The Cultural Evolution Of Religion

Sun, 12 Oct 2008 00:15:46 GMT

clipped by: wildcat

First off, let me clear the field of an obvious source of what I think is rather fruitless discussion. The authors begin by summarizing three models of the evolution of religion: the evolutionary group selection scenario (religion as an adaptation for group living), the cultural by-product scenario (religion derives from the necessity of a theory of others’ mind and sensitivity to one’s reputation), and the cultural group selection scenario (where competition among social groups favors the spread of costly practices to maintain in-group cohesion).

To begin with, they debunk the oft-repeated claim that religiosity increases charitability. It turns out studies that have made that link are entirely based on self-reporting, a notoriously unreliable source of behavioral evidence

A series of “Good Samaritan” studies found that people’s actual (as opposed to self-reported) charitable behavior shows no correspondence whatsoever with the degree of religious belief

Grid of 100,000 computers heralds new internet dawn

clipper's remarks: The Grid is coming

Clip Source: technology.timesonline.co.uk

A network of 100,000 computers providing the greatest data processing capacity yet unleashed has been created to cope with information pouring from the world’s largest machine.

The Grid is the latest evolution of the internet and the world wide web and computer scientists will announce on Friday that it is ready to be connected to the Large Hadron Collider (LHC).

It is designed for schemes where huge quantities of data need crunching, such as large research and engineering projects. The Grid has the kind of power required to download movies in seconds, and the ability to make high-definition video phone calls for the same price as a local call. More importantly, it should help to narrow the search for cures for diseases. However, it is unlikely to be directly available to most internet users until telecoms providers build the fibre-optic network required to use it.

Richard Dawkins- the believer

Dawkins has achieved not only recognition but considerable notoriety—the result, it sometimes seems, of having proposed or defended one controversial idea after another. Over the course of his career he has become associated with, and at times served as a spokesperson for, views and positions including sociobiology, biological reductionism, the gene-centered view of evolution, memetics, atheism, and secular humanism. While he is a prominent Darwinist, Dawkins entirely eschews so-called “Social Darwinism.” He is deeply committed to a progressive agenda that aims to decrease violence and oppression and improve the quality of people’s lives, not only by employing the means of science but by encouraging a better understanding of science.

THE BELIEVER: Why do you think it is that in the United States in particular, the level of ignorance about, and resistance to, Darwinian evolution is so high?

clipper's remarks: Video games are reshaping how we perform and promote science. A review by Seed Mag

Clip Source: www.seedmagazine.com

The digital revolution now engulfing our world emerged from the events during and immediately after the Second World War, when intellectual titans such as Alan Turing, John von Neumann, Norbert Wiener, and Claude Shannon roamed the Earth. Many of the predictions they made for the future in those early days are now reality, or something close to it. Turing foresaw computers as artificial intelligences. Neumann imagined machines that could reproduce themselves. Wiener guessed at a merging of biology and technology, and Shannon predicted the primacy of pure information over physical matter. But were these "founding fathers" to somehow see the state of modern computer science, they might be surprised that some of their wildest dreams are being fulfilled not under the explicit auspice of research, but of recreation

Kluge: The Haphazard Construction of the Human Mind

Fri, 05 Sep 2008 15:57:38 GMT

clipper's remarks:
Trial-and-error evolution
According to Gary Marcus's Kluge our brains are an engineering nightmare, says Steven Rose

Clip Source: www.guardian.co.uk

The fallibility of the human mind is a source of continual frustration to philosophers, artificial intelligencers and evolutionary psychologists. Our memories are weak, we are credulous and easily led to believe improbable or impossible things, our language is not optimally constructed. We have problems with probabilities, and are logically inconsistent. We make choices that are apparently irrational and not in our own best long-term interests, and certainly not in those of our genes. Thus - according to Marcus - we prefer instant gratification to the chance of greater, longer-term benefits. We get drunk, embark on non-procreative sex for mere pleasure, and may even sacrifice our lives for some perceived cause that has nothing to do with increasing our inclusive (genetic) fitness.

His chapter on language as a kluge, full of grammatical and linguistic incongruities, is particularly strong, although his basic argument is almost drowned in a flood of examples

Animal Intelligence and the Evolution of the Human Mind

Wed, 03 Sep 2008 11:50:26 GMT

clipper's remarks: Subtle refinements in brain architecture, rather than large-scale alterations, make us smarter than other animals

Clip Source: www.sciam.com

The human brain lacks conspicuous characteristics—such as relative or absolute size—that might account for humans’ superior intellect.

