Humans gave up razor-sharp claws, fangs, sense and instincts in favor of intelligence. This brain-power has enabled humans to make the ultimate adaptation; that of making the environment adapt to us. We have domesticated crops and livestock, we irrigate, we wear clothes, build shelters, air-condition or heat our homes.
