Animal sex, however, is a more recent invention. Biologist Lynn Margulis of the University of Massachusetts at Amherst believes the evolutionary roots of egg and sperm cells can be traced back to a group of organisms known as protists that first appeared some 1.5 billion years ago. (Modern examples include...

But Lovelock's formulation is compelling because science now has the tools to explore some of the vast interactions that govern global systems. Although Lovelock first...
Lovelock and Margulis have modified the theory over the years to address scientists' criticism that Gaia implied that the earth acted with a sense of purpose. In its newest form, Gaia has inspired a flood of research into the interaction between living systems and the atmosphere, earth and oceans. At...
Lovelock originally thought that some purposeful design organized living things to stabilize the atmosphere and climate. Now he and Margulis believe this regulation is achieved through the simple mechanism of feedback. For instance, in a hypothetical scenario, Lovelock shows that a planet covered simply by light- and dark-colored daisies...
