What levels (forms) of behavior do you know? How do they change during the evolution of the animal world?

There are five levels (forms) of behavior characteristic of animals. They can be combined into two groups: congenital and acquired. To congenital include permanent (stereotypical) forms of behavior – taxis, reflexes and instincts. They practically do not change throughout life and are most often hereditary. Acquired forms of behavior are those that develop during the life of an individual, – learning and rational activity. As organizations become more complex, congenital forms of behavior gradually give way to acquired ones. For example, taxis appear more often in protists, to a lesser extent in worms, and disappear in primitive mammals. Instinctive behavior prevails in bees, and in dogs it is replaced by learning abilities. The highest level – rational activity – begins to form in lower mammals, increases in higher primates and is maximum in humans.
