Great advances have been made in the field of biology in recent decades that will continue to have a major impact on our lives. Rediscovering Biology: Molecular to Global Perspectives explains these developments for teachers of high school biology to update their content knowledge and understanding. Thirteen half-hour video programs feature interviews with expert scientists involved in groundbreaking research, such as Eric Lander of the MIT Genomics Center and Rita Colwell, director of the National Science Foundation. Detailed animations provide a micro-level view of biological processes and techniques such as mass spectrometry and microarray analysis.

Homo sapiens is now the only living representative of what was once a multi-branched bush of hominid species. This session examines mitochondrial Eve and other fossil clues that increasingly point to Africa as the point of origin of our species. How ...did humans replace their hominid cousins, including Neanderthal, leaving the chimpanzee as our closest living relative?
