Light Wavelength Analysis Nets Purple Earth
Researchers here on the Oblate Spheroid, struggle to explain why microbial evidence throughout the Earth is varied yet so stratified.
The answer may come from the fact that the evolution of microbe life on the earth to date has come down to how these organisms were able to convert certain wavelengths of light.
Simpler structures on early Earth were able to absorb and utilize light from the green spectrum of visible light. If this is true, it suggests that the Earth would reflect light from the red and blue spectrums thus yielding a purple Earth.
Further, if this theory holds up, wavelength analysis may give astronomers greater understanding of the evolution of potential life through biomarkers on distant planetary objects.

What an interesting article... I like how it messes with my whole mental image of prehistoric Earth... does this mean we'll have to re-edit the opening scene of 2001 to reflect a purple sky?

Low to no Oxygen equals purple ... good Oxygen equals green. You bet, re-edit.

So we'd have to give the cave men some space suits, since they wouldn't be able to breathe in the lower oxygen... oh, man. Science is really cool. It makes total sense, though, that oxygen levels would have increased as the earth developed, since volcanic beginnings would not have presented too many forests and jungles... first tiny organisms with hard cell walls, then plankton, and, eventually, venus flytraps.
