There are a
lot of created theories in which biologists engaged themselves to explain such
phenomenon that occurred thousands of years ago, and experts say such study is
hard to replicate, the start of prokaryote cells. Prokaryotes were said to be
the first organisms that existed and were able to exhibit photosynthesis that produced
oxygen that spread across the atmosphere. Hence, consider the Theory of Spontaneous formation of organic molecules which suggests that the
early earth had less to none oxygen. Thus, the atmosphere was abundant with the
gases, CO2 and N2 with some
other small amounts of H2, H2S, and CO. Hence, in Stanley Miller’s experiment
when electrical sparks or “lightning” came in contact with these gases, the
newly formed mixtures of CH4, NH3, and H2 were catalyzed. With these newly formed gases in interaction
with H2O came the first synthesized some amino acids that compromised the earliest organic
molecules which evolved to macromolecules, to be organelles of a cell. Which in the latter macromolecules
are in today, maybe have been before the early nucleic acids (able to
replicate) or proteins of these early cells.
