This one rather scientifically heavy but not a great problem for the average geoscience graduate.
Results indicate that the Hadean atmosphere would have been CO2 rather than CH4 dominated. Of interest here is that it means that the Earth was a relatively dry rock with a fairly low carbon content.
For similar results look @ Mars which was relatively similar and has not been modified by anything other than reactions incorporating atmospheric gases back into the rock.