Researchers have found some clues to humanity’s aptitude on a smaller scale, such as more neurons in our brain’s outermost layer.

Human intelligence may be best likened to an upgrade of the cognitive capacities of nonhuman primates rather than an exceptionally advanced form of cognition.

As far as we know, no dog can compose music, no dolphin can speak in rhymes, and no parrot can solve equations with two unknowns. Only humans can perform such intellectual feats, presumably because we are smarter than all other animal species—at least by our own definition of intelligence.

Of course, intelligence must emerge from the workings of the three-pound mass of wetware packed inside our skulls

Thus, researchers have tried to identify unique features of the human brain that could account for our superior intellectual abilities

Where Is Human Evolution Heading?

clipper's remarks: The race's DNA is changing faster than ever; what it means for our descendants

Clip Source: www.usnews.com

If you judge the progress of humanity by Homer Simpson, Paris Hilton, and Girls Gone Wild videos, you might conclude that our evolution has stalled—or even shifted into reverse. Not so, scientists say. Humans are evolving faster than ever before, picking up new genetic traits and talents that may help us survive a turbulent future.

Much remodeling has gone on since the dawn of agriculture about 10 millenniums ago. "People who lived 10,000 years ago were much more like Neanderthals than we are like those people," says John Hawks, a professor of anthropology at the University of Wisconsin. "We've changed."

Hawks is among a growing number of scientists who are using whole-genome sequencing and other modern technologies to zero in on just how we've changed. Their research is helping illuminate not only how humans became what we are but also where we might be headed

Humans will continue to change to cope with new diseases, if history is any guide

The Zombification Of Philosophy (Of Mind)

clipper's remarks: Massimo Pigliucci is Professor in the Departments of Ecology & Evolution and of Philosophy at Stony Brook University, NY.

an interesting view , go read it

Clip Source: www.scientificblogging.com

David Chalmers is a famous philosopher of mind. His fame rests in great part on his 1996 book, The Conscious Mind: In Search of a Fundamental Theory. It’s too bad that the crucial idea behind the book, dualism, is hopelessly flawed, and -- more surprising yet -- that Chalmers got away with one of the most idiotic thought experiments ever, which a lot of people inexplicably seem to think is oh-so-very clever.

Let us start by recalling what dualism is: in philosophy the idea traces back at least to Descartes (though some would consider Plato a dualist), and his contention that while everything else in humans and animals is “mechanical” (i.e., made of matter), the mind is an exception, since it’s made of some kind of distinct mind stuff (he was pretty vague about exactly what this mind stuff might be, and so is Chalmers, incidentally

I think a lot of scientists do a disservice to themselves and to the public by not taking philosophy seriously

The Death of HAL –the Evolving Digital Ecosystem

Clip Source: www.dailygalaxy.com

One of the greatest fears of many is the underlying knowledge that, all the wonderful advances of technology, the internet and robotics is simply bringing us closer to being subservient to our robotic overlords. It is essentially a historical imperative, and we can see it coming a mile away.

However British Computer Society President and ECS Professor of Artificial Intelligence Nigel Shadbolt, believes differently.

Instead of intelligence that is a “brain in a box”, we are seeing intelligence that is assistive, adaptive and flexible. They are helping us “drive our cars, diagnose disease and provide opponents in computer games.”
In other words, instead of an intelligence that is “…agonizing about their existence or whether we are about to switch them off” we are seeing the growth of intelligence that, in years to come, will immerse us and center around humans, rather than feel the need to enslave humans.

clipper's remarks: A fascinating example of cooperation we have right here at CM

Clip Source: www.scientificblogging.com

Why do humans cooperate in things as diverse as environment conservation or the creation of fairer societies, even when they don’t receive anything in exchange or, worst, they might even be penalized?

This is a question that has puzzled academics Why do humans cooperate in things as diverse as environment conservation or the creation of fairer societies, even when they don’t receive anything in exchange or, worst, they might even be penalized? This is a question that has puzzled academics for centuries, especially since in evolution the basis for the “survival of the fittest” is, after all, selfishness.

