Predict Sex Is Better Than Postcranial Measurements

The determination of gender identity is much deeper than whether a person is born a male or a female. The exact identifier that separates gender identity is currently unknown but researchers believe that genetics, hormones, reproductive organs, biological, and environmental factors all play a role in distinguishing a person’s gender identity. A person’s physical gender and their sense of gender are formed at two different times in two different parts of the body. A person’s gender is whether they are born male or female, but the way they identify themselves may be the opposite, which is not uncommon and has occurred since the beginning of time. In culture males are known to be the stronger, more aggressive sex, while females are the

h a character's growth from childhood to adulthood changes throughout the book. The House on Mango Street by Sandra Cisneros is a perfect example of using the technique of a Bildungsroman throughout the novel. We will see how the protagonist, Esperanza in The House on Mango Street, will grow mentally and physically. Here are three specific vignettes in The House on Mango Street that will show how Bildungsroman is used; these are “Hips”, “The First Job” and “Papa Who Wakes Up in the Dark”. Body Paragraph 1 Topic Sentence:

| Researchers have found that the female hippocampus tends to be larger than the male hippocampus. Based on evidence presented in the Critical Thinking box in the text, “ 'His ' and 'Her ' Brains?” you would be justified in asserting which of the following?1. Because of the differences in the size of the hippocampus, females will be

The size and shape of the pelvis gives clues to how an animal may reproduce.

According to Hetherington and Parke (2002), studies of brain imaging identified that in female bilateralism there were greater amounts of blood flow. The male brain reflects greater lateralization attributing to a higher success rate in spatial tasks and mathematics.

Women have a different physiological structure than men. “Compared with men, women have increased pelvic width, forefoot pronation, heel

In her scientific work Sex Differences in the Brain Kimura analysis several key differences that cause men and women to excel in various tasks and jobs due to naturally occurring phenomenon in the body and

Slaby and Frey also found that boys tend to reach gender consistency before girls. This difference can't be explained by Kohlberg, since the rate of cognitive maturation is the same for both sexes. This suggests that other factors, apart from cognitive changes, must be taken into account when explaining gender

Observe skull sample and record the overall skull size, shape of forehead, supraorbital ridge, mastoid process, orbital shape, nuchal area and occipital protuberance and chin shape. Compare your observations with the information in lab book’s (table 8.1) characteristics to determine sex of the skull.

Yet, this and others, are still some of most commonly used sites for sexing. Keen (1950) expressed that because morphology is often related to size and robustness, determining sex is extremely difficult unless extreme features are expressed, such as a very small mastoid process that projects only a small distance for females and a massive mastoid process that projects a great distance from the inferior margins of the skull for males. Furthermore Meindl et al. (1985) and Walker (1995) have discussed that the morphology of sites on the skull of both sexes appear more masculine as the person ages, which would also hinder the accuracy of determining the sex of skeletal remains. Buikstra and Ubelaker (1994, p.16) also caution that "estimation of sex can be difficult if the observer is not familiar with the overall pattern of variability within the population from which the sample" they are evaluating is drawn and so as a consequence can reduce accuracy in determining sex.

Looking at male and females we can see the noticeable physical differences between the two sex, but besides exterior differences, there are subtle but significant differences within the brain. Spasificly INAH3 which is called “third interstitial nucleus of the anterior hypothalamus” which is typically about two to three times larger

For example, females usually inherit an X chromosome form both parents. Social skills which are a typical female characteristics can be found in he x chromosome. From these findings it can be said that women are more comfortable in social settings. I can think of my husband in social settings where he does not know anyone he is less likely than me to introduce himself. I have no problem introducing myself and striking up a conversation with a stranger. Hormones also have an effect on gender determination. Men and women go through maturity as a result of hormones. Estrogen in women and Testosterone influence skills and tendencies associated with gender. Sex effects how the brain develops. According to our textbook, the force of biology is evident in cases where doctors try to change a child’s biological sex” (47). Doctors mistakenly amputated David’s penis to correct phimosis, a condition in which the foreskin of the penis interferes with urination. The child’s name was changed to Brenda and she did not take to being a girl. Later in life Brenda changed her name back into David and began living a life as a male eventually getting married and raising stepchildren. I believe that biological theory is accurate match for one’s gender.

Medical researchers have been aware for a long time that the male and female brain is different in size. In 2001, researchers from Harvard found certain parts of the brain were differently sized in males and females; this may answer some of the questions about the difference in the male and female brain in regards to development and

The most basic and obvious differences observed in both genders are the physical developments such as weight, height (in

As evident from the generalized patterns found in differences in behaviour and outlook observed between the sexes, it may be tempting, as has been done in the past, to conclude that gender is an unavoidable aspect of human existence as determined purely from one 's genes. Indeed, human physiology is subject to sexual dimorphism; statistically significant differences in brain size and rate of maturation of specific substructures in the brain exist between males and females (Giedd, Castellanos, Rajapakese, Vaituzis, & Rapoport, 1997), yet these physical differences fail to explain how individuals form their concept of their own gender, and why they tend to conform to their perceived gender roles as defined by the society in which they live, when these roles are ever-changing. Thus, it is important to differentiate between the physical and nonphysical traits, and how the labels of femininity and masculinity should not confuse the two aspects. As defined by Unger (1979), “sex” would be used to refer to the biological differences in males and females, while “gender” describes socioculturally determined, nonphysiological traits which are arbitrarily designated as being appropriate for either females or males. With more recent awareness and interest in matters of gender nonconformity and individual gender identity, new research now explains how these concepts of gender are shaped by social influences (Perry
