The evolution of diatoms and their biogeochemical functions SUMMARY: This article talks about the evolution, cell structure, and ecological role of diatoms. The first section is an introduction to what diatoms are. The second section talks about the evolution of photosynthesis (from cyanobacteria to eukaryotes with chloroplast). The third section explains the significance of the… Continue reading The evolution of diatoms and their biogeochemical functions

Coal Formation Not Correlated with Fungal Evolution
Delayed fungal evolution did not cause the Paleozoic peak in coal production SUMMARY: This article provides evidence to refute the theory that most of our coal was formed during a period of time (Carboniferous-Permian age, about 299 million years ago) when fungus had not evolved enzymes to digest lignin. Plant material was thought to have… Continue reading Coal Formation Not Correlated with Fungal Evolution
