Altruistic Behavior amongst Humans Altruism has been studied for many years, and will continue to be studied as well as grow in the years to come. The four selective forces of altruism is the reciprocity, phenotypic plasticity, kin selection, and inclusive fitness. The study that comes to mind for reciprocity is the study in our book about lobsters, and the different villages taking the risk in sharing information about potential gain. The thought of sharing with one’s people is more understandable rather than sharing with other villages that do not necessarily benefit your village in any way. It is more like an “I scratch your back, you scratch my back” type of idea. The thing that favors reciprocity the most is risk reduction. The phenotypic plasticity is a phenotype defined as some trait of an organism prescribed at least in part by its gene. The study conducted about the birds and their choice of a nesting tree comes to mind for this selective force. Allele a started off being the more dominant gene causing the bird to favor oak trees for nesting, and allele b preferred pine trees for nesting. The alleles are the genes that prescribed the tendency to choose oak or pine trees (Wilson). The way organism can change its phenotype in response to changes in the environment, is remarkable. For the allele a to go from being the more dominant trait to the less dominant trait compared to allele b and be able to make that adaption to its new environment is unsound. The phenotypic plasticity is altruistic because of the way they help each other make the adaption from one lifestyle to the next. The thing that favors phenotypic plasticity is adaptation. Kin selection is another selective force that favors altruism. The study that comes to mind for this particular force is also the “Cinderella Effect”, because biological parents are expected to treat
