Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the advantage of imprinting?
A
provides flexibility
B
allows individuals to benefit from exposure to unexpected repeated events
C
provides a mechanism to learn new behaviors in response to unexpected events without receiving reinforcement.
D
undirected change in the speed of an animal’s movement in response to a stimulus
Explanation: 

Detailed explanation-1: -Imprinting is proposed to have evolved because it enhances evolvability in a changing environment, protects females against the ravages of invasive trophoblast, or because natural selection acts differently on genes of maternal and paternal origin in interactions among kin.

Detailed explanation-2: -Imprinting is a form of learning in which an animal gains its sense of species identification. Birds do not automatically know what they are when they hatch – they visually imprint on their parents during a critical period of development. After imprinting, they will identify with that species for life.

Detailed explanation-3: -Birds and mammals are born with a pre-programmed drive to imprint onto their mother. Imprinting provides animals with information about who they are and determines who they will find attractive when they reach adulthood. Imprinting has been used by mankind for centuries in domesticating animals and poultry.

Detailed explanation-4: -According to Lorenz the two most important characteristics of imprinting are irreversibility (the property that after imprinted by a specific object, the organism would always prefer the object to other stimuli) and the existence of critical period.
