In the article "Scientists Debate RNA's Role At Beginning Of Life On Earth" (R. Lewis, The Scientist, March 31, 1997) on page 14, the following comments should have been attributed to Laura Landweber, an assistant professor of ecology and evolutionary biology at Princeton University: "The ability to isolate new ribozymes from random sequences has fueled a new excitement about the possibility of uncovering early pathways of RNA evolution. Ultimately, this will make the world of possible primordi

Sidebar: RNA's Role at Beginning of Life - For Further Information Before there was life, there were chemicals. The idea that ribonucleic acid (RNA), because of its catalytic capability and multiple roles in protein synthesis, was the chemical that led directly to life is termed the RNA world hypothesis. Although the phrase "RNA world" is generally attributed to Walter Gilbert, Harvard University's Carl M. Loeb University Professor, in a short 1986 paper, the idea of RNA's importance at the beg
