Evolution as Reproduction with Variability

In this online activity, learners discover how random variation influences biological evolution. Biological evolution is often thought of as a process by which adaptation is generated through selection.  While it is recognized that random variation underlies the process, emphasis is usually placed on selection and resulting adaptation, leaving a sense that it is selection that drives evolution.  This simulation highlights the creative role of random variation, offering a somewhat different perspective: that of evolution as open-ended exploration driven by randomness and constrained by selection, with adaptation as a dynamic, transient consequence rather than an objective.
