Models Of Sexual Selection

Superior Essays
Sexual selection refers to a natural selection process, which arises through preference by one sex for specific characteristics in the member or members of the other sex. The purpose of this paper is to complete and present the requirements of the assignment on the Evolution Biology. The paper covers the issues that pertain to sexual selection such as the theoretical background as well as the evidence for models of mate choice. Furthermore, the writer covers the aspects of game theory and animal conflict as well as sexual conflict, which exists in the process of sexual selection. In addition, the paper covers the issues of ecological factors, which influence the animal mating systems as well as the male or female polymorphisms. All these are …show more content…
This refers to an evolutionary process through which selection occurs by a female chooser to a male chooser. The process of selection regards the attractiveness of the male’s phenotypic traits. Five models have been developed in order to explain the evolution of mate choice. However, for covering this assignment, the Indicator Traits will be highlighted and analyzed. The Indicator Traits suggests that the model of natural selection depends on the identification of specific traits. In this case, the indicator traits are traits that signal a good quality of an individual. Indicator traits are perceived as attractive traits, which indicate a wide genetic quality thus favoring the selection of on member of a particular sex over the other. During the selection process, often the female member of a species desires the specific traits to evolve among her offspring’s. Therefore, the choosy sex believes that by mating with a member of the opposite sex who holds the indicator traits, these genetic benefits will be passed over thus resulting in a high quality offspring (Kokko 2003). The hypothesis of the indicator traits is further divided into three key subtopics, which further explain the rationale behind the indicator traits. The subtopics include the good genes hypothesis, the Hamilton-Zuk hypothesis, and the good genes hypothesis. In selection, the choosy sex always wants the best genes to be transferred to the …show more content…
John Maynard Smith together with George R Price who formalized the analysis of evolutionary strategies developed the EGT. The game theory utilizes a mathematical criterion in order to predict the prevalent results of different strategies. Indeed, the sexual selection process involves strategies, which are often competing strategies (DeDeo, Krakauer, and Flack 2010). Therefore, specific strategies are found within specific environments or populations. For example, the men in Australia will apply specific competing strategies, which are common within their population as compared to men in Africa. The population aspect is quite important in explaining the issues revolving around evolution. The classical game theory is a significant model, which was developed by John Von Neumann explaining the optimal strategies within situations in competition between competing parties. In this case, the term contest refers to a situation with a high number of players who can make different moves in the

    Sexual selection, is a type of natural selection that operates on only one sex within a species. It is the result of competition for mates. (Textbook) By engaging in infanticide, the male primates are improving their opportunities to reproduce by eliminating dependent offspring of a future mate. Therefore, they are reducing the competition for mates and improving their own reproductive fitness.…

    Large body size in females can increase their number of eggs, therefore increasing their fecundity (John-Alder et al. 2007). Species that select for a trait pertaining to a higher number of offspring should favor females of larger size. On the other hand, large body size in males can increase their access to potential mates, leading to higher reproductive success (Cox et al. 2003, 2007). Species that select for a trait to aid in an organism’s ability to obtain a mate should favor larger size in males.…

    Chapter 5 explains how we are influenced by human nature and culture diversity, the likeness and differences between males and females. Additionally, the book also discusses the connections between evolution and gender, and the influence of our culture. Biological factors that are thought to shape gender differences include hormones and lateralization of brain function. Hormones may organize a biological predisposition to be masculine or feminine during the prenatal period, and the increase in hormones during puberty may activate that predisposition. In addition, social experiences may alter the levels of hormones, such as testosterone.…

    In the period from 1860-1900, Darwin developed his theory of natural selection. Natural selection was the idea that a dominant species would overcome all the rest. This sparked many ideas and philosophies, such as a weakening in the church, the rise of Social Darwinism, and a surge of new ideas and thought. The church had always been the lead in the sciences of the day, but when scientists started to challenge the church, their strength began to falter.…

    a. A reader would expect that the sexual selection would only be improved based on the increase in “intellectual powers”, but in reality, the increase in intellect causes us to be less favorable in sexual selection. As humans, the species would like the believe that we have progress in both intellect and sexual selection, but Darwin asserts that the two work in conjunction with each other. a. A reader with an understanding of rudimentary biology would know this to be true. The reason that this passage is interesting is that most of the modified traits do not get passed down. The picture challenges our expectations of how a difference in a characteristic can lead to a death in the individual of a species.…

    In this lab, we studied the emergence of anisogamy. We did so, by trying to understand how to major factors affect the size of gametes. These factors were: difficulty-of-movement and aging-fitness loss. Gametes are an incredibly important area to study and understand because it helps us identify gender in species as well as understand the mating interactions of males and females. As Dawkins explains in chapter nine of his book The Selfish Gene, size of gametes has a huge effect on how much investment a parent will put into their offspring.…

    There were many studies that were presented in the introduction of this article which contained 19 citations. A cross-fostering study was performed on animals and mammals, and results showed that adults prefer their mates to resemble their opposite sex parents, also called homogamy. As per the study, children observed their opposite-sex parent and prepare a mental template phenotypically, that fits their potential mate (Bereczkei, Gyuris, & Weisfeld, 2004, p. 1130). III.…

    Writing Assignment #1 Lasiognathus dinema There are a couple misconceptions you might have about evolution and natural selection. The strongest and most important organisms do not survive over the generations. Although evolution occurs due to fitness in an individual or individuals of a species, an organism cannot survive over generations. Fitness is achieved through variations in populations of species through genetic differentiation (Scottville “n.d.”). Since the life cycle of all living organisms is to be born, survive, mate, and die, it is impossible for an organism to live through several generations.…

    Genetically, in terms of heredity, the black ants will reproduce and pass on the stronger traits. In our text, Jurmain(2013) describes selective pressures as “Forces in the environment that influence reproductive success in individuals” (page 41). Many organisms experience these selective pressures due to climate change and are aggressively seeking adaptive qualities to survive. For instance, the genetic make up of individual organisms, or their genotypes, plays a crucial role when climate change forces adaptation. According to Godfrey-Smith (2009) “These formulations are usually interpreted as saying that whenever we have variation, heritability, and fitness differences with respect to a particular trait in a population, change in that trait will ensue” (page 20).…

    Stephanie Okolo BIO 119-001 18 April 2016 How female choice governs sexual selection. Sexual selection is perhaps one of the most intriguing phenomena in the mammalian kingdom. It is the functional relationship between phenotypes and fitness that enables successful genes of parents to be passed down to their progeny. One important mechanism of sexual selection is how we have evolved to have complete autonomy with whom we reproduce with, especially how that choice relies heavily with females.…
