[Ethological approach to seasonal depression and manic-depressive psychoses].

Some psychotherapists disagree with the importance of seasonal factors and sunlight in the etiology of depressions and bipolar disorders. Depression in spring and summer, mania in autumn and winter do not seem consistent with the expected effects of light on mood. Ethology offers an explanation: the variations of photoperiod can have opposite effects, depending on individuals, on territorial and hierarchical tendencies which constitute biological roots of mood disorders.

[Ethological approach to menopause: an introduction to evolutionist medicine].

Menopause is a phenomenon particular to the human species. It exists in nature only in very few animals. In an evolutionist view, it appears as an adaptation, the function of which was to protect prehistoric women from dangerous late pregnancies and to enhance survival of their last-born child and grandchildren.

[Phylogenetic origin of symptoms in psychopathology. Exemplified by hysteria].

Setting behavioral disturbances affecting humans in a natural environmental context indicates the presence of phylogenetic components in their etiology. Hysterical conversion disorders provide a good illustration. The biological model to which they can be traced seems to be the "distraction display," originally intended to deceive predators and lure them away from the offspring or threatened related individuals. Hysterical tendance to draw attention on oneself could thus paradoxically be seen as performing an altruistic function.
