Procreation and mating selection are linked to the primal desire of survival and genetic continuity. The means of creating successful offspring are often paved through distinctive selection, which are often tailored to specific genetic traits that one or more partners possess. These concepts are a biological component that drives humans to reproduce with specific individuals. Since humans are unable to procreate by asexual means, the selection of a mate and their genetic information are highly important in concepts of reproduction. Males and females alike are psychologically and physically wired to make mating choice based on concepts of physical presentation and characteristics. These components often link together couples for mating purposes, …show more content…
Both men and women establish hair in their connection with sexual selection due to its biological link to fertility. For women, healthy vibrant hair is connected to health, it serves as a fertility indicator. If a woman has healthy hair, she herself must be healthy and vibrant. Therefore, her health is tailored to her ability to reproduce. Health is a component in the reproduction of offspring. If a parent is healthy, then an offspring will have the opportunity to be healthy. According to David Buss, professor of psychology at the University of Texas, in his book Human Mating Strategies, “the speed of hair plays a role in the evolution of what women want, namely those characteristics that reliably led to an increase women’s reproductive success. Hair is one of these characteristics” (50). These concepts are smart in the overall development of reproductive capabilities. If the physical appearance of hair is connected to fertility and the ultimate goal of humans is to reproduce successful offspring. Hair growth is related to testosterone, or the male growth hormone, is correlated toward dominance. Amounts of testosterone are related to protection and sexual drive, a mechanism that is valued in the protection and survival of a woman and her offspring. These are also relevant to a specific smell that radiates in …show more content…
This has always been a present factor due to its capability to foresee danger, such as a fire or unpleasant smell. Since humans tend to avoid disturbing smells to survive, this biological mechanism has also been shown to translate with human selection. This biological component is tailored to pheromones, or chemicals that the body produces. These pheromones are used to attract the attention of a mate. An article titled Human Pheromones: The Science Behind the Scent of Attraction states that “pheromones signal reproductive quality when excreted by various regions such as skin, sweat glands and urine and furthermore only about 10 percent of men give off a specific pheromone – androsterone – which is the so called sex-appeal” (“Human Pheromones”) Humans produce sweat in places that produce a lot of hair. While this mechanism is used to keep the body from over-heating, the sweat also comes into contact with the hair in each area. Sweat and the hair produce a specific scent that others around you may pick up on, and depending on the individual, this scent may be pleasant or fowl. Woman tend to prefer a musky scent where men prefer a lighter scent. Each individual scent is tailored to a specific person, and generally the mate will find this smell pleasant and enjoy the biological components their partner creates. This concept is actually shown to be an immune system component where scent is used to
“Romantic love modulates women’s identification of men’s body odors.” is a scholarly article. This article is about women going to continuing loving their boyfriend’s when they identify their body odors. Romantic love is a powerful emotions towards couples. But, would this powerful love continue when women identify something they disagree about men’s. Would this bring women closer together with their boyfriends or would this drag them apart. So they tested out this theory by having women identify their boyfriend’s body odor, the same sex, and the opposite sex. The result in a positive and negative thing. Some couples have got closer together by having a strong romantic love for each other. The negative results is some women did not like the
In another study, Langlois and Roggaman (1990) took photos of faces and morphed them together to produce composite images made up of 4, 8, 16 or 32 images. Participants rated faces as increasingly attractive the more faces that went into each image; this applied to both male and female faces. The more faces in an image, the more symmetrical they become, it seems that moving a facial image closer to the average increases its perceived attractiveness. It is likely that symmetry equates to fitness and “good genes”, these people are less likely to have been affected by harmful mutation. People with attractive faces are preferred because of the benefits of passing on these attractive characteristics to offspring. Little & Hancock propose that humans have evolved to be attracted to symmetrical faces because they indicate “averageness”, which equates to genetic health. Grammar and Thornhill (1994) found that females are attracted to males with masculine characteristics, for example: large jaw and prominent cheekbones. These features arise as a result of testosterone, which is also a handicap because it suppresses the immune system. Therefore, showing only “healthy” individuals can afford to produce these traits- advertising a strong immune system. Cartwright (2000) supported this, finding men prefer photographs of women with symmetrical faces and vice versa.
This essay aims to show a comparison between the differences between both female short-term mating strategies and female long-term mating strategies. It will explore the evolution of psychology that has shown reasons for human mating and how these reasons go above and beyond the general idea of physical attractiveness and love. This essay will identify how mate preferences have evolved and further identify psychological mechanisms that women have used to select their mates over the past. This essay will compare and critically discuss the differences and outline them between female short-term mating strategies and female long-term mating
In his article, The Strategies of Finding a Mate, David M. Buss discusses the act of finding a mate and the characteristics that people are drawn to in a mate. He begins the article with a brief look at the history of mating and the theories that have previously been proposed. In particular he addressed Charles Darwin’s theory of sexual evolution and belief in preferential mate choice. Buss proposes that there are three components to human mating. He states that “human mating is inherently strategic… mating strategies are context-dependent… [and that] men and women have faced different mating problems over the course of human evolution and, as a consequence, have evolved different strategies” (Buss, 1994, p. 241). He uses this theory to propose nine different hypotheses to prove that despite humans being varied and different from each other, all humans look for similar characteristics when trying to find a mate (Buss, 1994).
In this chapter, Orr and Zuk explains the importance of ornaments of males and the mechanism behind sexual selection. The questions that they seek to answer involve the fact that why are the males fighting during mating season, and the ones with the colorful ornaments. In both human and animal relationship, there are many similarities, such as the fact that the male fights for the female such as their masculinity or traits that females look for whether an animal or a human. Darwin in The Origin explained that sexual selection involves competition, but for mating instead of fighting for survival, in The Descent went on to explain the relevance of the traits like the peacock tails.
