How We Have Turned Into Another Species

In the first part of this book I discussed how the human brain developed dueto the development of language;In the second part, I analyzed all aspects which are mentioned below.-prehistoric humans lived in a terrestrial atmosphere were C14 isotope concentration was intermittently higher than usual because a chain of geomagnetic events occurred in this epoch;-the C14 isotopes were incorporated into plants, and transmitted by ingestion to animals in the form of C14-Glucose;-biological processes involving C14-Glucose in humans conducted to a reduction of organic production of nitric oxide;-a lesser apport of nitric oxide favored a healthier cellular development that decreased the sensitivity to viruses and pathogens; this aspect helped humans to migrate and better adapt to new environments;-but for the most of it, the decline of nitric oxide led to significant increases in neurogenesis that stimulated the brain plasticity, but also, it favored a chain of biological changes in the human brain;-all these changes together made the human brain to develop a language;-the language development introduced the features of assembling and disassembling; these features are those implied in producing every technology we ever imagined;-the unique mechanism involved by language delivered the imagination on which is based our civilization.
