Evolutionary Psychology

A new study explores the connection between a woman's body size and her romantic jealousy. Researchers found evidence that a woman's height and BMI are linked to how threatened she feels when she hears another woman with a highly feminine...

By analyzing the genomes of over 15,000 ancient humans, researchers have mapped how natural selection shaped traits across West Eurasia over the past 10,000 years, revealing evolutionary shifts in disease resistance, physical appearance, and complex behaviors.

A new psychological study of traditional and reversed-gender relationships reveals that when women hold dominant roles, they care less about a partner’s financial resources and place a much higher value on physical attractiveness.

A newly published hypothesis suggests that human eyes evolved from a single "third eye" on an ancient ancestor's head. This proposed evolutionary detour would explain why vertebrate vision is unique, leaving a functional remnant inside our brains.

Feeling jealous can prompt romantic partners to prioritize defending their relationship over routinely nurturing it. Over time, this defensive focus creates a self-reinforcing loop that can increase jealousy and quietly erode long-term relationship satisfaction.

For decades, testosterone has been blamed for reckless behavior and risky financial gambles. However, a massive new meta-analysis of over 17,000 participants reveals that the link between the "macho" hormone and risk-taking is essentially zero.

Sexual objectification is often blamed on toxic personality traits, but new research suggests a more universal trigger. A recent study provides evidence that temporary states of sexual arousal cause men to objectify women, regardless of their underlying character.

New research indicates that while going braless is viewed as more attractive, it also leads to perceptions of infidelity, prompting many women to wear bras to avoid unwanted sexual harassment.

Can we successfully outsource love? A new evolutionary psychology paper argues that virtual "girlfriend experiences" are booming because they offer users the emotional and sexual rewards of dating without the evolutionary costs of mutual mate selection and conflict.

Both men and women experience intense jealousy when a romantic partner actively gives resources to a stranger. New research indicates that our emotional alarm systems react much stronger to a partner giving rather than receiving attention.

Gold digging is often viewed as a female stereotype, but new research suggests it is a broader human mating strategy. The study provides evidence that both men and women use this exploitative approach, which is heavily linked to psychopathy and...

A recent study suggests that stories about dangerous, attractive women are almost universal across cultures. These cautionary tales provide evidence that evolutionary fears of emotional deception and heartbreak heavily influence human mating psychology.

New research in Evolution and Human Behavior suggests the social benefits of gaming depend on the context. While games might not immediately forge friendships, computer simulations indicate the behavior evolved as a survival strategy to assess potential allies.

Smarter men tend to display physical signs of good health, like strong grips and broad shoulders. Yet, a recent study shows these men engage in less casual sex, suggesting intelligence steers them toward committed, long-term romantic partnerships.

As more women earn college degrees, marriage patterns are transforming across the globe. New demographic research disentangles whether a reversing educational gender gap or an overall boom in university attendance is driving these modern relationship shifts.
