Microbial organisms dominate life on Earth, but tracing their early history and evolution is difficult because they rarely fossilize. Determining when exactly a particular group of microbes first ...

Molecular dating and divergence time estimation encompass a suite of analytical frameworks designed to reconstruct the temporal dimension of evolutionary history by translating genetic differences ...

Bacterial evolution and oxygen adaptation: A timeline built from genomic, fossil, and chemical data. Colors show oxygen states: anaerobic (blue), aerobic (red), and proportion of aerobic lineages in ...
