Instead of dwelling on the biological, physiological, or even the genetic aspects of our evolution, "Titans of the Forests" takes a completely different approach, which could be referred to as the unchartered and neglected field of macroevolution. Uniquely captivating, controversial, and very readable, it is the author's contention that we as a species were continuously forced to change our way of obtaining nourishment, or rather our various economies, in order to adapt to the ever-changing world. And as a result of this economic adaptation, our species would then and only then begin to slowly change into the modern humans of today. For much too long, the world's scientific community has directed the discussion of our incredible evolution. As a matter of fact, our species' biological, physiological, psychological, and cultural evolution has been instigated, propelled, and shaped by our economic adaptation to a fluctuating environment. In a very real sense, the scientists are so far into the trees that they have actually ignored the forest. Consequently, we teach human evolution as a hodgepodge of different theories within the realm of microevolution, thus failing to understand or even to recognize the economic thread that binds them altogether. By integrating the timeline of our prehistoric past with that of our earliest known economies (food gathering, scavenging, and nomadism), the author was able to synthesize a sequence of events that illustrates the economic basis of our remarkable ascension and the beginnings of our present day institutions. He not only reveals the genesis behind the cultural forces that exist within every human society, but for the first time, he has created a systematic and holistic approach in explaining the "how" and the "why" we have economically, physiologically, and then culturally evolved. For unlike the rest of the animal kingdom, we have possessed the extraordinary ability to change our economy, which has made us an extremely adaptable species.
