Sexual selection

Natural Selection and Sexual Selection This world is colored by diverse species. Some of them persist but others distinct. It is natural and sexual selections that result in incredible difference. Both are leading to a process of evolution while there still exist differences between two selections. “In mammalian males, sexual selection can have a great effect on behavior and morphology than other forms of natural selection because male reproductive success usually varies much more than female reproductive success” says in Boyd and Silk’s book (2015, p.158). Charles Darwin’s theory has played an important role in both natural selection and sexual selection. Body and Silk (2015, p.5-6) mentioned: “Darwin’s theory of adaptation follows from three…

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…

earth, organisms are thought to have developed and diversified in a process called evolution. Evolution occurs through five factors; gene flow, genetic drift, mutations, natural selection and sexual selection. Each factor changes allele frequencies within a population leading to speciation, the evolution of a population into a distinct species. Gene flow transfers genes from one population to another, such as migration. Genetic drift is seen in small populations where a specific allele is either…

Furthermore, in order to have a better understanding of how Sexual Selection affects behaviors in both humans and animals, it is important to know what Sexual Selection is. According to the Oxford Dictionary, Sexual Selection by definition is “Natural selection arising through preference by one sex for certain characteristics in individuals of the other sex”. The existence of it has aged back since the dawn of life, but it was not studied until Charles Darwin proposed his book The Origin of…

In Jones short selection of “The Decent of Men”, he is taking Darwin’s theories about “Of Sexual Selection and Natural Selection” and I would say updating them and not creating something altogether new. The difference that I see is that Jones has new information to add because so much time has passed since Darwin wrote his book. We have learned that the population of men is descending, or is not as favorable as it once was by pure observation. Jones takes Darwin’s idea of the battle of men…

generation to generation. Sexual selection is an important subject which sometimes creates many diversities. After reading the article, I can agree that sexual selection plays a very important role in the development of the human mind. Through generations, all living things came to sexual selection as the way out of obtaining an attractive and intelligent (in human cases) offspring. For the most part we expect to be able to explain most of the characteristics of an organism as adaptations; that…

understand this behavior, we can take a look at different explanations which shape human mating behavior. Researching this topic we can find evolutionary perspectives, which delve into topics, such as parental investment, survival, and sexual selection. There is also an opposition to these evolutionary ideas which suggest that evolution may not have to do much with our mating behavior, but is influenced but social norms and libidinous desires. This paper will try to look into these ideas and try…

Hall – based on data collected through his three studies, realized that humor and intelligent do not contact with any mutual direct, but "the more attempts at humor a male made and the more of those attempts a female laughed at, the more interested in dating the female was” (Jeffrey,…

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. The captious…

Dickson 44760191 Target Article Puts, DA, Jones, BC and DeBruine, LM. 2012. Sexual selection on human faces and voices. Journal of Sex Research, 49(2–3), 227–243. This article argues that the sexually dimorphic traits of vocal cords and facial structure in humans evolved due to sexual selection. The authors focus on two main arguments; that female mate choice and competition between males shaped both of these characteristics, particularly in men. Researchers used past evidence to show that…
