Final answer:
The false statement about imprinting is that it is limited to birds, whereas imprinting also occurs in other animals including mammals and some fish.
Step-by-step explanation:
The false statement about imprinting is d) Imprinting is limited to birds. Imprinting is indeed a form of learning and it does occur during a critical period in an animal's development. It is typically irreversible once established. However, the assertion that imprinting is limited to birds is incorrect because this process is also known to occur in other animals, including mammals and some species of fish. For instance, whooping crane chicks undergo imprinting with the first few objects they see which can include human caretakers if they are not wearing appropriate disguises to encourage proper species identification for the chicks. Thus, while commonly observed in birds such as ducks and cranes, imprinting is not exclusive to the avian family.
