The lack of a proportionately comparable volatile inventory on Mars may be due to a lower level of degassing because of less thermal

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

These requirements suggest that Darwin may have been correct in pointing to some kind of isolated surface pond loaded with suitable precursor compounds.

Interestingly, this process leads to several striking matches b
