Signs of Life: A Report Based on the April 2000 Workshop on Life Detection Techniques C Workshop Papers NOTE: The papers in this appendix are published essentially as received from their authors. They therefore should be regarded as a record of the workshop proceedings and not as a refereed work. Where possible, typographical errors, egregious errors of fact, and non-pertinent remarks have been redacted by the Committee on the Origins and Evolution of Life. Listed below by session, the papers are reproduced on the CD-ROM of the full report but are not included in the printed report owing to space limitations.
