ReadMe of Blank2009c.NotSoOldArchaea.msq This file was created in Mesquite (mesquiteproject.org) in September 2009. Prepared for Submission to DataDryad.org using Mesquite version 2.75, September 2013. Published as Figures 3, 4, 5, and 6 in the article: Not so old Archaea - the antiquity of biogeochemical processes in the archaeal domain of life. Carrine E. Blank Geobiology 7:495-514 (2009) doi:10.1111/j.1472-4669.2009.00219.x Character Matrix 1: Nucleotide Sequence Matrix Character Matrix 2: Categorical Data Matrix Optimal growth temperature (ordered multistate character) Optimal pH of growth (ordered multistate character) Habitat/Salinity (ordered multistate character) Methanogenesis (binary character) Sulfur reduction (binary character) Sulfur oxidation (binary character) Sulfide oxidation (binary character) Sulfate/Thiosulfate reduction (binary character) NifH nitrogenase gene in genome (binary character) Nitrate reduction (binary character) Oxygen metabolism (binary character) Tree Window: Phylogenetic tree topology was reconstructed using a 100-gene concatenated dataset. Branchlengths were first inferred using maximum likelihood, then scaled to age using penalized likelihood (using r8s). The scale bar shows the median node age in millions of years before present.
