Human ingenuity never ceases! This wonderful website from the Cold Spring Harbor Laboratory tells the story of how a common Mexican weed (teosinte) was slowly manipulated by humans until it transformed into corn. As an introduction, users might want to start by watching a 2 minute and 50 second video of maize plants growing at Cold Spring Harbor Laboratory. After that, it's a good idea to look over the six separate sections here, which include Domestication, Hybrid Vigor, Genome Sequencing, and Jumping Genes. Each area contains explanatory text, photos, primary documents, and thoughtful explanations of complex scientific ideas.
