Mineral Evolution

Finding

Earth began with ~60 mineral species from the presolar nebula. Today there are ~5,800 known species. The increase correlates with major geological and biological events: planetary differentiation (~4.55 Ga), plate tectonics (~3 Ga), the Great Oxidation Event (~2.4 Ga), and rise of land plants (~400 Ma). Approximately two-thirds of known mineral species could not have formed without biological mediation — directly (biomineralization) or indirectly (biologically altered chemistry).

Pattern Mapping

Alignment — Geology and biology are not independent domains. Their evolution is coupled. The minerals that exist record the biology that existed, and biological possibilities were constrained by available minerals and chemistry.

Humility — The traditional division between “living” and “nonliving” is useful but not absolute. The mineral world carries the signature of life. Claiming geology is independent of biology exceeds what evidence permits.

Non-fabrication — Hazen’s framework does not claim minerals are alive. It identifies a specific, testable coupling between mineral diversification and biological innovation. Bounded and empirical, not metaphorical.

Status

Relatively recent framework, published in the flagship journal of mineralogy and widely cited. See Hazen & Ferry, Elements 6, 2010. The mapping to the five properties is this project’s structural interpretation.
