They follow “up” the concentration gradient of the pheromone, a path which leads them to the danger. Pheromones are also used in attracting a mate. These chemicals, called sex pheromones are released into the air, usually by the female, and are detected by males of the same species. The males follow in the direction from which the pheromone came leading them to the female. Snails also use pheromones to guide and mate with other snails.
Why is Sex Fun? by Jared Diamond Book Report In the book, Why is Sex Fun, Jared Diamond discusses the question, what were the lifestyle changes and inherited constraints that formed the evolution of weird sexuality? Weird sexuality is the comparison of human sexual habits to animals such as fish, monkeys, birds, and many others. The six main distinctions between humans and animals that Diamond addresses are marriage as a partnership for joint rearing of children, having sex with one partner, having sex in private, couples living in society among other couples with whom they cooperate economically and territorially with, concealment of human ovulation, and female menopause resulting in human copulations occurring at times unsuitable for conception. Diamond covers each one of these points in the chapters and relates them back to the evolution of our sexuality.
This is what is said to cause differences in gender identity. Research on animals has helped to give a better understanding on the effect of hormones on the INAH. Young (1966) had injected male hormones into female rats and vice versa during a critical stage in early development. He found that the mating positions for the rats had been reversed and that the male rats had adopted the ‘lordosis’ position, with the female rats attempting to mount the male from behind. It was said that the injections had effected the INAH and as a result different gender behaviour shad been shown.
Pheromones are also used in attracting a mate. These chemicals, called sex pheromones are released into the air, usually by the female, and are detected by males of the same species. The males follow in the direction from which the pheromone came leading them to the female. The sex pheromone released by the female gypsy moth can be detected by males at very low concentrations (one molecule of pheromone per 10 17 molecules of air), while the sex pheromone of the female silkworm moth can be detected from several miles away. Although pheromones released into the air are distributed over large areas and travel great distances, for some animals air-borne pheromones aren’t always an ideal means of communication.
Within “The Bloody Chamber” Carter demonstrates how her characters are a form of exploration into base human instincts but also explores the idea of their subconscious desires playing a major part in the development of the story. Subconscious desires are the desires of the characters they often don’t voice; in Carter’s tale these are heavily sexual. On the other hand much of Carter’s tale is a reflection of basic human nature and instinct and how that can affect the way men and women interact. The concept of Carter exploring base instincts within “The Bloody Chamber” is mainly apparent through her use of language to describe her main characters. The Marquis’ description is particularly animalistic; Carter uses phrases like “(his) dark mane” to describe his hair.
Nurture on the other hand is a view, is a view proposed by the social approach suggesting that behavior is affected by socialization and environment. The natural and sexual selection in the evolutionary approach are two important factors to account for the survival of the fittest. When there is a change in the environment, a danger, a situation which needs quick adaptation to survive, the individuals who adapt the fastest and the better are the ones to survive and therefore to pass on their genes onto the next generation. The individuals that fail to adapt die, and their genetic makeup is lost. In the sexual selection, individuals from every sex have genes, which provide them with attractive characteristics to attract the
This phenomenon illustrates that related animals can experience wildly different attributes: one protective and the other dangerous when obstructed. Analogous to hippopotamuses and dolphins, the male characters in Shakespeare’s play, Macbeth, have distinctly different qualities from one another. The distinction between men is made when Macbeth specifically names the “housekeeper”, or the watchdog, and the “hunter” as separate categories of masculinity. (Shakespeare.III.i.99.). Masculinity plays a large role in Macbeth because it contributes to a significant amount of reasoning behind the characters’ actions.
Our minds have created justifications to alter these guidelines when they our actions do not measure up to the social norms. Susan Bordo’s essay, “Beauty (Re)discovers the Male Body” focuses on the gender roles society has created while revealing the way the mind justifies a particular sexual way of life. Laura Kipnis’s essay, “Love’s Labors” addresses love and adultery. Kipnis addresses the common way of thinking of why and how cheating is so prevalent in today’s culture. Kipnis goes into detail about the impact love has on our way of thinking.
Provide evidence of flexible predatory behaviour and discuss why it should be more so than their prey Over evolutionary time, natural selection has shaped the morphology and behaviour of animals (Wilcox & Jackson, 1998). Therefore, many animals have evolved to be flexible predators, meaning they flexibly alter their behaviour in the face of environmental change, to ensure the successful predation of many prey species (Shettleworth, 2010). Not only this, but these predatory behaviours can be complex and illustrate an astonishing level of cognition (Jackson & Pollard, 1996). This essay provides evidence of the complex, flexible predatory behaviours of Portia, a genus of jumping spider (Salticid) (Jackson & Pollard, 1996). Distinctive from other spider species, Salticids have evolved to acquire acute vision, which is thought to have mediated the development of its diverse predatory behaviours (Jackson & Pollard, 1996).
Mass media has played a very special and important role in social influences and identifications. Beauty in our eyes of the beholder and the media is that of the beholder such as it can be a powerful agent of gender role socialization. Sex is everywhere you turn. Victoria’s Secret is notorious for their ads that plaster billboards and the sides of buildings, featuring scantily - clad women suggesting an obvious sexual air. One of the website site I will represent with sexuality media advertisement is the “Abercrombie and Fitch”.
