Biology PhD weighing in here - the shirt is great!
Oh, and about evolution. It may be named a scientific theory, but it is a testable process, proven thousands of times in experimental lab groups on C. elegans, bacteria, viruses, D. melanogaster, and even mammals (mice, rats, etc). See Dan Hartl, Richard Lewentin, Christopher Marx and many many others for citations.
Evolution: (very slow) change we can believe in!
