It used to be thought that humans were the only savagely violent primate. “We are the only species that kills its own,” narrators intoned portentously in nature films several decades ago. That view fell by the …
Culture is the knowledge, beliefs, behavior, outlook, attitudes, values, goals, traditions, and practices shared by a group of people that cannot be attributed to genetics. We define culture as the universal human ability to encode and transmit our experiences symbolically. Anthropologist Rob Boyd calls culture the “engine of human adaptation,” explaining that it was by accumulating and...
Did female competition lead to covert aggression?
Being Human ,
It isn’t just characters in films like Mean Girls and Heathers that backstab and gossip. It turns out that women may have evolved to do just that, according to a new article by Tracy Vaillancourt in the journal Philosophical Transactions of the Royal Society B. She argues that women use indirect aggression to remove the threat of sexual rivals.
"Women do compete, and they can compete quite fiercely with one another," said Tracy Vaillancourt, the paper's author and a psychology professor at the University of Ottawa in Canada. "The form it typically takes is indirect aggression, because it has a low cost: The person [making the attack] doesn't get injured. Oftentimes, the person's motives aren't detected, and yet it still inflicts harm against the person they're aggressing against."
It has been shown in many cultures, that while men often use physical aggression to deal with competition, women will more likely use indirect aggression to handle perceived threats. This led to Vaillancourt’s idea that there must be an evolutionary component to the cattiness and backbiting that occurs between women.
With the first hint of a crisp cool autumn breeze, couples everywhere begin pairing off in a seemingly magical phenomenon known as cuffing season. Cuffing season, as defined by UbranDictionary.com, is a yearly occurrence around the fall and winter months when normally promiscuous singles begin to look for serious relationships (becoming “cuffed” or tied down) due in part to colder weather creating a high propensity for canoodling indoors. Cuffing behavior is likely influenced by the weather and perhaps the dramatic increase in sappy, love-saturated jewelry commercials aired ad nauseam around the holidays. However whimsical cuffing season may seem, true evolutionary and neurobiological causes underpin the many reasons why people enter into monogamous relationships.
Monogamy is not something that comes naturally to mammals. Mammalian males do not often take it upon themselves to stick around during long gestational periods and breast-feeding when they could be out-and-about looking for their next available mate to further propagate their genomic line. This notion of promiscuity is in congruence with Charles Darwin’s “survival of the fittest” evolutionary theory where the more seed you spread, the more likely you will have offspring to carry on your genes. But scientists think that despite the inclination for mammals to engage in casual sexual relationships, the evolutionary foundation of monogamy in human beings is likely based on protection, care, and survival of children.
“Started from the bottom, now we here” is more than just a catchy Drake hook that youth twerk to in the club; it is a sentiment echoed throughout rap and hip-hop culture. From The Notorious B.I.G. to Eminem, rap music celebrates rags-to-riches stories that trace a persons ascent from crushing poverty to enormous wealth and icon status.
While the majority of rap songs focus on money, these recording artists may actually be improving more than their financial situation as they climb the rungs of the social class ladder—they may actually be improving their health. Research conducted with rhesus monkeys suggests that music moguls and laypeople alike may enhance their long-term health by moving up in the socioeconomic hierarchy, which alters regulation and expression of immune system-related genes.
We've known for a while that health is irrevocably tethered to socioeconomic status. The well-known Whitehall study was the first of its kind to definitively demonstrate this link. Surveying 18,000 British civil servants ranging in occupations from messengers to high-ranking government officials, the study concluded that men in the lowest grades of employment have higher mortality rates compared to those working at the top of the career totem pole. Additional studies have shown that lower social classes are more vulnerable to asthma, cancer, cardiovascular disease, diabetes, and infectious diseases.
Can we augment ourselves into a better future?

In June, Rich Lee had two small magnets embedded into his tragi, the fleshy portions of the ears that jut out over the ear canal. Rich’s subdermal implants—which he adapted from an Instructables project—are able to receive input from pretty much anything that he can hook up his amp to. He already listens to music without headphones, but he’s got far bigger plans. A simple directional microphone would allow Rich to eavesdrop on distant conversations, and an ultrasonic rangefinder would let him pick up the movements of nearby objects (giving their owner a capacity akin to echolocation). With the addition of a geiger counter, he could even detect radiation.
Our mission at BeingHuman.org is to examine how and why we came to be the species we are today; but we’ve also got an eye on the species we may become tomorrow. Invisible headphones are just one small part of a fascinating and polarizing movement whose undertakings also include enhancements like magnetic fingers, the possibility of self-created synesthesia, and a DARPA-funded device for keeping fatigue at bay by rapidly cooling muscle cells. Transhumanism is rooted in the idea that science and engineering can fundamentally change the nature of the human condition for the better—physically, mentally, and in any other way our prodigious imaginations can come up with.
What would life be like if you lacked a Theory of Mind (ToM) ? For one thing, it would be a lot more serious. Take this scene from a British sitcom about an elderly lady who overhears her family discussing an ailing dog—the humor in it relies entirely on the audience’s ability to infer that the woman mistakenly believes they’re talking about her, and to understand how this would make her feel. Human beings aren’t the only species to possess at least some form of ToM , which some psychologists refer to as “mind-reading”—but we may the only one that can learn to enhance it.A new Science study suggests that reading literature—at least a certain kind—may strengthen the skills that underlie ToM. In the study, David Comer Kidd and Emanuele Castano—social science researchers at New York City’s New School—conducted a series of experiments using the same basic format. In each, volunteers were randomly assigned either to a group that read a short excerpt the researchers considered emblematic of “literary fiction,” or to a comparison group. For example, participants in the fiction group might read a passage from the Chekhov short story Chameleon, about a hypocritical police inspector whose ideas about justice change and change again, depending on the mood of the crowd surrounding him. At the same time, readers in the comparison group might be given a passage from a fact-based article—something like a Smithsonian magazine piece entitled "How the Potato Changed the World”—a passage from what the researchers considered “popular fiction”—something like a best-selling Danielle Steele novel—or nothing at all.
The pitfall of studying (only) success

Imagine a coin-tossing tournament. The last man standing—the ultimate survivor—will have won every single one of his coin tosses in a row. Should we ask him what his secret was?
Don’t laugh; it’s a good bet that at some point in your life you’ve fallen prey to some version of the survivorship bias, an incredibly pervasive cognitive illusion that makes an appearance whenever failures disappear or become hidden from view. Have you ever marveled at the purring engine of a classic car, run your fingers down the smooth seams of a vintage coat, or tested the steel on your grandfather’s old hunting knife? Maybe you thought, “They just don’t make things like they used to!” It’s a romantic idea—that people in some hazy, nostalgic past really valued workmanship and quality; that old objects have a kind of inherent staying power.
What you probably didn’t think about, in those moments, were all the classic cars that ended up broken down in junkyards. You didn’t consider the coats whose seams had already fallen apart. All you saw were the things that survived to tell their stories. In the context of antique shopping, its effects are fairly innocuous—but David McRaney offers an intuitive example of survivorship bias and a matter of life and death at his blog You Are Not So Smart. During World War II, McRaney explains, military engineers wanted to figure out how to make bomber planes safer for the pilots who risked their lives to fly them. When the engineers looked at returned planes, they saw that bullet damage clustered in three main places: the wings, the body, and the rear gunner. These, then were the places they suggested be reinforced with extra armor.
