14. What is generally the most important factor in the evolution of mating systems and why does this “make sense’?…
However, a weakness of May and Hamilton’s study is that the study lacks ecological validity. It was conducted in lab settings using artificial tasks such as rating photos whilst listening to music which is clearly not a realistic method of judging an individual’s attractiveness. Also replicating a natural social environment may be impossible. This…
One theory is ‘The Matching Hypothesis’ which is a social psychological theory based on relationships, proposed by Goffman in 1952. It suggests that in order for a relationship to be a long and successful one; both partners in the relationship must be equally matched in attractiveness. The reason for this is due to fear of rejection, therefore when searching for a potential life partner the primary drive is to select someone who is similarly attractive.…
Hendrix's argument has one warrant: The assumption that all human beings are in search of a mate. He prepares for rebuttal by mentioning several counterarguments including the passionate emotional dissatisfaction experienced during a breakup as well as the continual habit of choosing mates that are remarkably similar to previous mates.…
Sexual selection can be used to explain certain characteristics or behaviours which increase an individual’s reproductive success. These characteristics may get exaggerated over evolutionary time. In humans, these characteristics may include good physical and mental health, as well as physical features such as good looks etc. these characteristics are attractive because they show an ability to reproduce and pass on these genes to offspring. There are two types of sexual selection, intrasexual and intersexual. Intrasexual selection is the evolution of characteristics that enable an individual to compete with their rivals whereas intersexual selection is the evolution of characteristics that are attractive to a mate. An example of this would be a peacock’s tail. The peacock with the ‘best’ tail (longest and brightest etc.) is considered to be more attractive to the peahen and therefore he is more likely to reproduce and pass on his genes to the next generation. Buss, 1989, found evidence to support this. Over 10000 participants across 37 different cultures took part in his study on differences in intersexual selection. Questionnaires were given to the participants, asking about preferences for variables such as marriage, age differences, characteristics etc. He found that women valued qualities such as ambition and industriousness in men – qualities showing their financial potential. He also found that men valued youth and physical attractiveness more highly than women. This suggests that males look for qualities associated with fertility in line with evolutionary predictions. He concluded that women have evolved to select mates who can provide resources for themselves and their offspring. Buss’ study had over 10000 participants and therefore has credibility, however the participants may have not given a truthful answer and instead given one they thought would appear more…
Evolutionary theory states that all animals are motivated by the desire to ensure that their genes make it into the gene pool of the next generation. Natural selection is the tendency of individuals best adapted to their environment to survive and pass on their genes. Sexual selection is the probability of passing on our genes depends partly on any chances of survival but also on ability to attract a mate. Those who have genes for features which make them attractive are most likely to reproduce and pass all their genes on. This could be supported by Darwin’s suggestion that the peacock’s bright colouring was there to attract the peahen. Sexual selection is important for us as humans as some physical characteristics may not have developed to increase our survival rate, but simply to make us more sexually desirable. An example of this is eye/hair colour and distribution of muscle. Our sexual behaviour can be influenced genes, and this is similar no matter what culture you come from. They are also similar in terms of physical characteristics. This is a significant factor because it is a demonstration of the universal…
The nature of sexual selection is derived from the evolutionary theory. This suggests that the people who we choose to have sex with has been born into us and is an innate response we have. It also suggests that all behaviours are adaptive, including relationship formation, therefore forming a relationship should help out ‘survival’ in the way of passing on our genes.…
Homogamy: The tendency to choose a mate whose personal or group characteristics differ from our own. Choices in mate selection that can be limited by societies encouragement of homogamy.(Also called positive assortion mating).…
Angier explores the cardinal premises of evolutionary psychology. Examples of these cardinal premises are 1. Men are more promiscuous and less sexually reserved than women are. 2. Women are inherently more interested in a stable relationship than men are. 3. Women are naturally attracted to high-status men with resources. 4. Men are naturally attracted to youth and beauty. 5. Humankind's core preferences and desires were hammered out. She goes into great depth in exploring these principles and tells us that a lot of these socially constructed values don't go away…
-Mate selection is seen as being too important a decision to be left up to inexperienced young people, especially if they have had little contact with members of the opposite gender.…
In the wild mating in the group is supposed to be reserved for the alpha male and alpha female, but things happen to change this. First the alpha male might die or be overthrown by another male from inside their group or another group. Also, the alpha female might mate with a wandering male from another group while out foraging for food, the alpha male never knowing. What they won't do is mate with another direct family member. When the dominate female is ready to breed she will chase away all the other beta families that can bear children, this will be females at 10 months and older. The temporary outcast will follow the gang until the alpha female has had her pups (babies) and regains her strength. This is done because she wants only her offspring in the group and another beta female might try and displace her during her weakened time of giving birth. The trailing females often get impregnated from males from other groups they encounter. Often they will abort these births. If they do give birth they will attempt to sneak them in with the pups of the alpha female. The alpha female will, if she notices, kill and eat the beta female babies. If the alpha female pup dies, no other meerkat will eat them. A few days after the birth of the alpha’s pups, the once…
When looking at mate selection, I agree with Dr. Helen Fisher’s findings that attraction is one of the primary factors in mate selection (DNews, 2014). There is a reason that two complete strangers can come together in a room and end up intimate with each other whereas two other strangers can come together in a room and never see one other again. The video showed the chemical reaction we encounter during courtship (DNews, 2014), something our brains have been doing this since the dawn of mankind. When a person is looking for a mate they will encounter several potential perspectives until they find that one specific person they’re attracted to over anyone else.…
For any evolution to gain some legacy, surviving is not enough without reproduction. In the world, over 90% of all the species have sexual reproduction. In this case, two individuals of a certain species from each sex have to mate so that they can produce offspring. Reproduction is seen as an expensive ordeal which has potential of exerting a considerable evolutionary pressure. This pressure was portrayed by Darwin as sexual selection operating through some members of a given species. In terms of mating, members of a given species may have an advantage over others in respect to mating hence resulting in a form of selection. The increase in the mating success…
The first theory that Hendrix describes is that of the biological theory, which means that women select men who are that of “alpha” qualities. They choose men who will provide for their future family or supply themselves with nourishment. Society makes men feel that they have all the weight on their shoulders and men are made to fulfill the manly duties. When I look for certain men, I choose men that have an attractive personality. Some people just choose the looks, but I focus more on the way he portrays himself in front of me and other people. My dating experience has been bumpy and slow these past years. I have only had one boyfriend and have learned nothing. As everyone always says that you always find your soul mate in college, I believe that to be true. As I have not found one yet, I still believe in that opinion. As I see everyone else going out with their boyfriends/girlfriends, it makes me feel sad. I was never much of a social person when it comes to meeting other people. Therefore, I do not agree with this theory because I believe that it is not all about choosing your mate on their physical traits, but more on their personality.…
There is no doubt that men and women are attracted to each other, which, according to the theory of evolution, is attributable to the human’s survival instinct. But to whom does this reciprocal attraction primarily apply, and are some individuals more attractive than others? In that case, what decides that? These rather intricate questions are treated and addressed in Peter Holley’s article “I have a dad bod. Here’s why women love it” from the 11th of May, 2015. In the article, Holley elucidates and clarifies women’s attraction to men, claiming that it exclusively and indubitably concerns men with dad bods, for which reason they are more desirable than men who are fit.…
