Change in species is described as a process that usually occurs over long periods of time. yet, even though antibiotics have only been widely used for fifty years, scientists recognize that overuse of antibiotics has led to antibiotic-resistant strains of bacteria. the reason this can occur in a relatively short span of time is that -

The reason that this can occur in a relatively short time span is because of the speed of bacteria reproduction. They are able to reproduce rapidly which means they can evolve to be resistant to the antibiotics created.
