Presents a table showing the timeline of theories of evolution, a description of Darwin's theory of evolution, and a list of arguments attacking the concept of evolution.

The concepts of microevolution and macroevolution are explained and a two-column table that compares them is presented.

This brief explanation of punctuated equilibrium includes paragraphs on the history of the theory and the controversy surrounding it.
