Biologist and author, Sean B. Carroll, who's books include "Endless Forms Most Beautiful" and "The Making of The Fittest", speaks at the Howard Hughes Medical Institute. From the institute's "Holiday Lecture" series, the 2005 video is a history of Darwinism and an overview of the evidence supporting the science of evolutionary biology. Covering Charles Darwin's "big ideas", Carroll delves into the 'the survival of the fittest, 'natural selection', and, of course, DNA. (Watch Video)

The University Of California Museum of Paleontology online is a "virtual" museum. The online exhibits include a tour of geologic time, a fossil gallery, and a special "understanding evolution" site, to name but a few. Also, there are K-12 resources for students and teachers. We recommend reading the field reports from the museum's students and faculty, and visiting the mystery fossil exhibit. It's natural history education at its best.

But along such a path the direction may change because old data may be altered and new data may be gathered. The answer is always provisional since it is dependent on future steps in the process.
