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…
Relationships can be explained by both sexual selection and the human reproductive system; however they both differ from each other. Sexual selection explains how evolution is driven by competitions for mating and to ensure the characteristics that are chose allow the reproduction to be a success. The human reproductive behaviour explains the strategies that both males and females take on. Sexual selection has two types, Intra-sexual selection and Inter- sexual selection. Intra-sexual selection is men competing towards each other for females. This allowed men to evolve into bigger, stronger males with more manly characteristics. Inter-sexual selection involves females choosing their males. They seek partners who can provide them with resources such as a home and wealth as well as protection. Due to the two types of selection, both male and females have evolved leading to better characteristics.…
There are many theories that try to explain relationships between sexual selection and human reproductive behaviour. Evolutionary theory is one such theory.…
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.…

In “Monogamy vs. Promiscuity: Putting Evolutionary Psychology on the Couch”, Natalie Angier brings forward the topic in regards to male female sex/mate choice distinctions in the field known as Evolutionary Psychology. Evolutionary psychology is what Angier calls to be a “cranky and despotic Cyclops, its single eye glaring through an overwhelmingly masculinist lens” (505). The reason why she sees their view as masculinist is due to the fact that the view of the behavior of males is as narrow as their view of women. She claims that the way the Evolutionary Psychologists see women and their ideas of…
Nowadays, casual hookups change the way people interact and communicate, which become the popular cultural change throughout the Westernized world. Taken together, Garcia, Reiber, Massey, and Merriwether (2012) discussed different approaches of viewing the topic of sexual hookup culture, whereas Vrangalova and Ong (2014) examined the moderating effect of sociosexuality on four indicators of psychological well-beings and casual sex. Although evolutionary theory explains why hookups are beneficial and valuable to individual, I believe socialization and cultural factor play the most significant role in shaping individual’s behaviors and motivations in casual sex regardless of individual and sex differences.…
1. One way evolutionary psychology can answer Dylan’s promiscuity is that it has become a learned behavior that he has never had to correct/change. The study states that he has been promiscuous since high school and he sees no reason to change his ways.…
A new idea is never accepted easily; when an idea first comes into existence many questions are raised before the notion convinces anyone. Along with a new theory comes many new controversies and critiques which go against the bright new idea. An example of a brilliant idea which still has many controversies surrounding it is the notion of evolutionary psychology. As this field progresses into the world, many brilliant scientists from around the world reason why they think it’s false. Both supporters and adversaries not only helped shed light for each other, but also helped shed light in helping me decide whether I wanted to stand behind this new field, or be among the many that decline it.…
The importance of early infant attachment cannot be overstated. It is at the heart of healthy child development and lays the foundation for relating intimately with others, including spouses and children. It affects parents' abilities to nurture and to be responsive to their children. The effects of infant attachment are long-term, influencing generations of families.…
Evolution, in its most simple sense, is described as change over time. I believe it’s important that we understand how evolutionary thinking is relevant to understanding disease as an agent of natural selection because evolutionary thinking taps into two important fields: biology and medicine. It helps us understand the field of biology because evolution helps explain life; specifically differences, changes and developments to adapt. On the other hand, it helps us understand the field of medicine as it will allow researchers and scientists to conduct experiments to come up with new therapies, drugs or treatments to tackle diseases. By excluding evolution into the conversation, it deprives us from understanding fundamental concept of what…
