing concept in biology is that life changes through evolution and that all life has a common origin. Evolution—the change in the proportions of traits or DNA sequences in a population over time—occurs every time an organism is born or dies as each of these events alters the proportion of some traits in that population. As such, evolu-tion is not a theory but an observable process. This course illustrated the processes and forces of evolution with both examples from nature as well as in-class demonstra-tions, and teachers will be encouraged to develop labs/demonstrations of their own. We adhered to the mottos “Nothing in Biology Makes Sense Except in the Light of Evolution” as well as “Nothing in Evolution Makes Sense Except in the Light of Biology.” As evolutionary biology is a highly intuitive and engaging science, teachers from many grade levels foundnthe topics applicable to their teaching.
