New Theory On The Mystery Of The Origin Of Life Proposed By Weizmann Institute Scientists

Summary:
Experiments mimicking the conditions on Earth billions of years ago have shown how such chemical units, e.g. some of the building blocks of proteins and RNA, could appear spontaneously. Yet, the emergence of proteins or self-replicating RNA molecules remained enigmatic. This started Prof. Doron Lancet of the Crown Human Genome Center in the Weizmann Institute of Science, and his students, Daniel Segre and Dafna Ben-Eli, on a journey leading to alternatives to proteins and RNA.

REHOVOT, ISRAEL (June 5, 2000) -- One of the greatest mysteries, which continuously fascinates many scientists worldwide, concerns the way by which life emerged on primeval Earth. The accepted notion is that prior to the appearance of living organisms, there was a stage of chemical evolution, which involved selection within inanimate chemical mixtures. This is thought to have eventually led to the crucial moment, when self-replicating molecules arose. As self-replication is a most fundamental characteristic of living entities, such an event is often defined as the birth of life.
