Say what?

All through the ordering process, I've been staring at this book title. If you're not an evolutionary biologist, this is one that will definitely cause you to fall on your face in confusion. I'm not sure why we ordered it for our community college library.

The title is: The Deep Structure of Biology: Is Convergence Sufficiently Ubiquitous to Give a Directional Signal? edited by Simon Conway Morris.

It could be that I'm just terribly ignorant, but I suspect that this title would elicit a "huh?" and a furrowed brow in many a learned soul.
