Abstract

Based on the Earth’s historical and experimental facts reviewed in the previous chapter, a new hypothesis of the origin of organic molecules, ’the Big Bang” hypothesis of organic molecules, is proposed here; i.e., a large amount of organic molecules were produced in the post-impact plumes of heavy bombardment of meteorites on the ocean between 4.0 and 3.8 b.y.a. The reality of the hypothesis is experimentally confirmed by impact experiments. In various organic molecules so formed, bioorganic molecules could only survive by their water-soluble and clay-affinitive natures. This was the first natural selection in molecular evolution toward the birth of life

Footnote of Preface

“Graphene” is a layered hexagonal network structure peeled off from graphite (Fig. 5.3), while layers curled into a cylindrical shape are carbon nanotubes. If carbon atoms form pentagonal and hexagonal structures then spherical molecules with shapes similar to a soccer ball may be formed. These are known as fullerenes. They are carbon polymers of nanometric dimensions.
