Bacterial navigation on Archean Earth

Metagenomic and phylogenetic analyses of Nitrospirae bacteria, which have compass-like intracellular magnetic particles called magnetosomes, indicate that the gene cluster responsible for synthesizing and arranging magnetosomes within cells may have originated prior to or near the Archean divergence between Nitrospirae and Proteobacteria, suggesting that bacterial navigation via the geomagnetic field may have evolved during the Archean in response to environmental changes on early Earth. - Read at PNAS
