| Abstract: | A mechanism is suggested, based on a biphasic approach-withdrawal theory proposed byT. C. Schneirla, to account for how behaviours may be selected by environmental forces for transmission over generations. The basic postulates of Schneirla's theory are presented followed by an examination of some aspects of lorisid behaviour in the light of this theory. |
