Evolving Rocks

SpaceAdmiral notes a new study making the claim that rocks have been evolving throughout Earth's history. "'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.'"
