Gene Swapping, Not Mutation, Drives Gut Bacteria Evolution
Original: Gene Swapping, Not Mutation, Drives the Hidden Evolutionary Rulebook of Gut Bacteria
A new report says gut bacteria evolve mainly by swapping genes with each other rather than through gradual mutation. Horizontal gene transfer, the exchange of DNA between microbes, appears to shape how intestinal bacterial populations adapt and diversify, following an underlying evolutionary pattern. The finding could influence how scientists study antibiotic resistance and the ecology of the human microbiome, areas where rapid bacterial adaptation matters greatly.
Why now: Fresh research coverage challenges the assumption that mutation is the main driver of bacterial evolution.
