Geerat Vermeij, a paleoecologist and evolutionary biologist, talks about power as a driving force in the history of life. He discusses how power has evolved in different organisms, the role of power in human history, and the need to curb our power. The podcast explores topics such as power dynamics, agency in evolution, and the perils of human power monopoly.
Power has steadily increased throughout the history of life on Earth, driving the innovation and success of different species.
Contingency plays a role in shaping individual clades, but underlying principles like power and natural selection lead to predictable patterns in evolution.
Deep dives
The Benefits of Increased Power in Evolution
The podcast episode explores the concept of power as a defining feature of life and its role in the evolution and diversification of species. It suggests that increases in power have been a major driving force behind the innovation and success of different lineages throughout the history of life on Earth. Examples such as the evolution of flight and the symbiotic partnerships between organisms are discussed to highlight how power has played a crucial role in shaping the diversity of life. The episode emphasizes that power is not only linked to physical attributes like size and speed but also to the ability to use and exploit resources effectively. It also addresses the potential risks and challenges associated with the human monopoly of power on the planet, highlighting the need for sustainable practices and global regulation to minimize detrimental impacts.
Contingency and Predictability in Evolution
The podcast delves into the role of contingency in the evolutionary history of life on Earth. Contingency refers to the influence of historical events and chance on the trajectory of species and their characteristics. While contingency is recognized as a dominant factor in shaping individual clades and evolutionary paths, the podcast argues that there are also overriding principles, such as the pursuit of power and natural selection, which operate at a larger scale and can lead to predictable patterns in evolution. It suggests that while the occurrence of specific events may be contingent, the overall direction of evolution is influenced by underlying principles that can be identified and understood.
The Uniqueness of Human Power
The podcast examines the unique power of humans as a species and the factors that have contributed to the unprecedented level of power they possess. It highlights sociality, the use of different energy sources, and the utilization of external tools as key factors that have propelled humans to accumulate and exert more power compared to other species. The episode emphasizes the importance of acknowledging both the benefits and perils of human power, including factors such as habitat destruction and modification. It also discusses the need for global and collective action to address the challenges posed by human power and to strive for sustainable practices and resource management.
The Challenges of Sustainable Power and Human Behavior
The podcast explores the challenges of sustainable power and the implications for human behavior. It touches on the necessity of shifting away from a carbon-based energy economy and the potential of renewable and cleaner energy sources to reduce environmental impact. The discussion highlights the importance of overcoming individual and societal barriers to transition towards sustainable practices, such as self-restraint and the reimagining of economic models beyond the pursuit of growth. The podcast emphasizes the need for interdisciplinary collaboration, including economists, to address the complexities of human power and to generate innovative solutions for a sustainable future.
If the tape of life were replayed, how recognizable would today’s species and ecosystems be? How and why does power increase over evolutionary time? How have humans unleashed so much power, and what are the consequences of that power for life on Earth?
In this episode, we talk with Geerat Vermeij, a paleoecologist and evolutionary biologist in the Department of Earth and Planetary Sciences at UC Davis. He is a member of the National Academy of Sciences, and has published over 200 papers and five books. Our conversation focuses on his most recent book: “The Evolution of Power: A New Understanding of the History of Life.” In it, he asserts that power, the amount of energy an organism can take up or expend per unit time, has increased steadily during the history of life on Earth. On the episode, we discuss the idea of power, how species evolve more power, and how humans have unleashed more power than any other species (and whether we need to work on curbing this power).
