Welcome to the DragonflyIssuesInEvolution13 Wiki

Together all participants in Project Dragonfly Issues in Evolution Advanced Seminar in Fall 2013 will contribute words, definitions and explanations to a collaborative wiki. We will use this to advance our understanding of biological evolution and, if we are successful, yours.
