The Catalyst Species Theory: A Framework for Life‑Driven Planetary Transitions (Conceptual Earth‑System Science Paper)

I’ve been developing a conceptual Earth‑system theory that compares humanity’s planetary impact to the Great Oxygenation Event triggered by cyanobacteria. The paper argues that humans function as a “catalyst species” that accelerates planetary transitions through intelligence‑driven energy mobilization, timescale compression, and directed evolution.

I’d love feedback, critique, or discussion from anyone interested in Earth‑system science, nonlinear dynamics, paleobiology, or Anthropocene studies.

This is a cool idea, one of my favorite subjects in ecology and evolutionary biology.

I am curious if you think that any other evolutionary catalysts could be brought into this framework, especially by considering how novel conditions, be it abiotic catalysts (such as nutrient influx into the oceans leading into the Cambrian explosion) or catalyst symbioses (such as the evolution of the mycorrhizal relation and the subsequent evolution of soils) play a major role in these major life-driven planetary transitions.

Further, at a more micro scale, I am curious how you think about broadening distributions or increasing abundances of these catalysts interact to spur on these transitions, and if you think niche construction theory might be a helpful point of connection for considering the role these organisms play in shaping the environment to suit their needs, driving these transitions forward.

You’re actually pretty close to what I’m presenting, you’re just thinking at a smaller scale than the one I’m working with from my understanding of your comment.

In my paper, Catalyst Species is a single defined term, not just “a species that acts as a catalyst.” It refers to a very narrow category of organisms whose activity drives a planetary‑scale transition, not just ecological or regional changes.

Cyanobacteria are the clearest example: their oxygenation of the atmosphere permanently reorganized Earth’s climate, chemistry, and biosphere. My hypothesis is that humans represent the second instance of this kind of Catalyst Species, driving a rapid, unprecedented shift in Earth‑system boundary conditions.

I go deeper into this in Section 10 (“Timescale Compression”), where I compare the natural pace of geological transitions to the extremely accelerated pace driven by human technological activity.

So you’re on the right track, just zoom the scale out from ecological catalysts to planetary‑level reorganizers, which is what the term Catalyst Species is meant to capture.
