Wealth inequality is a research topic typically reserved for humans. Now, research from the Max Planck Institute of Animal Behavior and the University of Nebraska-Lincoln suggests that studying wealth inequality in animals can help shed light on social evolution. Adapting approaches from the study of wealth inequality in humans, the researchers show how wealth—in the form of material goods, individual attributes, or social connections—occurs broadly across animal species and can be distributed equally or unequally. This framework offers the opportunity to unite different corners of evolutionary biology under the umbrella of wealth inequality, exploring the idea that the unequal distribution of value, whatever form that value may take, has important consequences for animal societies.
