The peacock model is an inspiring theoretical framework that is widely used in a variety of fields, such as biology, economics, and social sciences. The core idea, derived from the display of feathers in peacocks, is that during evolution certain traits may not have been directly necessary for survival, but rather for acquiring a mate or increasing social status. This phenomenon is known as "sexual selection," and it challenges the traditional Darwinian theory of natural selection.

In ecosystems, the peacock model highlights the relationship between biodiversity and adaptation. Some species attract mates by evolving ornate features that do not necessarily help them survive in certain environments, but may actually increase their risk of predation. However, it is these traits that attract potential mates and give them a reproductive advantage. This phenomenon has prompted researchers to re-examine the diversity of adaptations in an attempt to uncover the complex balance between survival and reproduction.

In economics, the peacock model has also been extended accordingly. Products and services in the market often appeal to consumers through unique design, brand image or added value, not just based on functional needs. This phenomenon is particularly evident in the luxury industry, where consumers not only buy the product itself, but also seek social recognition and status symbols. Therefore, enterprises often need to take into account the psychological needs and social impact of consumers when formulating market strategies.

The peacock model can also be seen in the social sciences. In interpersonal communication and social networks, individuals win the attention and recognition of others by displaying their unique personalities, talents and resources. This kind of behavior is not only related to the embodiment of self-worth, but also affects the formation and development of social structure.
