Abstract
Marcondes and Douvas (2024) provide a macroscale insight into the evolution of mating systems in birds. The study shows that resource-defense polygamous lineages are evolutionarily unstable, commonly transitioning into monogamy or going extinct. Surprisingly, lek polygamy is as evolutionary stable as monogamy. While in monogamy both sexes benefit from cooperative behaviour by equally investing in parental care, in lekking systems each sex maximizes their fitness independently: females invest in parental care and males enhance sexually selected traits.
期刊介绍：
Evolution, published for the Society for the Study of Evolution, is the premier publication devoted to the study of organic evolution and the integration of the various fields of science concerned with evolution. The journal presents significant and original results that extend our understanding of evolutionary phenomena and processes.
