Animals can quickly adapt to changing environmental conditions that impact their food supply. For example, in recent studies of Galapagos finches during a severe drought, small-beaked finches largely died out, because large and hard seeds became dominant. The surviving finch population had measurably larger beaks in one year. It took 15 years of normal conditions for finch beaks to return to their pre-drought length. Wrangham argued that the biological changes attending cooked food would have been immediately evident, and anatomy presented the most dramatic changes seen in the human line. The only other plausible candidate would have been , but it was only a more robust version of .
Book IV of Locke's Essay Concerning Human Understanding.
The rise and fall of Rome is an iconic example of the trajectories of preindustrial civilizations. Only so much surplus can be skimmed from economic systems based on the energy of wood, food, and muscle power. I wanted to cover some civilizations in detail to make the pattern clear, and will largely only survey other preindustrial civilizations, as the dynamics were similar, but with some important variations.

Paleobiologists are fascinated with the history of life on Earth, and I share their sense of wonder. If I can impart the slightest sense of that to my readers, this essay's first half will be successful for that alone. However, just as a math curriculum builds on itself, as each class forms the foundation of the next one, this essay's first half is intended to help readers develop a foundational understanding. With that foundation built, the information in this essay's last half can make a profound impact and help readers achieve personal paradigm shifts. That is essentially this essay's purpose. Studying this essay's first half is far from a waste of time for those whom I seek, but is vitally important.

Did the larger brain lead to the behaviors, or did the behaviors lead to the larger brain? If other evolutionary trends have relevance, they mutually reinforced each other and provided positive feedbacks; down one evolutionary line it reached conditions that led to the human brain. The initial behavior was probably the use of a body part (the brain) for a new purpose, and its success led to selective advantages that led to mutual reinforcement. Although it is by no means an unorthodox understanding, I think that the likely chain of events was walking upright freed hands for new behaviors, which led to new ways of making and using tools, which enhanced food acquisition activities. This allowed the energy-demanding brain to expand, as well as related biological changes, which led to more complex tools and behaviors that acquired and even more energy. That, in short, defines the human journey to this day, which the rest of this essay will explore. There has never been and probably never will again be an energy-devouring animal like humanity on Earth, unless it is a human-line descendant.

Few people on Earth today have much understanding of the relationship between . Most people think that money runs the world, when it is only an accounting fiction.

Understanding this essay's first half will help with comprehending the last half, and the connections between energy, ecosystems, and economics should become clear.
