Summary:
Explains how scientists believe simple one-celled organisms first emerged on Earth over 3.4 billion years ago and eventually evolved into complex multicellular organisms. Examines the most basic of cells, prokaryotes, and illustrates how one member of that family, blue-green algae, changed the Earth's atmosphere. Analyzes the symbiotic relationship between different cells, a factor that scientists believe led to cell differentiation and the evolution of multicellular organisms.
