Question Antibiotics and antibacterial products have saved a countless number of lives. With all the good that antibiotics have brought to the world, an unforeseen problem has surfaced. As more antiobiotics are used, bacteria are adapting to the selective pressures imposed on them by humans. Natural selection has acted on bacteria, creating new strains (genetic variants of a species) of bacteria with mutations coding for antibiotic resistance. The new strains produced from the subtle mutations in bacterial DNA over a short period of time can best be described as which type of evolution? A microevolution B macroevolution n artificial evolution D punctuated equilibrium

Prokaryotic evolution

The term evolution means the gradual change or a transformation from a simple or primitive state to a complex or advanced state. Prokaryotic evolution is a concept that involves the evolution of the form and function of most primitive organisms (prokaryotes) through several stages and changes to form diverse life as a part of organic evolution.
