Lenski's work with E. coli has also led him into the digital world. Using computers, Lenski can achieve precise, rapid results by manipulating digital organisms. Software that evolves much like bacteria in the real world.
Microbes are great tools to study evolutionary biology. The ability to carry out long term experiments in both model and complex systems, and derive genome information from progeny strains has revolutionized the study of evolution.
A lecture by James Shapiro, PhD, Department of Biochemistry and Molecular Biology, University of Chicago, outlines some of the biological activities cells use for generating novel configurations of their read-write genomes.
Predatory bacteria have a particular protein that protects them from their own prey-damaging enzymes
Charles Ofria and his colleagues have created a program called Avida in which digital organisms can multiply and evolve. They are studying many of evolution's deepest questions, such as how complexity evolves from simplicity and why individuals make sacrifices for each other.
While you may have heard of our own "body clock" that tracks the 24-hour cycle of the day, it turns out that some bacteria can tell time, too.
R. Ford Denison is an evolutionary biologist who's interested in how to make agriculture better. The ways in which plants thrive or fail are shaped by their evolutionary history, as well as the evolution that unfolds every planting season.
