Biological Constraints in Learning

In the field of psychology, particularly in the study of learning, it is understood that organisms have inherent biological constraints that can limit the types of learning they are able to achieve. These constraints can result from evolutionary adaptations that predispose species to learn certain associations more easily than others. For instance, consider two scenarios involving two distinct species: a raccoon trained to engage in a complex task that requires it to manipulate objects and a parrot taught to mimic human speech. Which of the following examples best illustrates the concept of biological constraints in learning?
