Evolving minerals

The theory seems reasonable to me. To quote:

“Biochemical processes may thus be responsible, either directly or indirectly, for most of the Earth’s 4,300 known mineral species,” the study states.

“Mineral evolution is obviously different from Darwinian evolution-minerals don’t mutate, reproduce or compete like living organisms,” said Hazen in a statement announcing the study’s findings. “But we found both the variety and relative abundances of minerals have changed dramatically over more than 4.5 billion years of Earth’s history.

“For at least 2.5 billion years, and possibly since the emergence of life, Earth’s mineralogy has evolved in parallel with biology,” Hazen added. “One implication of this finding is that remote observations of the mineralogy of other moons and planets may provide crucial evidence for biological influences beyond Earth.”

One wonders, if this is the case, how much the growing subterranean biomass has influenced this “evolution.” This is the theoretic, super-massive collection of various single-cell and small multi-cellular that may exist in pockets / layers between the earth’s crust and mantle. If such a thing does exist (as of yet, still unproven), it is estimated that the biomass would exceed all other life on earth (sea, land, and air). The real Living Gaia, so to speak.
