B53A:
Advances in Origin of Life Research Posters

Submit an Abstract to this Session



Session ID#: 25705

Session Description:
The origin of life on earth is one of sciences great unanswered questions. This session will address the conditions and pathways under which organic molecules begin to exhibit autocatalysis and the processes by which the information behind these chemical reactions can be stored. Novel insights from laboratory experiments, geological observations, and thermodynamic considerations are helping better understand how life originated on earth and may originate in the universe. Example areas of interest include: 1) Fossil evidence for the origin of life on earth, 2) Laboratory research, 3) Catalytic substrates, 4) Thermodynamics of ancient environments and chemical reactions, 5) The origin of a genetic code, and 6) Analysis of prebiotic chemical pathways.
