- Armpit_effect abstract "The armpit effect in biology is a hypothesis that an individual learns to identify closely related individuals by their odor, comparing it to its own smell for phenotype matching. The animal is able to identify subtle genetic distinctions in odor, and this behavior enables an animal to distinguish between kin and non-kin. The theory was proposed by Richard Dawkins who hypothesized that it would be advantageous to an animal to be able to recognize its kin in this way so as to increase its fitness and reproductive success, an example being a mother's ability to feed her own offspring rather than those of another individual. To test whether the hypothesis was true, experiments were performed on ground squirrels, cowbirds and golden hamsters. It was found that juvenile Belding's ground squirrels behaved differently when presented with plastic cubes rubbed with secretions from their relatives as compared to non-kin secretions. An experiment with chicks of brown-headed cowbirds provided evidence of self-referent phenotype matching, but in this case, a visual cue was used rather than an olfactory one. An experiment using young golden hamsters showed that they could recognise kin from non-kin even when, as infants, they had been removed from their mother at birth and reared by an unrelated female. In general, the armpit effect seems to exist and to be beneficial to the species concerned because it lessens the chance of inbreeding.".
