Conditions on the primordial earth


Conditions on the primordial earth
About  3600 million years ago were strikingly different from those found today. The earth’s atmosphere at that time was reducing and not oxidizing as it is today. You would recall from that large quantities of hydrogen, nitrogen, water vapor, carbondioxide, lipids and amino acids were present. The Oparian- Haldane theory suggests that complex organic molecules would have been formed through a series of chemical reactions in the earths primordial soup or we might say Darwin’s warm little pond. The theory also reasoned that make available in the form of heat cosmic rays and lighting to drive these chemical reactions.
