Product Description 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. This book is the third book in the Privileged Species series, which also includes The Wonder of Water and Fire-Maker.

#509 Anisogamy: The Beginning of Male and Female This week we discuss how the sperm and egg came to be, and how a difference of reproductive interest has led to sexual conflict in bed bugs. We'll be speaking with Dr. Geoff Parker, an evolutionary biologist credited with developing a theory to explain the evolution of two sexes, about anisogamy, sexual reproduction through the fusion of two different gametes: the egg and the sperm. Then we'll speak with Dr. Roberto Pereira, research scientist in urban entomology at the University of Florida, about traumatic insemination in bed bugs.
