![]() ![]() Įvolutionary psychology explanations for the existence of beards include signalling sexual maturity and signalling dominance by the increasing perceived size of jaws clean-shaved faces are rated less dominant than bearded. Modern biologists have reaffirmed the role of sexual selection in the evolution of beards, concluding that there is evidence that a majority of women find men with beards more attractive than men without beards. Charles Darwin first suggested a possible evolutionary explanation of beards in his work The Descent of Man, which hypothesized that the process of sexual selection may have led to beards. Evolution Different types of beards: 1) Incipient 2) Moustache 3) Goatee or Mandarin 4) Spanish-style 5) Long sideburns 6) Sideburns joined by a moustache 7) Style Van Dyke 8) Full beard.īiologists characterize beards as a secondary sexual characteristic because they are unique to one sex, yet do not play a direct role in reproduction. Dihydrotestosterone is produced from testosterone, the levels of which vary with season. Dihydrotestosterone also promotes balding. Beard growth is linked to stimulation of hair follicles in the area by dihydrotestosterone, which continues to affect beard growth after puberty. In countries with colder climates, beards help protect the wearer's face from the elements. In cultures where facial hair is uncommon (or currently out of fashion), beards may be associated with poor hygiene or an unconventional demeanor. Other cultures, even while not officially mandating it, view a beard as central to a man's virility, exemplifying such virtues as wisdom, strength, sexual prowess and high social status. Some religions (such as some sects of Islam, and Sikhism) have considered a full beard to be essential and mandate it as part of their observance. Throughout the course of history, societal attitudes toward male beards have varied widely depending on factors such as prevailing cultural-religious traditions and the current era's fashion trends. In humans, usually pubescent or adult males are able to start growing beards, on average at the age of 21. A beard is the hair that grows on the jaw, chin, upper lip, lower lip, cheeks, and neck of humans and some non-human animals.
