In a study of Dr. Lorenz of Austria, there is the record about "the imprinting action of the cancer". One day the doctor observed an egg of the greylag just before the incubation. The young bird was born safely and stared at the doctor with black big eyes. The doctor intended to leave the later care to one goose, but it was vain and failed. It take a doctor to be a parent without doubting the young bird and take you in the back to go to where. An action it hatch and to take the moving thing which it watched first with a parent with is said "imprinting". The young bird runs after it if it show the toy of the robot just after incubation.
