POPSWhy kindness has become our forbidden pleasure? "What is to be done? Nothing, many would say. Human beings are innately selfish and that is that. Newspapers bombard us with scientific evidence to back up this pessimism. We read about greedy chimpanzees, selfish genes, ruthless mate-selection strategies, even about meerkats - those famously cooperative creatures - who instead of looking out for their fellows spend most of their time "watching their own backs". Richard Dawkins of "selfish gene" fame lays it on the line: "Human society based simply on the gene's law of universal ruthless selfishness would be a very nasty society in which to live. But unfortunately, however much we deplore something, this does not stop it being true ..." Yet Dawkins does not despair: "If you wish, as I do, to build a society in which individuals cooperate generously and unselfishly towards a common good, you can expect little help from biological nature. Let us try to teach generosity "

POPSWhy Life Originated (And Why it Continues)
Although the researchers don’t speculate on the specific chemical reactions that created life, they explain that the molecules involved most likely underwent a series of more and more complex reactions to minimize mutual energy differences between matter on Earth and with respect to high-energy radiation from Sun. The process eventually advanced so far that it cumulated into such sophisticated functional structures that could be called living. The researchers considered a primordial pool that contained some basic compounds. By reacting with one another and coupling with an external energy source such as the Sun, the compounds formed a chemical system. The compounds continually engaged in chemical reactions, thriving the most when capturing and distributing more and more of the Sun’s energy in the quest for a steady state. The evolutionary process was and still is non-deterministic, even chaotic, since the energy flows create energy differences that in turn affect the flows.

POPSWhy do humans kiss? "Still, most people are satisfied with the explanation that humans kiss because it feels good. Our lips and tongues are packed with nerve endings, which help intensify all those dizzying sensations of being in love when we press our mouths to someone else’s. Experiencing such feelings doesn’t usually make us think too hard about why we kiss – instead, it drives us to find ways to do it more often".

POPSPolygamy is the key to a long life Men, by contrast, can reproduce well into their 60s and even 70s and 80s, and most researchers assumed this explained their longevity. But Lummaa and colleague Andy Russell wondered whether other factors explained the long lifespan of men, such as a grandfather effect. If female survival is the main explanation for male longevity, then monogamous and polygamous men would live for about the same length of time. Instead, it seems that fathering more kids with more wives leads to increased male longevity. Men, then, live long because they're fertile well into their grey years. The explanation could be both social and genetic. Men who continue fathering kids into their 60s and 70s could take better care for their bodies because they have mouths to feed. But evolutionary forces acting over thousands of years could also select for longer-lived men in polygamous cultures.

POPSStudy: 93% Of People Talked About Once They Leave Room "As well as their breath, body odor, speech patterns, and the way they walked, not to mention general discussion based on the perception that the participant who had left the room was most likely a world-class prick." According to the data, 89 percent of volunteers appeared to listen attentively to the subject's receding footsteps, 47 percent raised their eyebrows and smirked as the subject left, and 23 percent mouthed the words "what the fuck" to others in the room as the door was closing, which usually triggered bouts of stifled giggling Perhaps most exciting was the 9 percent of volunteers who silently flipped the subject off as they left the room, Phillips said the lower-order cognitive functions responsible for knee-jerk gossiping may have played an ancient role in survival by encouraging those in proximity to band together.

POPS How altruism evolved over 200,000 years of conflict Biologists have argued for decades about the evolution of altruism and long ago came to the conclusion that Darwinian natural selection cannot explain acts of supreme personal sacrifice except those directly connected with helping the survival of close blood relatives who share similar genes.

POPSA Most Private Evolution Trying to understand counterintuitive sexual parts and habits follows in the best of scientific traditions. As Charles Darwin worked on evolution, he pondered male phenomena that looked useless, or even harmful, for surviving. Outsized horns on male beetles puzzled him, as did male birds with gorgeous plumage. Out of this consternation came his insight into a process he called sexual selection, which he distinguished from natural selection. There may be survival of the fittest, but there’s also survival of the sexiest. “The sight of a feather in a peacock’s tail, whenever I gaze at it, makes me sick!” Darwin wrote in a letter to the botanist Asa Gray, albeit in a whimsical paragraph. Nauseated or not, Darwin was willing to step beyond survival of the fittest.

