Occasionally we need to learn content that involves a lecture-style delivery with students taking lots of notes.  Today was one of those days.  The PowerPoint includes content as well as links to the videos we watched.  Briefly, students were introduced to Linnaeus, Lamarck, and Darwin for some background information on how our understanding of evolution has changed over time.  We then transitioned into learning about concepts that help explain how the DNA available to an organism can change over time, and how changes in DNA can be used as a tool to track the relationships between species.  The videos embedded in the PowerPoint are also provided below:
