The Origin of Life
My previous article did little to describe the early earth that might have made “life” possible, so I will try to describe the situation a little better so that we have a better chance of describing the characteristics of life.
The accepted theory is based on a preparatory chemical evolution where small compounds with reduced carbon atoms were formed. These compounds reacted with the then volatile environment (catalyzed by clay) to form larger amino acids, sugars, and nitrogenous bases to create a prebiotic chemical “soup”. Eventually, large polymers of these compounds created the proteins and complex sugars we are familiar with today.
Life became possible when one of these large, complex molecules (most likely RNA) gained the ability to make a copy of itself. Thus, chemical evolution gave way to biological evolution.
Replication is certainly an important aspect of life because it creates two vital characteristics: selection (survival of the fittest) and ego, but is it what creates life?
