From the groundbreaking partnership of W. H. Freeman and Scientific American comes this one-of-a-kind introduction to the science of biology and its impact on the way we live. In Biology for a Changing World, two experienced educators and a science journalist explore the core ideas of biology through a series of chapters written and illustrated in the style of a Scientific American article. Chapters don’t just feature compelling stories of real people—each chapter is a newsworthy story that serves as a context for covering the standard curriculum for the non-majors biology course.  Updated throughout, the new edition offers new stories, additional physiology chapters, a new electronic Instructor's Guide, and new pedagogy.

shared equally between atoms, causing a partial negative charge at one end and a partial positive charge at the other; for example, water. Hydrogen bond A weak electrical attraction between a partially positive hydrogen atom and an atom with a partial negative charge. makes up more than 75% of a cell’s weight. All of life’s chemical reactions take place in water, and many living things can survive only a few days without it. A water molecule—H2O—is shaped like Mickey Mouse’s head (the oxygen

That is the greatest achievement of life on Earth, and it occurred extremely early in the history of life.” From Heresy to Orthodoxy As soon as her 1967 paper was published, criticism rolled in. Many of Margulis’s colleagues were skeptical, even dismissive, citing a lack of supporting evidence. Most of the evidence that Margulis marshaled in support of her hypothesis was circumstantial rather than direct (the conclusive DNA evidence did not come until 1978). There was philosophical

Energy powers every activity we perform, from the more obvious ones like breathing, thinking, and running to less obvious activities like building the molecules that make up our bodies. Without a source of energy, all life on Earth would grind to a halt, like a cell phone with a dying battery. Organisms can’t simply create energy when they need it, however—energy cannot be
