EVOLUTION:
Transitions from Nonliving to Living Matter

Steen Rasmussen, Liaohai Chen, David Deamer, David C. Krakauer, Norman H. Packard, Peter F. Stadler, Mark A. Bedau

Researchers interested in the origins of life on Earth have long pondered what constitutes the transition from nonliving to living matter. In this meeting report, Rasmussen and colleagues discuss two recent workshops that were convened to describe the systems needed to synthesize simple life forms--called artificial cells or protocells--both in the laboratory and as simulations.
