Strategic Pluralism
Strategic pluralism (also known as the dual-mating strategy) is a theory in evolutionary psychology regarding human mating strategies that suggests women have evolved to evaluate men in two categories: whether they are reliable long term providers, and whether they contain high quality genes. The theory of strategic pluralism was proposed by Steven Gangestad and Jeffry Simpson, two professors of psychology at the University of New Mexico and Texas A&M University, respectively. Newer science does not support the theory that human females change mating preferences when ovulating; a 2018 review does not show women changing the type of men they desire at different times in their fertility cycle. Experiments and studies Although strategic pluralism is postulated for both animals and humans, the majority of experiments have been performed with humans. One experiment concluded that between short term and long-term relationships, males and females prioritized different things. It was s ...

Evolutionary Psychology
Evolutionary psychology is a theoretical approach in psychology that examines cognition and behavior from a modern evolutionary perspective. It seeks to identify human psychological adaptations with regards to the ancestral problems they evolved to solve. In this framework, psychological traits and mechanisms are either functional products of natural and sexual selection, non-adaptive by-products of other adaptive traits, or noise. Adaptationist thinking about physiological mechanisms, such as the heart, lungs, and the liver, is common in evolutionary biology. Evolutionary psychologists apply the same thinking in psychology, arguing that just as the heart evolved to pump blood, and the liver evolved to detoxify poisons, there is modularity of mind in that different psychological mechanisms evolved to solve different adaptive problems. These evolutionary psychologists argue that much of human behavior is the output of psychological adaptations that evolved to solve recurrent p ...

Human Mating Strategies
In evolutionary psychology and behavioral ecology, human mating strategies are a set of behaviors used by individuals to select, attract, and retain mates. Mating strategies overlap with reproductive strategies, which encompass a broader set of behaviors involving the timing of reproduction and the trade-off between quantity and quality of offspring. Relative to those of other animals, human mating strategies are unique in their relationship with cultural variables such as the institution of marriage. Humans may seek out individuals with the intention of forming a long-term intimate relationship, marriage, casual relationship, or friendship. The human desire for companionship is one of the strongest human drives. It is an innate feature of human nature and may be related to the sex drive. The human mating process encompasses the social and cultural processes whereby one person may meet another to assess suitability, the courtship process and the process of forming an interperson ...

Steven Gangestad
Steven Warren Gangestad is an American evolutionary psychologist who is Distinguished Professor Emeritus in the Department of Psychology at the University of New Mexico. With his University of New Mexico colleague Randy Thornhill, he has conducted considerable research pointing to the existence of concealed ovulation Concealed ovulation or hidden œstrus in a species is the lack of any perceptible change in an adult female (for instance, a change in appearance or scent) when she is fertile and near ovulation. Some examples of perceptible changes are swelling an ... in humans.

Ovulatory Shift Hypothesis
The ovulatory shift hypothesis holds that women experience evolutionarily Adaptation, adaptive changes in subconscious thoughts and behaviors related to mating during different parts of the Menstrual cycle, ovulatory cycle. It suggests that what women want, in terms of men, changes throughout the menstrual cycle. Two Meta-analysis, meta-analyses published in 2014 reached opposing conclusions on whether the existing evidence was robust enough to support the prediction that women's mate preferences change across the cycle. A newer 2018 review does not show women changing the type of men they desire at different times in their fertility cycle. Overview The theory proposes that women's behavior may change during the most Fertility, fertile time in their ovulatory cycle. At high fertility, the theory holds that women may become more physically active and avoid male relatives. The hypothesis separately proposes that Hormone, hormonal changes across the cycle cause women, when they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Extra-pair Copulation
Extra-pair copulation (EPC) is a mating behaviour in monogamous species. Monogamy is the practice of having only one sexual partner at any one time, forming a long-term bond and combining efforts to raise offspring together; mating outside this pairing is extra-pair copulation. Across the animal kingdom, extra-pair copulation is common in monogamous species, and only a very few pair-bonded species are thought to be exclusively sexually monogamous. EPC in the animal kingdom has mostly been studied in birds and mammals. Possible benefits of EPC can be investigated within non-human species, such as birds. In males, a number of theories are proposed to explain extra-pair copulations. One such hypothesis is that males maximise their reproductive success by copulating with as many females as possible outside of a pair bond relationship because their parental investment is lower, meaning they can copulate and leave the female with minimum risk to themselves. Females, on the other hand, ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexual Selection In Humans
Sexual selection in humans concerns the concept of sexual selection, introduced by Charles Darwin as an element of his theory of natural selection, as it affects humans. Sexual selection is a biological way one sex chooses a mate for the best reproductive success. Most compete with others of the same sex for the best mate to contribute their genome for future generations. This has shaped human evolution for many years, but reasons why humans choose their mates are not fully understood. Sexual selection is quite different in non-human animals than humans as they feel more of the evolutionary pressures to reproduce and can easily reject a mate. The role of sexual selection in human evolution has not been firmly established although neoteny has been cited as being caused by human sexual selection. It has been suggested that sexual selection played a part in the evolution of the anatomically modern human brain, i.e. the structures responsible for social intelligence underwent positive s ...
