This leads to male-female dimorphism, which is accentuation of secondary sexual characteristics in those with greater reproductive fitness.

Both males and females have evolved with different preferences.
For example, males are attracted to females who ‘display’ signs of fertility and good health and are more likely to demonstrate promiscuous behaviours.
This is because it is advantageous for males to mate as often as possible to enhance their reproductive success.
Females, however, are attracted to males who can physically protect them and their offspring and have the ability to provide/invest resources in their potential offspring.
Therefore, females are more likely to demonstrate selective or choosy behaviours in an attempt to find the most suitable male for them and their potential offspring.

The first AO3 PEEL paragraph is that there is research support for intersexual selection.
For example, Clarke and Hatfield conducted research where confederates were instructed to approach both male and female students on a university campus and ask one of three questions.
The most pertinent question in the research was ‘I find you very attractive, would you go to bed with me?’
Clarke and Hatfield found that 75% of males were willing to have sex with a stranger, whereas no females were.
This supports the evolutionary theory, because it suggests that females are more selective when choosing a sexual partner, whereas males use a different strategy in order to enhance their reproductive success.

The second AO3 PEEL paragraph is that However, partner preferences over the past century have undoubtedly been influenced by rapidly changing social norms of sexual behaviour.
These develop much faster than evolutionary timescales imply and have instead come about due to cultural factors such as the availability of contraception.
Women’s greater role in the workplace means that they are no longer dependent on men to provide to them (despite the ongoing inequality in earning power).
This is supported by Bereczkei et al. (1997), who argue that women now look for men who are family-orientated and not resource-orientated.
This shows that evolutionary theories do not fully take into account the social factors involved in partner preferences and therefore ignore the role of nurture in partner preferences.
For example, Levinger et al. (1970) found that women value resources more in cultures where their status and educational opportunities are limited.
This shows that evolutionary explanations do not necessarily account for all partner preferences in 2020.

Third AO3 PEEL paragraph

Answer 24

The third AO3 PEEL paragraph is that evolutionary explanations focus on reproductive success and so are unable to explain homosexual relationships and why they exist, as they serve no reproductive value, since no children are produced

Question 25

Discuss evolutionary explanations for partner preferences (16 marks)/Discuss the relationship between sexual selection and human reproductive behaviour (16 marks). Natural selection theory is that genes that confer reproductive advantage will increase in the gene pool. Darwin's theory of sexual selection explains the evolution of characteristics that provide a reproductive advantage, focusing on two key ideas - intersexual selection and intrasexual selection. Intersexual selection is the evolution of preferences for certain characteristics/qualities within members of the same sex. For example, all females evolving to prefer tall and muscular men. Intrasexual selection is where members of the same sex (usually males) compete with one another to attract members of the opposite sex (usually females). For example, males competing against one another to attract a female. This leads to male-female dimorphism, which is accentuation of secondary sexual characteristics in those with greater reproductive fitness. Both males and females have evolved with different preferences. For example, males are attracted to females who 'display' signs of fertility and good health and are more likely to demonstrate promiscuous behaviours. This is because it is advantageous for males to mate as often as possible to enhance their reproductive success.

This raises serious ethical issues, because people may use sexual selection theory to highlight the 'abnormality' of homosexuality and create prejudice through homophobia

One is that males will show a preference for the female body shape of the typical hourglass figure, which signals fertility and demonstrates to males that she has the qualities required to rear children (and therefore this becomes attractive to them). Who is this supported by?

Answer 33

This is supported by Singh (1993), who found men preferred waist to hip ratios (WHR) of 0.7 across cultures

Question 34

Discuss evolutionary explanations for partner preferences (16 marks)/Discuss the relationship between sexual selection and human reproductive behaviour (16 marks). Natural selection theory is that genes that confer reproductive advantage will increase in the gene pool. Darwin's theory of sexual selection explains the evolution of characteristics that provide a reproductive advantage, focusing on two key ideas - intersexual selection and intrasexual selection. Intersexual selection is the evolution of preferences for certain characteristics/qualities within members of the same sex. For example, all females evolving to prefer tall and muscular men. Intrasexual selection is where members of the same sex (usually males) compete with one another to attract members of the opposite sex (usually females). For example, males competing against one another to attract a female. This leads to male-female dimorphism, which is accentuation of secondary sexual characteristics in those with greater reproductive fitness. Both males and females have evolved with different preferences. For example, males are attracted to females who 'display' signs of fertility and good health and are more likely to demonstrate promiscuous behaviours. This is because it is advantageous for males to mate as often as possible to enhance their reproductive success. Females, however, are attracted to males who can physically protect them and their offspring and have the ability to provide/invest resources in their potential offspring. Therefore, females are more likely to demonstrate selective or choosy behaviours in an attempt to find the most suitable male for them and their potential offspring. The first AO3 PEEL paragraph is that there is research support for intersexual selection. For example, Clarke and Hatfield conducted research where confederates were instructed to approach both male and female students on a university campus and ask one of three questions. The most pertinent question in the research was 'I find you very attractive, would you go to bed with me?' Clarke and Hatfield found that 75% of males were willing to have sex with a stranger, whereas no females were. This supports the evolutionary theory, because it suggests that females are more selective when choosing a sexual partner, whereas males use a different strategy in order to enhance their reproductive success. The second AO3 PEEL paragraph is that However, partner preferences over the past century have undoubtedly been influenced by rapidly changing social norms of sexual behaviour. These develop much faster than evolutionary timescales imply and have instead come about due to cultural factors such as the availability of contraception. Women's greater role in the workplace means that they are no longer dependent on men to provide to them (despite the ongoing inequality in earning power). This is supported by Bereczkei et al. (1997), who argue that women now look for men who are family-orientated and not resource-orientated. This shows that evolutionary theories do not fully take into account the social factors involved in partner preferences and therefore ignore the role of nurture in partner preferences. For example, Levinger et al. (1970) found that women value resources more in cultures where their status and educational opportunities are limited. This shows that evolutionary explanations do not necessarily account for all partner preferences in 2020. The third AO3 PEEL paragraph is that evolutionary explanations focus on reproductive success and so are unable to explain homosexual relationships and why they exist, as they serve no reproductive value, since no children are produced. This raises serious ethical issues, because people may use sexual selection theory to highlight the 'abnormality' of homosexuality and create prejudice through homophobia. Evolutionary explanations also cannot explain why some couples choose not to have children either, because they assume that all relationships are motivated by the desire to reproduce, but people get into relationships for many reasons beyond this, too. Arranged marriages have also existed for centuries, yet such behaviour goes against the theory, as no selection between males is taking place (or very little). This also shows how cultural factors also play a role in human reproduction which undermines evolutionary explanations. The fourth AO3 PEEL paragraph is that evolutionary explanations make several predictions about partner reference that can be tested empirically. One is that males will show a preference for the female body shape of the typical hourglass figure, which signals fertility and demonstrates to males that she has the qualities required to rear children (and therefore this becomes attractive to them). This is supported by Singh (1993), who found men preferred waist to hip ratios (WHR) of 0.7 across cultures. Why is this combination of wider hips and narrower waist attractive?

Answer 34

This combination of wider hips and narrower waist is attractive, because it is an 'honest signal' (hard to fake) that the women is fertile, but not currently pregnant

This suggests that evolutionary explanations are valid when explaining relationships
