Evolutionary Theory

The article talks about how different ideal body types came to be and also how these standards affect male’s body image. The authors state that previous studies have shown the negative effects of perfect body exposure to women, therefore they try to do a similar experiment to men to see if it comes to the same conclusion. It comes to conclusion that men that exposed to ideal male images became significantly more depressed

This works well if a man has broad shoulders, part of the ideal body shape for

For example: The shapes of the females that were not Caucasian had more curvature at the hips and a smaller waists'.

What are the three primary arenas of research that are used to explain biological differences between men and women?

The earliest hominine fossils show evidence of marked differences in body size, which may reflect a pattern of the different sexes in our early ancestors. The bones suggest that females may have been 3 to 4 ft in height and

Sexual selection was an idea proposed by Darwin and refers to the process in which males and females attempt to maximize their chances of reproductive success. Within a species there are certain characteristics that make individuals attractive to potential mates. An example of this is in peacocks, female peacocks are attracted to males with long brightly colored tails, even though this makes them easier to be spotted by predators. This characteristic then evolves within the species due to how males with this characteristic have a higher chance of reproductive success and their characteristics being passed on to surviving offspring.

• Be able to use the terms variation, adaptation, natural selection, and evolution as they apply to this and

In the book, The Red Queen, the author Matt Ridley claims that men find women’s ratio of waist width-to-hip width attractive (Ridley 292). It was observed by Physiologist Dev Singh who argued that a man will find a woman extremely attractive as long as her waist is much thinner than her hips (Ridley 292). In addition, this ratio is also hints if a woman is childbirth potential (Ridley 292). Throughout human time, this waist-to-hip ratio theory has changed on what is preferable (Bovet and Raymond 1). However, this sexual attraction is still a trait that influences men’s mate preference (Bovet and Raymond 1). I also found that a woman’s waist-to-hip ration also provides information about a woman’s age, and health (Bovet and Raymond 1). Overall,

There is a better chance of the traits being passed on when sexual selection is at

One of the most astonishing things on earth is the human body. They consist of many organs that work together to maintain the person alive. The humans body composition is complex, but what was the origin? How did we become who we are today? These are the questions that intrigued me, and allowed me to understand how the human body evolved over the years. By the examination of our ancestors, and our body we will understand how we look today.

How should I look like to have the ideal body? An increasing number of women ask themselves this question many times in their lives. Deborah Sullivan’s essay, “Social Bodies: Tightening the Bonds of Beauty”, discloses the different cultural traditions that require various methods of body modifications. Women should undergo such modifications to obtain social acceptance. Similarly, “Pressures to Conform” by Celia Milne discusses the effects of media and society on women, and how women view their physical appearance. The media gives women a plethora of choices for the perfect body and even provides ways on how to achieve them. There is no escaping. There is no excuse of not getting the ideal body that ranges from that of a stick-thin ramp

“If no such variations exist, the population rapidly goes extinct because it cannot adapt to a changing environment” (O’Neil, 1998-2013). Scientists call this reproductive success. “Within a specific environment context, one genotype will be better than another genotype in survival or reproduction for certain reasons having to do with the way its particular features relate to the environment or relate to other organisms within the population” (Futuyma, 2000-2014). The theory of evolution is explicable through various kinds of scientific research.

Adaptationism is the belief that the traits seen in organisms are the results of evolution by natural selection. There are different forms of adaptationism and many different definitions as to what an adaptation is, with some believing it is impossible to test a hypothesis about an adaptation at all. This essay will look at a) how to define adaptation b) different forms of adaptationism and c) consider the different methods of testing whether a phenotype is an adaptation.

Evolutionary theory is an important part of physical anthropology as it helps the researchers to have a solid
