The title refers to a tree that I can see from my patio, its leaves constantly moving in even a breeze so slight the other trees stand still. It is called the Quaking Aspen, and its leaves are shaped to move at the slightest stir in the breeze. They are shaped that way through evolution (Who runs evolution, if not God?) and provide a refreshing rustle on a dead hot day.
Nature has some amazing wonders, and this one perked me up on an oppressively hot day. I am enthralled by these interesting aspects of our universe.
