Philosophy of Medicine – Lesson. 54 – Theory of Human Nature

Man’s “Evolution” from ape-like ancestors is thought to be the key to our true Human Nature. Ethology or the scientific study of Animal Behavior is based on the Theory of Evolution. In order to explain human condition, Ethological Theories of Human Nature appeal to the “evolutionary” past of man.
However, it is important to know that Lorenz made no scientific study of Behavior displayed by Apes. Among the members of Homo genus, Man is the only surviving representative of the Homo sapiens Species and hence it will not be easy to validate his conclusions about evolutionary origin of innate Human Aggressive Behavior. If Aggression is viewed as Hereditary Behavior which is based upon its Survival Value for the genes for that Behavior, it must be noted that there are no surviving human ancestral Species. It appears that Aggressive Behavior had no value in defending survival of Members of Hominin Family, immediate ancestors of Anatomically Modern Man.
