aesthetics, philosophical discipline aimed perceptions, meaning, beauty (in nature or art), tends to define beauty as opposed to the useful (or functional). However, in nature where we all come, beauty is (almost or later) documentation useful and functional!
Since beauty is "the characteristic of a thing through a sensory experience (perception) provides a feeling of pleasure, a feeling of satisfaction or attraction," and that these feelings of pleasure and satisfaction s accompanying physiological reactions that have positive effects on health, beauty has already proved useful. It has also been shown that emotions in their vast majority had the same beneficial effects for health and longevity.
Better yet, the beautiful has a feeling of attraction, ie a seduction.
Scores of scientific studies have attempted to identify the ins and outs of the process of seduction.
In the animal kingdom, it was determined that the odors (pheromones) are used to indicate the availability of females ready to be mated to potential partners may be located more than ten kilometers. The importance of odors is also established, including those made by the immune MHC genes that give each a personal signature scent. According to a test with T-shirts worn by two nights in a row for men, women prefer those with genes and therefore their different smells. In his detailed analysis of animal behavior, biologist Thierry Lode emphasizes the role of the kiss. The exchange of saliva would initiate an exploration of the immune system (MHC) promoting the attractiveness of genetically different partners. The biologist also reveals the role of eccentric characters in the seduction. These exaggerated features, very present in animals such as the peacock's tail, result from an evolutionary trend in the exuberance and these "supernormal stimuli" cause a runaway desire. According to Thierry Lode, This same trend illustrated some artists like Fernando Botero, highlights the elements of identity between beauty, aesthetics and seduction. Finally, according to the same author, seduction, defined from biological characters still puts out the immune system of sexual partners: it is attracted to symmetrical features. Indeed, the fundamental bilateral symmetry of the body is altered by growth accidents often caused by disease, indicating the weakening of the immune system. Preferring sex partners to symmetrical features, the animal chooses a partner with an immune system transmitted to offspring and free from diseases. Other studies (including those conducted by David Buss) show that women place great importance on the financial perspectives of the man and his social status, in other words a comfort for them and their offspring, while men focus on their, age and physical beauty, fertility monitors, so a more descendants and in better health.
All these processes of seduction, attraction by the beautiful and involved in choosing the best partner, then in the evolution of species and therefore in a better adaptation to the environment, assurance of survival.
Beauty is not opposed to the functional, helpful, it is only a manifestation that occurs in the seduction, the survival of the species!
