THE ABUNDANCE OF AMINO ACIDS IN THE HADEAN ERA SET THE STAGE FOR LIFE!

When I was formulating this theory, I thought I would need to convince the reader that meteorites delivered most of the amino acids needed to initiate Emergent Chemical Evolution (ECE). But thanks to Z. Martins and others I do not have to try so hard anymore; because back in 2007 they wrote an article on this very subject. In which they claim that the amino acids delivered by chondrites would have played a part in starting life on earth . This is one of the central claims of Emergent Chemical Evolution. The necessity of some scientists to prove how amino acids were produced on Earth from scratch seems to be totally unwarranted. Especially when, for over thirty years, it has been commonly known that chondrites contain, since before the formation of the solar system, over seventy different types of amino acids. And there is overwhelming evidence that there was a period of heavy bombardment just prior to the emergence of life. I propose that these meteorites were the primary source o...

Nature's Modular Molecules

These are Molecules that are Easy to String Together, Can Catalyze Any Reaction, and Themselves Be a Source to Make More Molecules. When I was reading my biochemistry text it struck me as very odd of how little it discussed about exactly how RNA and then DNA are synthesized! There was only ONE paragraph on the subject. All it said was that the synthesis of all biomolecules, in cells, BEGINS with the MODIFICATION OF AMINO ACIDS! That was the complete discussion on the synthesis of (and amino acids role in) the synthesis of non-protein molecules. Pay attention here is the key concept: if Life Evolved and by our best estimates has blundered onto the most efficient way to synthesize molecules shouldn't we begin from there? Now shouldn't it make you take notice that life not only breaksdown its food to amino acids, begins all its synthesis with the modifications of amino acids, carries out all its important reactions with amino acids(as proteins), and the most abundant organic m...
