How We Have Turned Into Another Species

<p>In the first part of this book I discussed how the human brain developed due</p><p>to the development of language;</p><p>In the second part I analyzed all aspects which are mentioned below.</p><p>-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;</p><p>-the C14 isotopes were incorporated into plants and transmitted by ingestion to animals in the form of C14-Glucose;</p><p>-biological processes involving C14-Glucose in humans conducted to a reduction of organic production of nitric oxide;</p><p>-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;</p><p>-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;</p><p>-all these changes together made the human brain to develop a language;</p><p>-the language development introduced the features of assembling and disassembling; these features are those implied in producing every technology we ever imagined;</p><p>-the unique mechanism involved by language delivered the imagination on which is based our civilization.</p>
