Researchers analyzed the history of metabolic genes acquired by E.coli bacteria over 100 million years, finding that approximately 25 genes were added through horizontal gene transfer. This mechanism allows bacteria to evolve new functions and adapt to changing environments, rather than improving existing performance.
