Human Selection Is A Form Of Courtship Or Sexual Selection
Courtship, or sexual selection is a form of natural selection in which a male organism tries to prove his worth to the female organism of the same species. Males do this because they are they must pass on their genes to be successful, and females are looking for strong attractive males. Females need to be courted because they want to find a strong suitable male to pass genes onto their children. The courting is different in each species but ultimately females are trying to choose the best possible mate. The relationship between courtship and rape is that both ways of insemination are ideal to male organisms passing on their genes. Scorpionflies males use two unique strategies for mating. The first, they will bring females nuptial gifts to

    I believe the author is simply joking when the author call scorpions “pleasant, unassuming creatures with, on the whole, the most charming habits.” The tone of the sentence seem to be taken as a humorous statement, and not to be taken serious.…

    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.…

    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.…

    Natural selection may have been influential when it came to human choices and behaviors in a prehistoric society in that the natural selection process shaping the choices and behaviors of a human. Natural selection gives reward to the individuals that are more adaptive to their own environments in their achievements in the survival and reproductive realm. In fact, all humans belong to the same species. Humans have the possibility to interbreed with each other in nature to produce fertile offspring. This operates at certain gene levels, particular DNA sections that are encoded for proteins to serve as the software for a human 's choices and behaviors in life.…

    It has been identified that natural selection is based on selection of behaviours that enable genes to survive and evolve, such as cooking, and sexual selection is based on selection of genes that enable the attraction of mates such as humour. However it is still important to raise the issue of how much genes contribute to behaviours that are seen as being learnt through social interaction and how sexual selection takes into account those individuals who do not reproduce therefore preventing their gene…

    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…

    Darwin and Freud both evaluated the connection between biological traits and inheritance as expressed through social constructs, such as sexual impulses and desire. This theory manifests itself by examining human biology, neurology, evolution and applying it to expressed behavioural traits. A fundamental and intrinsic element of human behaviour stems from evolutionary adaptations in which basic desires are adapted through the recognition of success from earlier generations. Through this evolution, both Darwin and Freud placed an enormous emphasis on an individual’s desire for survival, the ultimate goal being self-preservation. Darwin and Freud’s theories converge at the point of primal and instinctive behaviour.…

    Such risk taking is said to enhance the social status of young men and make them more attractive sexual partners. Males were chosen to traits that relate to dominance and social status and have some involvement of indirect resources such as food and protection of the offspring which increase with education and socio economic status, whereas females have traits that contribute to signaling reproductive value and potential nurturance toward their offspring (Kenrick, Sadalla, Groth, & Trost,…
