They just build up meaning they have a capability of changing their structure and reacts on the problems the environment presents at the specific times (Simon, 2015).For evolution to surpass, mutation has to take place though it is an extremely slow progression and cannot be rapidly (Simon, 2015). The genes may shift from one population to another and the nonrandom mating may occur quickly but the generic drift occurs by chance randomly. Therefore, it might take a piece before this happens. Moreover, selection varies in different genotypes. It may take a while for individuals in a population to be varied (Simon, 2015).Some bacteria have a mutation that makes them possible to snuff it the penicillin (Simon, 2015). Moreover, the adm inistration of the penicillin changes the environment in which the bacteria reside. The bacteria with resistivity genes will survive this new environment. The resistance genes pass over to several generations due to natural selection (Simon, 2015). Due to the usage of penicillin for many generations, the insubordinate bacteria increase over time. This makes penicillin less effective (Simon,
