Reviewer Comments:

Sal Kahn aims to “empower everyone, everywhere with a free, world-class education” through his straightforward 10 – 15 minute tutorial videos comprised of simple graphics and personable narration. This particular collection contains four such videos which address ideas in evolution, natural selection, and intelligent design, and are suitable for a high school or college course in the biological sciences. This is excellent primary material for long distance learning, or rich supplementary material for any biology course.
