365Caws is now in its 14th year of publication, and was originally intended to end after 365 days. It has sometimes been difficult for me to find new material, particularly during the winter months, but now as I enter my own twilight years, I cannot guarantee that I will be able to provide daily posts. It is my hope that along the way I may have inspired someone to a greater curiosity about the natural world. If so, I can rest, content in the knowledge that my work here has been done.

Cladonias All The Way Down
Day 22: The signature phrase, "It's turtles all the way down" has been attributed to a number of different sources (Bertrand Russell or William James among others) and was popularized by none other than Stephen Hawking in more recent times. It refers to a bit of mythology (again ascribed to various cultures) in which the Earth is described as resting on the back of a huge turtle. The expression results from a confrontation between a cosmologist following his explanation of the nature of the Universe and a member of the audience who puts forth the legend as an alternate theory. When asked what supports the first turtle, the challenger asserts, "Another turtle." The cosmologist then responds, "But what does that turtle stand on?" The reply follows the legend exactly, "Another turtle, of course. It's turtles all the way down."
In the fascinating world of lichens, nothing proves the myth more visibly than the Cladonias. On close examination, it's not hard to find proof that it's Cladonias all the way down. (Cladonia grayi)
