The process by which sequences of four simple chemicals – adenine, thymine, cytosine, and guanine – shape a molecule of DNA and, ultimately, all the organisms that comprise the Earth’s biota, is an extraordinary story. It is a story about the foundations of biological diversity because the entire tree of life is rooted in genetic diversity. It can be a rather complex story, and if your recollection of Hardy–Weinberg equilibrium, phenotypes versus genotypes, alleles, diploidy, and so on has rusted a bit, you might find it helpful to review the genetics and evolution sections of an introductory biology textbook before proceeding.
