Evolution in Action
Interactive feature showing how random mutations can lead to species-wide change.
Evolution 101: Genetic Variation
Introduction to the basic mechanisms of evolutionary change: mutations, gene flow, genetic shuffling, and development.
Science Explained: Genetic Variation
Offers an introduction to the three categories of mutations genome, chromosomal, and gene as well as mutation mechanisms and types.
Mutation, DNA Repair, and Recombination
Looks at changes in the information stored in the genetic material, how they occur, and what the consequences of such changes are, and strategies cells use to minimize DNA changes and damage.
Examines the difficulties in studying mutation, the ultimate source of all genetic variation.
