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).

(Dunbar, 1983) Among mountain gorillas, half of all the groups are one male. However, females leave from one group to another. “Polygynous females might be compensated for loss of exclusive paternal care by mating with a genetically superior male, thereby increasing the likelihood of their progeny’s survival and ability to produce offspring (Alatalo and Lundberg 1986).” (Hoglund, J. 1995) The competition for these mating opportunities is driven by the female’s choice. When this occurs, the males lose females to another one male group and it exploits what males mating opportunities.

Natural selection is the process in which heritable traits that make it more likely for organisms to survive and successfully reproduce become more common in a population over successive generations. Each of us individuals is specifically shaped and formed by our own genetic pattern. We inherit this pattern half from are mother and half from are father. The cause of this is the proximate cause that led it’s phenotype to ultimate causes. Much of we know today about evolution derives from the late great pioneer, Charles Darwin. Charles Darwin was an english naturalist that even from an early age was very interested in outdoor pursuits. Early in his prep career his father tried sending him to the University of Edinburg to pursue his medical

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

Albeit, the sexual selection theory is presumed force of natural selection causing individuals to develop reproductive strategies which maximize the like hood of their producing the fittest possible offspring. Otherwise, suggested a competition between males and competition for females as the two most likely mechanism of sexual selection theory.

Thus, her breeding span is limited (79). In contrast, for males, it is minimal. He simply must produce sperm cells and go through with an act of copulation, in effect, his reproductive capability is limited by the number of females he mates with (Contrary to popular belief, humans are not a monogamous species but a largely monogamous and partly polgynous species) (Gray 79& 83). In addition, males must play the aggressor role in relationships and are more attracted to physical stimuli (Kanin pg. 71). These all require that males recognize love much more quicker then females (Kanin pg. 71).

In the article the researchers were trying to challenge the sexual strategies theory. It seems as though sexual strategies theory is different genders having different preferences when choosing a mate, in the case of long and short term relationships. The hypothesis at first was that both boys and girls felt that attractiveness was important. Girls would be more inclined to date someone because of social status and that boys would be the complete opposite. They also expected that social status would only become important when the person is attractive and social status would be important no matter if the person is attractive on no for girls. The last thing that was tested was according to Ha (2009) “the potential moderator effects of

The majority of the time the person who is left longing for more than just a casual hookup is the female. Women, by nature, are more likely to become more emotionally attached, especially when it comes to sexual activities. However, most of the time, girls will be willing to play along with the game of hooking up. Perhaps, in hopes, that it will someday lead to something more. But, if and when it doesn’t, they can be left emotionally distraught. Girls will become attached to the person they are with and grow to have a sincere care for them. However, when it comes to picking a mate, boys are not as particular about the girl. A study, Age and gender differences in mate selection criteria for various involvement levels found that “men should be equally as selective as women with respect to long-term mates, but less selective than woman with respect to short-term mates criteria (Kenrick).” Boys are less likely to think about all aspects of girl when planning on hooking up with her, unlike girls. They are not as particular because they are just looking for

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 is combat. Males of the same species battle for the female’s attention and, in turn, get to mate with her and produce offspring. The second is display. Display is important since the ornate male features are used to attract females. The female animal sees the male ornaments to be an indication of the male’s vitality (Brown 1-6). The suggestion is that the bigger, more colorful males have proved themselves to be of better quality and thus the female will be more attracted to them. The male who is small and not as colorful will probably not produce nearly as many offspring as the male who is big and bright. Females want high quality males so that they can produce high quality offspring (Zahavi

Sexual selection can best be described by the definition given by Darwin himself. Sexual selection is “the advantage which certain individuals have over other individuals of the same species solely in respect of reproduction” (Hosken et al, 2011). Sexual selection occurs throughout the animal kingdom, where male frogs dominate through the depth of their croak, and certain peacocks reign superior based on the colour and intricate detail on their tails. They remain superior to their lesser counterparts as they bear more admirable characteristics, from which they are chosen by females of the same species.

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

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
