Human History as a Petri Dish
An analysis of human nature and the systematic behavior of civilizations from a macrobiological perspective.
By: Humberto Cares
Premise of the Analysis
Under the hypothesis that Earth functions as a large Petri dish under observation, the traditional human scale — with its moral discourses, empires, and tragedies — fades away to reveal strictly biological behavior. From this naturalistic and systemic approach, historical events cease to be ethical tales and instead become bacterial growth curves, where power is held by the colony that demonstrates the greatest capacity for adaptation, assimilation, and domination.
Phase Analysis: Civilizations vs. Bacterial Culture
1. Lag Phase (Latencia)
• Bacterial Behavior: Bacteria adapt to the new medium, synthesize enzymes, and explore available nutrients without multiplying sharply.
• Equivalent in Human History: The dawn of civilizations and the Neolithic era. Nomadic human groups settle down, domesticate agriculture and fire, and slowly adapt to their environment.
2. Log Phase / Exponential (Exponencial)
• Bacterial Behavior: Massive consumption of resources. Accelerated multiplication. Colonies expand aggressively and clash with each other for space.
• Equivalent in Human History: The Age of Empires (e.g., Macedonia, Rome, Spain). Violent territorial expansion and colonization. Power is the instinct to devour the rival’s substrate.

3. Stationary Phase (Estacionaria)
• Bacterial Behavior: Nutrients become scarce, and metabolic waste accumulates. The birth rate equals the death rate.
• Equivalent in Human History: Globalization and the Technological Ceiling. Today’s interconnected world. With no more continents left to conquer, the system seeks stability under laws and institutions.
4. Death Phase (Muerte)
• Bacterial Behavior: The medium becomes toxic due to the excess of toxins secreted by the bacteria themselves. Mass lysis or extinction occurs.
• Equivalent in Human History: Civilizational Collapse. Global systemic failures caused by the overexploitation of the environment, wars of total exterminion, or human-induced environmental collapse.
Systems Analysis Conclusions
1. Laws and Morals as Chemical Signals
What we call “law,” “religion,” or “cooperation” in civilization functions identically to bacterial quorum sensing. These are cellular autoinduction mechanisms through which the population coordinates its collective behavior to optimize and prolong the exploitation of the substrate.
2. The Inevitability of the Clash
Through this microscopic lens, conflict and assimilation are simply the natural friction at the borders of two expanding colonies. The group with more efficient metabolic or technological tools assimilates the energy of the adjacent, weaker organism.
3. The Paradox of Instinctive Power
Although power is structurally wielded by whichever entity has the capacity to take it, evolutionary biology demonstrates that pure, short-term aggression usually destroys the medium itself. Colonies of organisms that develop reciprocal altruism and stabilize their environment manage to delay the system’s inevitable death phase.
