In this seventh edition of the author's iconic work on the evolution of the modern human brain, he delves into the geophysical events that serve as significant catalysts for changes in brain function. Given the global nature of concepts like planetary cooling, Mrejeru's commentary provides insightful commentary on how different parts of the globe adapted to these experiences. Presenting the work as a collection of papers, Mrejeru first transports readers back to 500ka to 300ka (300,000 to 500,000 years ago), a period marked by the Paleolithic, which spearheaded brain anatomical change.
As with prior editions, the level of detail is impeccable and incomparable. It is no less than a window into how modern man came to be. This time, it is further imbued by a final section dedicated to the Information Society and the author's stellar ability to clearly explain the complexities of anthropology, psychology, and chemistry to the avid scholar. How did bipedalism come about? What separates us from apes? What were the origins of something as trivial as fire? Along every turn, Mrejeru's work becomes increasingly like a series of data points that map out every iteration of the human species that culminates with present day homo sapiens.
The author provides a fundamental lesson on key concepts, such as neurogenesis, without which encephalization and greater cognition would not be possible. Further, Mrejeru diligently integrates the renowned work of researchers from countless universities to demonstrate how events such as drastic decreases in atmospheric carbon dioxide or increases in ionizing radiation could be instrumental to brain evolution. At the root level, the work is a classic example of the effect of thought-provoking questions. Throughout the book, Mrejeru delves into riveting analysis, whether of the dichotomy between unconscious thought and conscious awareness or of the impact of entropy on human intelligence. Sometimes it's a discussion on the twenty-four hyperplane dimensions, while other times it's an electrifying foray into comprehending the schizophrenia gene and the effects of psychedelics.
In any case, there is never a dull moment with Mrejeru's work. On the contrary, his hypotheses in each of his papers lead to a novel frame of mind and innovative thought. For instance, the hybrid thinking model he integrated into his final section on the Information Society deftly weaves together social intelligence and technical skills, a modern rendition of what propelled earlier human civilizations to make evolutionary leaps and engage in advanced creative tendencies in their respective time periods. Even more so, the author provides a deeper understanding of nutrition, dietary composition, and the role of inflammation, all highly relevant to brain development in modern society.
Above all else, Mrejeru's work is a documentation masterpiece, capturing the progression of cognitive development throughout human history, from a state of mere survival to a thriving condition where unlocking the full potential of the human mind does not seem far on the horizon. Though the work is anchored in a strong level of abstract and technical thought pertaining to the brain, those who are interested in going down the rabbit hole that is the evolution of the modern human brain will find this experience one that is delectable and infused with valuable insight and commentary from an expert in the field.
