Within evolutionary line of vertebrates, correlation between the degree of differentiation of the brain and peculiarities of the formation of complex behavioural acts may be observed. Gradual evolution in the organization of complex motor food-searching conditioned reflexes and the capacity to visual discrimination was revealed in phylogenetic line of vertebrates: elasmobranchs (rays and sharks), marine teleosts, reptiles (terrestrial tortoises), insectivores (hedgehogs), rodents (rats) and primates (lower monkeys).
