This research presents a global framework for understanding the planetary microbiome by analyzing over 85,000 metagenomes to map how microbes are structured across diverse habitats. By integrating taxonomic and functional data, the study identifies generalist species that possess the unique metabolic versatility required to thrive in multiple, ecologically distinct environments. These generalists act as critical bridges, facilitating horizontal gene flow between disparate settings, such as the transfer of genes from human guts to wastewater and eventually into the broader environment. A key…
