Evidence of intense phosphorus weathering following 'snowball Earth' glaciations raises a further possibility — that this revved-up nutrient cycle drove conditions for the explosion of animal life. See Letter p.1088 Phosphorus is generally thought to be a limiting nutrient of primary productivity in the oceans, and is important in regulating the redox state of the ocean–atmosphere system. Planavsky et al. use the ratio of phosphorus to iron in iron-oxide-rich sedimentary rocks through time to… Expand
