The speed of the evolution of bacteria is rapid, as it multiples very rapidly, with corresponding changes of generation. It is natural that species of bacteria develop resistance to antibiotics within a short period, given the rapidity of its multiplication.
Humans, on the other hand, cannot reproduce so rapidly. The human evolution has taken another strategy.
Human evolution is characterized by sustainability, supported by the longevity of individuals. Although the "self" maintains its identity over decades, the elements that compose the self multiply and perish within a very short period.
Humans, in a sense, is a "habitat" in itself, in which the evolution of constituent entities occurs. Humans evolve most efficiently when behaving like a swarm of bacteria.
