As a companion to its NOVA Odyssey of Life series, PBS has created a fascinating web site that is highlighted by a morphing embryos section that allows the viewer (with the proper software) to see the development of fish, chicken, pig, and human embryos. Also at the site are a virtual tour of the microscopic animals that live on you, your furniture, clothes, and books; an interview with Lennart Nilsson, the famous endoscope photographer; a cyberdebate between a creationist and an evolutionist; and a teacher's guide for both parts of the series (under Learn).
