Low levels of C02 released from 'dead' soil, months and years after it was irradiated, may indicate that "the chemistry of life is not exclusive to life."

The idea that pre-existing, metabolism-like reactions of organic molecules were harnessed and accelerated by early life seems plausible. However, what is not explored in this article however, is that soil itself is at least partially a product of biological activity - rock weathering in the absence of life would produce something different. I can't help but wonder if that would make a difference.

Whiting event (Geology ⛰️)

A whiting event is a phenomenon that occurs when a suspended cloud of fine-grained calcium carbonate precipitates in water bodies, typically during summer months, as a result of photosynthetic microbiological activity or sediment disturbance. The phenomenon gets its name from the white, chalky color it imbues to the water. These events have been shown to...
