Kenneth Weiss on Defining Evolution

Our understanding of evolution is dynamic, approximate, and always changing. Even in a culture war, we should be on guard to keep it that way. We should not allow ourselves to respond in kind by being bullied into insisting on a too neatly packaged or simplistic, much less dogmatic view, even though expressing uncertainties about our knowledge provides food for our opponents. If our science is to remain healthy, we should always be putting ourselves on trial.
