Bacterial evolution

Bacterial evolution is the process by which bacteria change and adapt over time, developing new traits that help them survive in their environments, such as resistance to antibiotics or the ability to digest new food sources. This happens remarkably quickly because bacteria reproduce so rapidly and have relatively simple genetics, meaning beneficial changes can spread through a population within days or weeks rather than the generations it takes larger organisms. Understanding bacterial evolution is crucial for modern medicine and agriculture, as it explains why bacteria become resistant to our treatments and how we might stay ahead of these microscopic competitors.
