A General Survey of Inorganic Chemistry and the Origins of Life
1. Introduction to the Study of the Origins of Life
In The Beginning...
Theories abound about the Origins of Life. Much like earlier ideas of
spontaneous generation in biology, phlogiston in chemistry, and aether in physics, they
are put forth as the best answers given the available information. Often they are simply
guesses at possible life-forming events. Some are advocated doggedly by prominent
scientists and popular media sources; others are looked on as interesting possibilities
only. There seem to be almost as many theories as there are research groups working in
the field. None to date has proven to be satisfactory to the vast majority, although some
have held the popular consensus for a time. Large gaps exist between one group's area
of research and another's. Thus, it is currently impossible to put forth a "complete"
theory on the origins of life; we simply don't know enough to even begin guessing at all
the necessary components and processes that would need to happen for life to arise.
However, this has not stopped some from trying. In this paper, we shall confine
ourselves to three of the most popular theories on the subject.
Things to consider when proposing a theory
As mentioned earlier, the question of why we are here and how we got here
requires input from very diverse sources. Astronomy, physics, chemistry, geology, and
biology are the most important for our purposes, although other disciplines may also play
significant parts. This requirement stems from a property of the question; how we got
here depends on what things were like before life originated. More specifically, how we
got here depends on what almost everything was like before life originated. We must
therefore consider the conditions not only on the early Earth, but in the primordial solar
Here’s what’s next.
