A theory might be a modest contribution in which we assume that the most important factor in the emergence of man was not the natural selection among individuals but the selection among individualized proto‐cultural groups. The emergence of group awareness helped the use of symbols which led to the rise of language and abstract thinking. The personality of modern man is the interacting component of group cultures which is a complex autonomous system. Individuals and the group mutually define each other. The harmony of these interactions has broken down when modern societies had been formed and this is the final cause of the most of our problems in the present time.

Subjects were faced with an approaching woman (Stranger) who showed definite signs of friendliness and threat during alternate approaches. Observations consisted of two episodes: the Stranger either approached the dog in normal speed of walk while talking to it and finally petted it gently (Friendly approach episode) or she moved slowly and haltingly and looked steadily into the eyes of the dog without any verbal communication (Threatening approach episode).

The inheritance of the behavioral elements was investigated employing a five-times-replicated diallel cross among three inbred strains. A detailed Hayman analysis of variance and a variance-covariance analysis were performed to uncover the genetic architectures of these phenotypes. Additive genetic effects and/or ambidirectional dominance was found to be characteristic of most species-specific behavioral elements studied, suggesting an evolutionary history of stabilizing selection.

The average positions (distance from predator's tank) of guppies was influenced by the presence of a preadator, but the effect of previous experience with a predator was manifestated only in the presence of predator. The average position of guppies also depended on the mirror-treatment (changing the length and position) but it was influenced only by the length but not the angle of mirror. The relative independence of the position of the mirror observed in the guppies' behaviour challenges the basic assumption (i.e. closer to the predator by long parallel than short angled mirror) is indeed the result of TFT as interpreted earlier. Instead, the effect of mirror treatment appears superpositioned on the predator inspection as an independent variable. In light of these results we discuss the usefulness of mirror systems in testing predator inspection as TFT-like behaviour.
