"Streaming Gradient" by Jen Stark from Jen Stark on Vimeo.
Evolution is a science of connections, and connection does not stop with ties of humans to apes, apes to other animals, or animals to microbes. Life and nonlife are also connected in very fundamental ways. The organization of life is material and energetic.
Life exists in the very real thermodynamic difference between 5800 Kelvin of incoming solar radiation and 2.7 Kelvin of outer space. It is this gradient upon which life's complexity feeds. This thermodynamic idea connects life to nonlife.
Life is one of a class of systems that organize in response to a gradient.
