The time period within which the related events, recorded in myths and ancient texts, stretches from circa 15,500 years ago, to about 3,000 years ago. It starts with the termination of the last Ice Age, that triggered mega-tsunamis and mega-storms, which left the planet completely devastated, denuded of all trees and foodstuff, and in great many places of soil as well, but with silted up rivers and estuaries, with immense marshes and bogs, with decaying mounds of trees and dead bodies, pumping out carbon and methane into the atmosphere.
The first phase of the massive reclamation project, during which the ancient ecologists dug out river canals, drained marshes and planted continents with trees, took 3,600 years. Their endeavor was terminated by a sudden heat spike, around 11,700 years ago, during which the global temperature soared by at least 7C, and the population had to flee to the northern polar regions to survive, while much of the reclamation efforts were being decimated by the heat. An asteroid impact cooled down the planet around 10,200 years ago.
It was during the excessively hot period that human skulls grew smaller, as people lost about 20% of their brain matter and roughly 50% of their neural connections. This, though, affected the males a lot more and a lot faster, which led to the establishment of matriarchy and of the Amazon queens. They founded, maintained, and protected vast forest reserves against the invading hordes of agriculturalists, who no longer understood the devastating consequences of eradicating forests. Their gradual destruction led to two subsequent warming spikes, circa 7,000 and 4,400 years ago, that in turn destroyed budding civilizations, led to mass migrations and wars.
The second part of the book deals exclusively with the impact the climatic conditions have on human mental capacity, and the negative effects of heat on our brain. It also explains the conditions, including the piezoelectric effect of the glaciers, the ice age had on people and all animals.