POPSFemale Fighters: We Won't Stand for Male Dominance Back in 1998, the fighters say, their now-jailed leader Abdullah Ocalan declared the group "a women's party." It was initially difficult to accept, says Karim, a 42-year-old male member of the PKK. Today, the PKK's ideology revolves around a belief that global crises and injustice are a result of millennia of male-dominated rule. Here, the women run their own assaults and have their own command structure. All tasks are shared, both on and off the battlefield. Discipline is paramount to survival, they say, and weapons are always clean and never out of reach.

POPSWhat Makes People Racist? The researchers say that negative associations likely have such power in most people's minds because evolution prepared us to notice bad things more than good things. “If there’s a lion hiding in a bush, you’d better see it,” . “Whereas if there’s a tree of mangoes, it’s unfortunate if you don’t notice it, but it’s not as critical to your survival. ” Since each negative association has more weight in the brain, one must overcompensate with many positive links just to get back to neutral. The psychologists aren’t clear on why some people don’t make negative associations, but they are looking for genetic and social factors that predict it. Unfortunately, other research shows that simply wanting to be less negative -- or less racist -- won't actually work. You have to do something about it. The best way to become less racist, say psychologists, is to spend time with the very people you're prejudiced against.

POPSNew Research On Octopuses Sheds Light On Memory It is not completely understood how these two systems are interconnected, if at all. However, the organization in the octopus demonstrates a sophistication that was not described yet in other animals. In the octopus, the short-term and long-term systems are working in parallel, but not independently. This is so because the long-term memory area -- in addition to its capacity to store long-term memories -- also regulates the rate at which the short-term memory system acquires short-term memories. This regulatory mechanism is probably useful in cases where faster learning is significant for the octopus' survival in emergency or risky situations.

POPS‘Leopard Behind You!’ A human in a blue shirt is announced differently from a human in a yellow shirt. In and of itself, it’s not surprising that the sounds animals make are not just noise, or a reflection of the state an animal’s in (scared, happy and so on). But the subtlety of the calls — the full amount of meaning they contain — is only now being appreciated. Animals of one species often respond to the alarms of another. In a small way, it’s like those childrens’ stories that have rats talking to toads, or elephants arguing with ostriches. Predators sometimes respond too. After all, alarm calls don’t just let other animals know there’s danger in the area. They can also let a predator know that it’s been seen. Ambush predators, like leopards, often give up and go away once an alarm has been sounded. <<

POPSFear Factor: How Herd Mentality Drives Us
"Whether it's the fear of being the odd person out, whether it's the fear of uncertainty or the fear of losing your shirt in the market, the fear starts to compel you to do something, because a million years ago, that fear meant you probably had to run or fight," Berns said. But reactions that saved our ancestors from saber-toothed tigers don't make as much sense on the floor of the Stock Exchange. Financial historian Jeff Madrick says that's how we got into trouble in the first place - by developing the notion that the stock is highly rational. "That encouraged this herd behavior," he said. "People would say, 'The stock market is right. Let's get in here.' That was the mythology that fed the herd behavior." So the group think that helped build the bubble is now leading the charge to pop it. "I think there's probably a panic now," Madrick said. Berns agreed: "You could call it panic; I would." But the Bronx Zoo's Pat Thomas says, "It's definitely a survival mechanism."

POPSThe World's Oldest Temple - 12,000 year-old Gobekli Tepe From Archaeology Magazine's November/December 2008 issue... The press here is fond of calling the site "the Turkish Stonehenge," but the comparison hardly does justice to this 25-acre arrangement of at least seven stone circles. The first structures at Göbekli Tepe were built as early as 10,000 B.C., predating their famous British counterpart by about 7,000 years.
