Biology Cartoons

This page contains a selection of cartoons that were drawn by Leif Saul and used in lectures as overhead transparencies. (Some of them have not yet been used in the current semester.) Click on one of the images below to see an enlarged version of it. Explanatory text has also been added to provide a self-contained "mini-lecture" for each cartoon. The information provided here is purely to help clarify lecture material and arouse interest in biology, and its use is entirely optional.

Copyright notice: All images on this page, and the enlarged versions with text that they link to, are copyrighted 1998-1999 by Leif Saul.
