Just like the imprinting of baby geese, so do human babies attach to his/her parents after many hours of interac

4、tion. An example of instinctual behavior is that all ants build anthills in the same way, even when they are not raised together, then the anthill building behavior is instinctual and not a learned response. Sex in humans is also instinctual. We are not born with the desire to engage in sexual activ

5、ities, but as we reach puberty, there is a need for sexual stimulation. Even though we might not know what to do, it is instinctual.
