If you liked the Cold Spring Harbor subject collection on the origins of life, this collection on RNA World topics will also make you happy.
For the KrisBob trolls out there, here's a quote from Steven Benner's article "Setting the Stage: The History, Chemistry, and Geobiology behind RNA"
| Quote | | No community-accepted scientific methods are available today to guide studies on what role RNA played in the origin and early evolution of life on Earth. Further, a definition-theory for life is needed to develop hypotheses relating to the “RNA First” model for the origin of life. Four approaches are currently at various stages of development of such a definition-theory to guide these studies. These are (a) paleogenetics, in which inferences about the structure of past life are drawn from the structure of present life; (b) prebiotic chemistry, in which hypotheses with experimental support are sought that get RNA from organic and inorganic species possibly present on early Earth; ( c) exploration, hoping to encounter life independent of terran life, which might contain RNA; and (d) synthetic biology, in which laboratories attempt to reproduce biological behavior with unnatural chemical systems. |
Science, he's doin it rite.
