D. W. G. Ballentyne,D. R. LovettVenus..Mars is a more complicated situation. Applying the reduced early surface model to Mars can explain several features that are otherwise difficult to understand. The lack of a proportionately comparable volatile inventory on Mars may be due to a lower level of degassing because of less thermal

Ocean Basin and Continental Evolution,uld have largely been into the global ocean. This is an important factor in considering the chemical processes that would have occurred during degassing of most of the early Earth’s volatiles. It is likely that the earliest prebiotic molecules were formed at the same time as much of the primordial d

The Miller-Urey Experiment and Prebiotic Chemistry,ilability of specific active molecules such as polyphosphates. These requirements suggest that Darwin may have been correct in pointing to some kind of isolated surface pond loaded with suitable precursor compounds. Even if the early ocean was greatly enriched in organic compounds, as suggested by t

A Pathway to the First Organism, matches, it is possible to 1) determine possible “ancestral” sequences of tRNA, 2) translate the tRNA sequences into possible small polypeptides, and 3) compare these short (25+ amino acid) polypeptides to sequences of modern proteins. Interestingly, this process leads to several striking matches b