But in an article just published in the journal Nature, three Portuguese theoretical physicists developed a mathematical model capable of providing a way out from this conundrum through the introduction of social diversity

the act of cooperation may depend on one’s social context/ranking

when social diversity was taken into account

the numbers of those cooperating increased

Future Human: The Evolution of Immediate Emotion

Fri, 18 Jul 2008 11:23:56 GMT

clipped by: wildcat
clipper's remarks: Humans, apparently, are still in the early stages of evolving extended response mechanisms. But it seems likely that by the time we portion more of our brain to long-term dangers, there will be few grizzly bears around to worry about, and a whole lotta global warming.

Clip Source: www.popsci.com

Why a grizzly gets you shivering—but not global warming

In my Science Confirms the Obvious post today, I discussed the first psychological proof (so say the authors) that humans can indeed experience emotions without immediately knowing why. We do this, they say, because we evolved that way. True, scientists love that explanation, but here it’s quite intriguing.

“After all, you are likely to live longer if you immediately stop moving at the sight of a growling grizzly bear,”

“and do not need full awareness for such a response to be instigated.” Given the flood of unexpected stimuli we face moment to moment, quick reactions make sense for survival.

You, that bear, and other animals experience emotions such as fear, anger, or disgust. But only a few species are aware of their emotions. This ability helps humans judge and respond to the behavior of others in order to navigate social situations and, ultimately, grease the wheels of complex society.

Life's Increasing Complexity Spurred Evolution of Human Brain

Thu, 10 Jul 2008 11:47:58 GMT

Clip Source: www.dailygalaxy.com

Whether it be a week ago, or a couple of thousand years ago, humans have always needed split second thinking to avoid life threatening situations. Whether it would be a sudden and cataclysmic encounter with a semi-truck, or a similar encounter with a disgruntled lion, quick thinking has always been necessary.

But we don’t always need split second thinking; sometimes we just need to take in all the information, and process it. Slowly.

According to new research from the University of Bristol, lead by Pete Trimmer, and published Tuesday in the Proceedings of the Royal Society B., those two types of thinking are completed by two separate areas of our brains.

For a long time scientists have believed that mammals have two decision making systems in their brains, each one operating at different speeds depending on the situation around them. Trimmer’s research shows that the older, more instinctual and thus less accurate thinking may have helped shape the more recent, methodical thinking.

“What is Life?” Evolution of Robots is Causing Scientists to Question

Tue, 01 Jul 2008 10:04:36 GMT

clipped by: wildcat
clipper's remarks: “Robots are not human, but humans aren’t the only things that have emotions,” she said. “The question for robots is not, Will they ever have human emotions? Dogs don’t have human emotions, either, but we all agree they have genuine emotions. The question is, what are the emotions that are genuine for the robot?”

Clip Source: www.dailygalaxy.com

There is ongoing debate about what constitutes life. Synthetic bacteria for example, are created by man and yet also alive. Some go so far as to say that robot “emotions” may already have occurred—that current robots have not only displayed emotions, but in some ways have experienced them.

“We’re all machines,” says Rodney Brooks author of “Flesh and Machines,” and former director of M.I.T.’s Computer Science and Artificial Intelligence Laboratory, “Robots are made of different sorts of components than we are — we are made of biomaterials; they are silicon and steel — but in principle, even human emotions are mechanistic.” A robot’s level of a feeling like sadness could be set as a number in computer code, he said. But isn’t a human’s level of sadness basically a number, too, just a number of the amounts of various neurochemicals circulating in the brain? Why should a robot’s numbers be any less authentic than a human’s?

CULTURAL EVOLUTION

Sat, 28 Jun 2008 11:35:46 GMT

clipped by: wildcat
clipper's remarks: We are finally starting to understand the patterns of culture change and the role of natural selection in shaping them. And since everything from weapons of mass destruction to global heating are the results of changes in human culture over time, acquiring a fundamental understanding of cultural evolution just might be the key to saving civilization from itself.

Clip Source: www.seedmagazine.com

Does human culture evolve via natural selection, as our genes do?

Biologists have a pretty good idea of both how flies become resistant to DDT and how humans and primates have diverged over time. That's because the mechanism underlying these processes is the same. Using evolution we can understand how organisms generally change their stores of genetic information (DNA and RNA), alter their observable characteristics, and diversify.

We do not understand how cultures evolve nearly so well. The majority of human evolution does not involve changes in our DNA, but rather alterations in the gigantic library of nongenetic information, the culture, that our species possesses. This library is orders of magnitude larger than that of our genetic information, and the elements on its diverse shelves usually have meaning only in connection with other elements. Indeed, there has been a long, bitter debate about whether it is sensible even to use the term evolution to describe changes in culture
