Previous studies have documented the presence of phosphite, a reduced and highly soluble form phosphorus, in serpentinites, which has led to hypothesis that serpentinizing hydrothermal vents could been an important source bioavailable phosphorus for early microbial communities Archean. Here, we test this by evaluating genomic hallmarks usage living modern with without influence from serpentinization. These analyses are combined results geochemical model calculates speciation during serpentinization as function temperature, water:rock ratio, lithology at thermodynamic equilibrium. We find little no evidence phosphite use environments Voltri Massif or Von Damm field Mid Cayman Rise, but relatively more Lost City field, Coast Range Ophiolite Microbial Observatory, The Cedars, chimney samples Old Prony Bay well non-serpentinizing Axial Seamount. Geochemical modeling shows production is favored ca 275°C-325°C low ratios, may explain previous observations serpentinite rocks; however, most initial phosphate trapped apatite serpentinization, suppressing absolute yield. As result, supported growth around olivine minerals walls suspended aggregates, it unlikely fueled substantial primary productivity diffusely venting fluids life's origin evolution Archean unless substrates equivalent dunites (composed > 90 wt% olivine) were common.

Microbial life has dominated Earth’s history but left a sparse fossil record, greatly hindering our understanding of evolution in deep time. However, bacterial metabolism signatures the geochemical most conspicuously Great Oxidation Event (GOE). We combine machine learning and phylogenetic reconciliation to infer ancestral transitions aerobic lifestyles, linking them GOE calibrate time tree. Extant phyla trace their diversity Archaean Proterozoic, families prior Phanerozoic. that were ancestrally anaerobic adopted lifestyles after GOE. cyanobacterial ancestor, likely predated GOE, which may have facilitated oxygenic photosynthesis.

In recent years, phylogenetic reconciliation has emerged as a promising approach for studying microbial ecology and evolution. The core idea is to model how gene trees evolve along species tree explain differences between them via evolutionary events including duplications, transfers, losses. Here, we describe provides natural framework genome evolution highlight applications ancestral content inference, the rooting of trees, insights into metabolic ecological transitions they yield. Reconciliation analyses have elucidated diverse lineages, from Chlamydiae Asgard archaea, shedding light on adaptation, host-microbe interactions, symbiotic relationships. However, there are many opportunities broader application in microbiology. Continuing improvements make models more realistic scalable, integration metadata such habitat, pH, temperature, oxygen use offer enormous potential understanding rich tapestry life.
