What is the main concept of natural selection?
Natural selection argues that animals should have characteristics that help them compete for survival, with most features having an adaptive function in the struggle for existence.
Why does Darwin argue that the process of natural selection is complemented by sexual selection?
Darwin realized that some features, like the peacock’s tail, may impair survival but have evolved because they are attractive to the opposite sex, helping with mate attraction and competition.
What is sexual selection?
Sexual selection refers to traits evolving because they are attractive to the opposite sex, and it can also involve competition between members of the same sex for access to mates.
What is intersexual selection?
Intersexual selection refers to the effects of choice by members of the opposite sex on mate selection.
What is intrasexual selection?
Intrasexual selection refers to competition between members of the same sex for access to mates.
What is the role of evolutionary psychology in human mate choice?
Evolutionary psychologists argue that mate choice behaviours evolved to maximize the chance of passing on genes, with distinct strategies for men and women based on different evolutionary pressures.
Why do females have a low potential reproductive rate?
Females have a low potential reproductive rate because they produce a few large eggs, are only fertile for a limited time each month, and invest heavily in pregnancy and lactation.
Why do males have a high potential reproductive rate?
Males have a high potential reproductive rate because they produce a large number of sperm daily, with little energy required for reproduction compared to females.
What characteristics do females prefer in males according to evolutionary theory?
Females prefer males with resources (e.g., ambition, intelligence) and older males who have had more time to gather resources.
What characteristics do males prefer in females according to evolutionary theory?
Males prefer indicators of fertility, such as youth, a curvy body, and physical attractiveness, as these suggest good genes and the ability to support offspring.
What did Buss et al. (1989) find about mate preferences?
Buss et al. found that women value earning potential and ambition more, while men value physical attractiveness and youth more, supporting evolutionary predictions.
What does the study by Buss et al. (1989) suggest about the basis of mate choice?
The study suggests that mate preferences are more likely to have a genetic basis rather than being culturally determined, as similar patterns were found across 37 different cultures.
What did Kenrick’s study reveal about mate preferences for different types of relationships?
Kenrick’s study found that intelligence is valued for marriage partners, but less important for one-night stands, suggesting mate preferences can differ depending on relationship type.
What did Clarke & Hatfield (1989) find in their study on sexual behaviour?
Clarke & Hatfield found that women were more likely to be choosy about casual sex, supporting evolutionary theory that women are more selective due to higher reproductive costs.
What is a criticism of evolutionary explanations in mate choice?
Evolutionary explanations can be criticized for being reductionist, simplifying complex social behaviour to just reproductive strategies and ignoring other factors like culture.
What is a criticism of evolutionary theories related to homosexual relationships?
Evolutionary theories struggle to explain homosexual relationships, as mate choice in such relationships doesn’t lead to increased reproductive success.
What is a criticism of the deterministic nature of evolutionary explanations?
Evolutionary explanations can be criticized for being deterministic, implying that individuals have little or no choice in partner selection, reducing the role of personal deliberation.
What is sperm competition?
Sperm competition refers to the competition between sperm from different males within the female reproductive tract, influencing the evolution of male reproductive traits.
How does testes size relate to sperm competition?
The size of testes indicates the level of sperm competition, with larger testes evolving in species where females mate with multiple males, such as chimpanzees.
What does the comparison of human testes size with other species suggest?
The comparison suggests that humans have moderately sized testes, indicating past intra-sexual selection, and that human females may be more promiscuous than initially believed.
What is self-disclosure in romantic relationships?
Self-disclosure means revealing personal information about yourself to your partner, which strengthens the bond when done appropriately.
What is the key concept in Altman and Taylor’s social penetration theory?
The key concept is self-disclosure, where partners gradually reveal deeper personal thoughts and feelings to each other.
What is the process of self-disclosure according to social penetration theory?
Self-disclosure involves a gradual exchange of personal information, progressing from superficial topics to deeper, more intimate ones, fostering trust and intimacy.
What are the two key elements of self-disclosure according to Altman and Taylor?
The two key elements are breadth (the range of topics disclosed) and depth (the intimacy of the information disclosed).
