Readers, sharpen your pencils and put on your secret decoder rings. We need you to crack these cryptograms!
First is a list of Archaea – prokaryotes that were considered "oddball bacteria" before Carl Woese and others showed that they are actually more closely related to us than to bacteria. Below that is a list of truly oddball bacteria – those that thrive in extreme environments.
Each list was encrypted separately, so each list has its own coding scheme. The answer key will be posted on Monday.
And here is, as promised, the answer key (PDF).
