We associate light with the radiant beams that make the world visible to us. But the visible spectrum is only a tiny percentage of an electromagnetic spectrum that extends unimaginably far in both directions. And, as biologist Michael Denton carefully documents, that tiny band of visual light is crucial to life on Earth.

In Children of Light, Denton elucidates the miraculous convergence of properties on the tiny band we call the visible spectrum that has allowed intelligent life to flourish on Earth. Follow the journey of light as it beams down from our Sun, through the protective blanket of our atmosphere, to the Earth. Once here, it powers photosynthesis and unlocks the oxygen needed for life. It allows the high-acuity vision that led us to civilization and technology. Light is just one more part of the epic story of our fine-tuned universe, fit for us to flourish here and come to understand it.
