> A widely accepted explanation for this peak in coal production is a temporal lag between the evolution of abundant lignin production in woody plants and the subsequent evolution of lignin-degrading Agaricomycetes fungi, resulting in a period when vast amounts of lignin-rich plant material accumulated. Here, we reject this evolutionary lag hypothesis, based on assessment of phylogenomic, geochemical, paleontological, and stratigraphic evidence. https://www.pnas.org/doi/10.1073/pnas.1517943113#:~:text=The%20evolutionary%20origin%20of%20lignin,the%20evolutionary%20lag%20model%20(13 https://www.pnas.org/doi/10.1073/pnas.1517943113#:~:text=The...
