Diving

The evolution book is due in 61 days..but phyletic gradualism and parapatric speciation and cytochrome B analyses are rattling around in my brain, I need some clarity, and it's time for a break. So, off to dive. In eight hours I'll be a hundred feet down, hovering just over the sea floor in Puget Sound, illuminating the moonscape with a bright light, reathing air from a cylinder. Thank you, Jacques Cousteu and the less-well-known co-inventor of the aqualung, Emile Gagnan. The two are seen above, about to test early SCUBA devices.
