Peter Warshall: Enchanted by the Sun: The CoEvolution of Light, Life, and Color on Earth

For 3.8 billion years, life has lived in a bath of solar radiance. The Sun’s illumination outlines which objects are appealing, bland, or repellant. Its powers of desiccation, blistering, bleaching, and revelation govern a balance between beauty and danger. Its flood of photons shapes light-harvesters (“eyes”), pigments, and surfaces---stretching planetary aesthetics to include "invisible light" (ultraviolet, infrared, and polarized). From euglena to Matisse, all creatures dwell in a variety of luminance locales---dramas of biospheric brightness, color mixes, and rebellions against darkness (such as fireflies and luminescent fish). The most recent rebellion has been human-devised lamps that impact everything from the artistic-military complex (camouflage and mimicry) to the materials, techniques, and display of paintings, electronic imaging, and growing plants. This 55-minute journey travels from unicells to octopi to op-art, with a dose of PR for “planetary color webs” and their influence on awareness, desire, self-direction, memory, contemplation, and curiosity. Armed with a PhD in Biological Anthropology from Harvard, Peter Warshall has shaped watershed theory and practices, conservation biology, relations with Indian tribes in the Southwest, and refugee activities in Africa. For a decade he was the editor of the Whole Earth Review.
