I must say I always as geologist have explained myself CO2 changes at Earth's History in terms of Wilson Cycle. And I always thought biosphere is adapted to geology. But from two questions I link at the botttom, I start to think biology may has had a considerable role in those changes.

I formulate my question as: has biology influenced a lot biochemistry of Earth's Carbone atmosphere, or conversely all those changes can be explained just with Plates Tectonic?
