A review and evaluation of the rapid evolution of theoretical and empirical knowledge in the interdisciplinary study of the origins of life. With 35 contributions authored by 95 scientists, the text discusses many aspects of the origin of the first cell: exobiology in the solar system and beyond; the early paleontological record; physical, chemical, biological and informational aspects of the origin; and structure of the membrane and the cell itself.
