Metapatterns

If the biosphere really is a single coherent system, then it must have something like a physiology. It must have systems and processes that perform living functions. In Gaia's Body, Tyler Volk describes the environment that enables the biosphere to exist, various ways of looking at its "anatomy" and "physiology", the major biogeographical regions such as rainforests, deserts, and tundra, the major substances the biosphere is made of, and the chemical cycles that keep it in balance. He then looks at the question of whether there are any long-term trends in the earth's evolution, and examines the role of humanity in Gaia's past and future. Both adherents and sceptics have often been concerned that Gaia theory contains too much goddess and too few verifiable hypotheses. This is the book that describes, for scientists, students, and lay readers alike, the theory's firm basis in science.

what is death? A Scientist Looks at the Cycle of Life Answering the question "What is death?" by focusing on the individual is blinkered. It restricts attention to a narrow zone around the individual body of a creature. Instead, how expansive is the answer we receive when we look at the context of death within the biosphere. Death now is tied to all of life, via the atmosphere and ocean. Death supports the awesome biological enterprise of making abundant the green and squiggly life. Talk about death has headed us straight into a contemplation of life, not only individual life, but big life, life on a global scale. Death and life are neatly dovetailed by the supreme cabinetmaker of evolution. Again, the crucial feature is not the death of any one creature per se, but rather what is done with death. To reach into the meaning of death, we must reach out into the wider context of which death is a part.

What Is Death

Dorion Sagan

On DEATH . . . What is shared by spawning Pacific salmon, towering trees, and suicidal bacteria? In his lucid and concise exploration of how and why things die, Tyler Volk explains the intriguing ways creatures-including ourselves-use death to actually enhance life. Death is not simply the end of the living, though even in that aspect the Grim Reaper has long been essential to natural selection. Indeed, the exquisite schemes and styles of death that have emerged from evolution have been essential to the great story from life's beginnings in tiny bacteria nearly four thousand million years ago to ancient human rituals surrounding death and continuing to the existential concerns of human culture and consciousness today. Volk weaves together autobiography, biology, Earth history, and results of fascinating studies that show how thoughts of our own mortality affect our everyday lives, to prove how an understanding of what some have called the ultimate taboo can enrich the celebration of life. . . . and SEX In Sex, Dorion Sagan takes a delightful, irreverent, and informative romp through the science, philosophy, and literature of humanity's most obsessive subject. Have you ever wondered what the anatomy and promiscuous behaviors of chimpanzees and the sexual bullying of gorillas tell us about ourselves? Why we lost our hair? What amoebas have to do with desire? Linking evolutionary biology to salacious readings of the lives and thoughts of such notables as the Marquis de Sade and Simone de Beauvoir, and discussing works as varied as The Story of O and Silence of the Lambs, Sex touches on a potpourri of interrelated topics ranging from animal genitalia to sperm competition, the difference between nakedness and nudity, jealousy's status as an aphrodisiac and the origins of language, Casanova and music, ovulation and clothes, mother-in-law jokes and alpha females, love and loneliness. A brief, wonderfully entertaining, highly literate foray into the origins and evolution of sex. Two books in one cover, Death & Sex unravel and answer some of life's most fundamental questions.
