Editing Diatom (section)

===Relation to grasslands ===
The expansion of [[grassland]] [[biome]]s and the [[evolutionary radiation]] of [[grass]]es during the [[Miocene]] is believed to have increased the flux of soluble silicon to the oceans, and it has been argued that this promoted the diatoms during the Cenozoic era.<ref>{{cite journal |doi=10.1126/science.1095964 |pmid=15256663 |title=The Evolution of Modern Eukaryotic Phytoplankton |journal=Science |volume=305 |issue=5682 |pages=354–60 |year=2004 |last1=Falkowski |first1=P.
