ABSTRACT
Every single act in the life of an organism, no matter how trivial, whether of the organism as a whole or of any part of it, must have some significance for the organism itself, because it is part and parcel of the life itself. Every act in an organism’s life has some significance for that life. The principles of maladaptive action are seen to be factors in animal evolution, regardless of whether man is or is not involved as one of the environmental factors. An example of self-injury through failure to readjust after interruption of activities of the instinctive routine type relates to one of the wolf spiders (Lycosidae) and is taken from Warburton. The presentation of self-injury among insects due to excessive activity will have to limit itself to one example of excess in pursuit of food, and to one example of excess in connection with mating.
