- Although many scientists have long speculated that those pioneering cells arose in the ocean, recent research suggests that the key molecules of life, and its core processes, can form only in places such as Jezero — a relatively shallow body of water fed by streams.

Jan 1, 2014 · Steady and irreversible loss of H 2 is essential to chemical evolution, hence, and chemical evolution can take place only in small bodies which have both an atmosphere and solid surface, with smaller or larger pools of some liquid around. These celestial bodies might be either planets, dwarf planets or large moons among which the latter offer ...

Mar 17, 2017 · Chemists may believe chemical evolution pertains to how oxygen or hydrogen gases "evolve" out of some types of chemical reactions. In evolutionary biology, on the other hand, the term "chemical evolution" most often is used to describe the hypothesis that organic building blocks of life were created when inorganic molecules came together.

Dec 31, 2012 · The difficulty arises because historic events, once they have taken place, can only be revealed if their occurrence was recorded in some manner. Indeed, it is this historic facet of abiogenesis that makes the OOL problem so much more intractable than the parallel question of biological evolution.

For tens of millions of years after Earth’s formation, life (perhaps little more than large molecules, like the viruses of today) probably existed in warm, nutrient-rich seas, living off accumulated organic chemicals.