Annotated Bibliography- Pheromones Doty, Richard L. “Neurobiology of Chemical Communication.” Human Pheromones, 2014. Richard Doty is the director of the University of Peninsula Smell and Taste Center starting in 1980. Doty describes pheromones as substances which are secreted to the outside by an individual of the same species, in which they release a specific reaction for example, a definite behavior or a developmental process. Scientists while looking at insects see that they release pheromones that send signals regarding mating, food, and warning signs but are unsure when comparing this to humans.
Therefore, mate choice is extremely important for individuals to avoid mating with the wrong species but it also operates within a species as well. This tendency to avoid heterospecific mates is called behavioral isolation. Mate choice can be important in the evolutionary process, speciation, in which populations of conspecific diverge into separate species (Ecology and Evolution Behavior Lab Packet).
Males and females differ considerably in how much they each invest in order to make offspring and a result of this, they approach mating with different methods. Researchers and scientists learn and examine these varying mating systems to explain how males and females pair up. A mating system explains the techniques males and females use to pair up when selecting a mate. It is important to begin by reviewing and understanding the reproductive strategies among primates. The major types of mating systems found in primates are monogamy and polygamy. Monogamy is a practice of mating in which one male pairs with one female. Polygamy also known as bisexual, is a pattern of mating in which a male mates with more than one female and a female mates with more than one male (Wong , 2010). Polygamy is then clarified into polygyny and polyandry. Polygyny is when one male mates with multiple females. Polyandry is when one female mates with multiple males. Recognizing the diversity of mating systems will help in understanding the interactive relationship of sexual size dimorphism and behavior in primates.
The first few chapters discuss in depth both the general rules for mate selection and the differences in mate selection and varying preferences for male and female genders. As explained in the intro the author theorizes that the current behavior of humans in relation to mating behavior can be linked to our evolutionary past. He references Charles Darwin 's theory of evolution and his idea of natural selection, which is the the process through which organisms adapt to their environment and in doing so tend to
Sexual selection is categorized in to two categories; intersexual selection and intrasexual competition. Intersexual selection is also known as mate choice or female choice in which males competes with fellow males for female. This means that the male must develop a feature that would attract the opposite sex; sometimes this can lead to fashion. The conditions determining which factor becomes more limited can be explained by the way of Bateman’s Principle which states that the sex which invest most in producing off springs becomes a limited over which the other sex will fight for. Intrasexual competition is also known as male-male competition where by members of the less
Biologists believed that facial symmetry should be attractive because it may signal mate quality. Rhodes, Proffit, Grady and Sumich (1998) manipulated the symmetry to figure out the effect on attractiveness. 4 versions of a picture were created. One was perfectly symmetric, the others were a highly symmetric version, normal level of symmetry and a low symmetric version.64 subjects rated these faces. The results clearly stated that perfect symmetry was significantly more attractive and low symmetry faces were unattractive, more over the males found the perfect symmetric faces more appealing as potential life partners, so facial symmetry does play a role in mate selection. In the second experiment the authors compared the attractiveness of faces at three symmetry levels. These were normal, high and perfect. The subjects were shown two versions of the same face at different
There are a variety of different mating strategies among different male dolphins species. “Male mating strategies and forms of competitive interaction among male cetaceans lead to the development of sexually dimorphic features such as prominent postanal humps, reproductive adaptation such as large testis size, and retained bodily scarring caused by interactions with conspecifics.” (Murphy, 2005) Cetacean have been noted to either have a polygynous or polygynandrous mating system. (Murphy, 2005) These mating systems have led to a number of different types of competition among males such as contest competition (where males limit the access of other males to females by aggressive displays or fights) scramble competition (competition to disperse and find sexually receptive females), endurance-rivalry competition (competition to remain sexually active over a longer period of time), mate-choice competition (competition in courtship), and sperm competition (competition between the sperm of 2 or more males).” (Murphy, 2005) Individual males will use these different strategies depending on their dominance in rank, size, age , and number and quality of reproductive females. (Murphy, 2005) Contest competition and courtship competition have been documented in polygynous species such as bottlenose dolphin (tursiops truncates), and humpback whales.( Murphy, 2005) “Sexual dimorphism in size, weaponry (teeth and husks), and
In addition, an experiment by McClintock showed that women were attracted to the smell of a man who was genetically similar, but not too similar, to their fathers ((1)). Therefore, our genetic information might play a role in whether or not someone is desirable in order to avoid inbreeding or, on the other end of the spectrum, to avoid the loss of desirable gene combinations. Inevitably, however, it is our brain that processes another individual's appearance, lifestyle, how they relate to past individuals we have met, and, possibly, their pheromones. Then, based on this information, we decide, within our brain, whether or not this person is worth getting to know.
Another evolutionary explanation of gender development is mate choice, which suggests that gender role behaviours are related to reproductive strategies. It is thought that men will look for women who are young whereas women are usually more interested in the resources of a mate. This can be explained from an evolutionary perspective as mating with a physically attractive woman
Despite the problems our senses may cause, they still play a significant role in our areas of knowledge. Evolutionarily, we trusted our sense. According to Charles Darwin’s natural selection theory, the strongest will survive and the weakest will die. Men select the best looking women and women select the strongest looking man. Although the this pattern has now changed, men are still generally attracted to good looking women and women choose men that they feel being safe with. Scientifically, scientists need to observe the phenomenon and conduct
