Evolution of costly signaling and partial cooperation

Picture a woman in her early 20s, with smooth and glowing skin, shiny hair, full lips, and bright eyes. She has a perfect body figure and her voluptuous hips sway gracefully as she walks past by. Why does this type of woman appeal to men? It comes as no surprise, then, if a horde of men is lining up to impress and date the woman described above. Evolutionary psychology is the branch of psychology concerned with explaining human functions and behaviors in terms of how they increase chances of survival and reproduction. In other words, the woman is highly fertile: smooth skin, shiny hair, full lips and bright eyes indicate youthfulness, and a female of younger age has the potential of producing more children than does a female of older age. The hourglass figure is also more than just a pleasing view of good symmetry and proportion: wide hips indicate the pelvic shape most ideal for childbirth, while ample breasts cue better capacity to nourish offspring once they are born. Evolutionary psychology asserts that as a human being, the true forces that move you to act the way you do are your need to reproduce, have your genes passed on to the next generation, and ultimately ensure the survival of the species. Now, while evolutionary psychology sees men as selecting mates based on who would provide maximum opportunity for bearing offspring, it sees women in an entirely different light.

Tinder is a waste of time for most people

The Oxford Handbook of Evolutionary Psychology provides an overview of the latest developments in this fast-growing area of research. In addition to well-studied areas of investigation, such as mate choice and reproduction, the book also includes articles on the philosophical underpinnings of evolutionary psychology, comparative perspectives from other species, recent neurobiological findings, and it gets to grips with the issue of cultural evolution in relation to human psychology.

All the articles combine a review of the relevant literature with well-reasoned arguments and discussions of the major findings, as well as insights and suggestions for future work.

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.

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 interpersonal relationship.

Darwin Was Wrong About Dating

November 29, Dating apps won’t help you much if your goal is to have more relationships. You would probably succeed just as well—or poorly—without it. He is the first author of a new article in Evolutionary Psychological Science that deals with the use of Tinder. If you’re failing outside Tinder, then you don’t have much to gain from using Tinder, either.

Evolutionary psychology is a relatively new field. Scientists like Victor Johnston study the human brain and human behaviors — why we do the things we do — in the context of evolution. This clip outlines the “sweaty T-shirt” experiment, which showed that the sense of smell may have more to do with mate choice than previously thought. Females sniffing the T-shirts recently worn by males favored the scent of those whose immune response genes were different from their own.

Meredith Small and Geoffrey Miller are also interviewed. From Evolution: “Why Sex? All rights reserved. View in: QuickTime RealPlayer. Sweaty T-Shirts and Human Mate Choice: Maybe it’s not similar interests, horoscope signs, looks, or proximity that make women and men fall in love. According to evolutionary scientists, when people throw up their hands and say “it was just chemistry,” they may be on to a fundamental factor in mate choice. Subtle chemical signals, or pheromones , have long been known to draw pairs together within the same species, and for a specific reason.

In mice, for example, experiments showed that pheromones acted as attractants between males and females who were genetically similar except that they differed in a certain type of immune system gene. That difference is actually a survival benefit: The combination of two individuals’ different MHC major histocompatibility locus genes gives their offspring an advantage in beating back disease organisms.

The human capacity for positive and negative feelings is shaped by the forces of evolution, thus the evolutionary perspective should be relevant to the stu.

When it comes to the heated subject of differences between how men and women behave, debate in psychology has centered on mate preferences and general interests. The available research shows that when it comes to heterosexual mating preferences, men are relatively more interested in physical beauty, while women are relatively more interested in earning capacity. As for general interests, men are more interested in physical things, while women are more interested in people.

Even the staunchest evolutionary psychologists would acknowledge these are partially overlapping bell curves: There are plenty of men who are fascinated by other people, and plenty of women looking for physical beauty in a partner above all else. Yet the findings have been met with fierce resistance in some quarters.

At the Nature end, on the other hand, are various evolutionary psychology accounts which posit that sex differences in behavior were carved into place by evolution. One of the most noteworthy studies published in support of social roles theory came out in American Psychologist in Alice H. Elsewhere, though, the differences were robust, both in the ranked- and rated-trait data, even controlling for gender equality.

However, the new analyses match up, at least partially, with those of an important article published by Richard Lippa , who asked a similar set of questions pertaining to sex differences in personality and interests. In contrast, gender differences in interests appear to be consistent across cultures and over time, a finding that suggests possible biologic influences.

He is also working on a book about why shoddy behavioral-science claims sometimes go viral for Farrar, Straus and Giroux. I have allways wondered why, if gender preference is socially constructed, there is homosexuality. Does social construction theory see homosexuality as a result of nurture?

Her job involves incorporating theory and academic research into customer analysis, building a conceptual framework for insights into online consumer behavior. The counter-intuitive truth is that Tinder actually provides users with all the information they need to make an informed first impression about a potential long-term mate. And it does so by matching our human evolutionary mechanism.

In response to problems in our environment, we adapt both physically and psychologically to ensure our survival and reproduction. Sexual selection theory describes how evolution has shaped us to provide a mating advantage rather than just a survival advantage and occurs through two distinct pathways: intrasexual competition and intersexual selection. Gene selection theory , the modern explanation behind evolutionary biology, occurs through the desire for gene replication.

Evolutionary psychology connects evolutionary principles with modern psychology and focuses primarily on psychological adaptations: changes in the way we think in order to improve our survival. Two major evolutionary psychological theories are described: Sexual strategies theory describes the psychology of human mating strategies and the ways in which women and men differ in those strategies. Error management theory describes the evolution of biases in the way we think about everything.

In fact, you may even consider flossing your teeth for the first time all year. But how did you learn these particular behaviors? Where did you get the idea that a first date should be at a nice restaurant or someplace unique? It is possible that we have been taught these behaviors by observing others. It is also possible, however, that these behaviors—the fancy clothes, the expensive restaurant—are biologically programmed into us.

Choose me! Yes, evolution—certain traits and behaviors developing over time because they are advantageous to our survival. In the case of dating, doing something like offering a gift might represent more than a nice gesture.

Biological Approach

The human capacity for positive and negative feelings is shaped by the forces of evolution, thus the evolutionary perspective should be relevant to the study of happiness. This paper attempts to identify the more pertinent innate qualities of the human brain, and discusses how the evolutionary perspective can be used to relate these qualities to the study of happiness. Two aspects of our evolutionary legacy appear to be particularly relevant: One, the consequences of discords between the present way of living and the environment of evolutionary adaptation; and two, the presence of feelings designed to influence behaviour.

The purpose of the present paper is to both expand on these two aspects and thereby arrive at an evolutionary based description of happiness; and to discuss the relationship between this biological account and some current approached to the study of happiness.

By Saul McLeod , updated The biological approach believes us to be as a consequence of our genetics and physiology. It is the only approach in psychology that examines thoughts, feelings, and behaviors from a biological and thus physical point of view. Therefore, all that is psychological is first physiological. A biological perspective is relevant to the study of psychology in three ways:. Comparative method : different species of animal can be studied and compared.
