Evolution in action

Have  you  ever come across the term  a an
antibiotic resistant
. A person took the treatment but didn’t get
better?Let us figure this situation out.Variations exist among
organisms of the same population.A few of this bacteria have a gene
that make them survive when a patient  take this particular
antibiotic.As the rest of the bacteria die  ,the
survived group reproduce   and pass on this  specific to
the next generation. Eventually this
lead to bacterial population of an antibiotic
resistant strain. Check  power point presentation   to
see more examples of this phenomena.
