Since Charles Darwin formulated his theory of natural selection, our view of the world has changed. Although Darwin’s theory itself has "evolved," scientists agree that living species slowly but surely diverged from common ancestors. This program begins with a segment on fossils, one of the most convincing proofs of evolution. It then retraces the major steps of evolution as they were uncovered by science. It also presents the major theories of evolution. (23 minutes)
