Jay Hosler is an Associate Professor of Biology at Juniata College and a very skilled cartoonist who writes comic-style books that are meant to entertain as well as educate. One of them, Optical Allusions, focuses (no pun) on eye evolution. I asked eye evolution researcher Todd Oakley to review it for the special issue of Evolution: Education and Outreach on eyes that I edited last year (read here), and I also reviewed it for Reports of the NCSE (coming soon). We both recommend it enthusiastically.
Now, Jay has a blog called Drawing Flies. Check it out.
