Abstract
The role of biology in psychology changes from animals to humans. Biology determines animal behaviour in natural environments. For humans the biological forces changes to an energizing function. They recede in the background and the higher psychological functions govern consciousness and behavior. Humans do not have to obey the instincts or reflexes, but have the option to do what they decide to do after reflecting on the alternatives. No other species have this ability to the same degree. The difference between Homo sapiens and other species in this regard is not only a distinction in degree it is a distinction in principle. To understand development of language in its relation to thought, consciousness and volatile behavior is essential.

The role of biology in psychology changes from animals to humans
Their higher psychological functions are acquired in a human culture using symbols and signs
The evolutionary approach, which was quite valid for a comparative study of development of the lower psychological functions in the animal world, found itself in something of a blind alley when it tried to study evolution of higher psychological functions among humans as a result of natural circumstances
