Microbes adapting to new environments is a big question in biology. Scientists studied E. coli bacteria with high mutation rates to see if they adapt faster. They grew these bacteria in tubes with food for 900 days. Surprisingly, the high mutation bacteria adapted just as well as normal bacteria. Tests showed their mutation rates became similar over time. Even though high mutation bacteria changed their DNA more, it didn't help them adapt faster. Both types of bacteria had similar changes in their DNA related to forming biofilms and controlling gene activity. This study suggests that having more mutations doesn't always mean adapting quicker to new environments.
