Here's the full series, presented for your one-stop-shopping viewing pleasure. The strips do not, I think, assume any expert biological knowledge, so you don't need to be a parasitologist to enjoy them. However, a dorky and juvenile sense of humor will help a lot. Alternatively, you can read them on the Darwin Eats Cake website, where they look a little better, I think. The series starts at http://www.darwineatscake.com/?id=101.
At this point, Darwin Eats Cake will return to its regular programming schedule, with twice-a-week updates, usually on Mondays and Thursdays, except for those days that have been recognized as official holidays by the Darwin Eats Cake Council of Freeholders and its chairwoman, the duly elected Queen of Naboo.
So, stop by on Monday for a new strip, or any time to trawl the archive: http://www.darwineatscake.com.
