Around the world, miles of rock are missing. Could 'Snowball Earth' be the culprit?

1. The timing of this makes me think of the Burges Shale fossils

Apparently, I’m not the only person to think about the correlation of the event discussed in the article and the apparent explosion in the complexity of life at around the same time. The possible explanation of extra nutrients being brought into the oceans because of erosion and the apparent explosion in evolution makes a lot of sense.

As an aside, I find it interesting that more and more evidence keeps appearing that demonstrates that life formed on our planet earlier and earlier. For instance, the appearance of an excess of oxygen dependent minerals at about 3+ billion years ago suggests life might have existed not very long after our planet formed. I wonder what evidence of the evolution of life might have been removed by the glaciation and erosion event discussed in the article. Perhaps soft bodied animals found in the Burgess Shale might have existed much earlier than we believe.
