The Moroccan Ministry of Culture has a press release (in French) about the cave site of Ifri n’Ammar, about 50km south (i.e., away from the coast) of Nador, indicating that the Moroccan-German team that has been working there for the past seven years has identified Aterian levels dating to about 175,000 BP. If these dates are correct, they push back the age for the earliest Aterian assemblages by some 65,000 year, since to date, the oldest Aterian levels had been identified at the Moroccan site of Dar es-Soltan, where they date to as old as 110,000 BP (Barton et al. 2009) . This is significant in and of itself by showing that the Aterian industry may be much longer than had previously been believed. And based on the press release, the Ifri n’Ammar does look very credibly Aterian, whose stone tool technology is generally defined by the presence of distinctive 'tanged' artifacts, especially points:© Moroccan Ministry of Culture. This is also significant because of what the Aterian is usually taken to mean in terms of prehistoric human adaptations. For some, it is associated with some of the earliest evidence for projectile technology, which confers the advantage of allowing prey to be brought down at a distance, hence minimizing the risks of hunting to whoever uses it (e.g., Shea 2006). Other researchers have also argued that some of the bifacial points associated with the Aterian "may be adaptive systems focused on hunting in grassland ecosystems" (Banks et al. 2006: 76, 78). Specifically, these authors have argued that such grassland ecosystems are established in North Africa (where the Aterian is found) beginning with Oxygen Isotope 5e, some 130,000 years ago, while before that bifacial lanceolate points are mostly found clustered much further to the SW. if the ages from Ifri n’Ammar are correct, then, this provides some evidence against a simple link between ecology and the emergence of the Aterian industry.Also of interest is that the Aterian sequence at Ifri n’Ammar is reported to be some 6.3m thick, with much more recent Aterian levels as well. Here, it bears emphasizing that Aterian deposits about 82,000 years old elsewhere in Morocco, have been associated with pierced shells most likely used as personal ornaments, the earliest evidence for that behavior anywhere in the world (as I discussed previously on this blog). It is perhaps not surprising, then, that the site has yielded in more recent levels"two Nassarius gibbosulus et Nassarius sp. shells used as ornaments by the Aterians. They are older than 80,000 years BP. Both are similar in size and display identical intentional perforations. Microscopic and mineralogical analyses have revealed wear traces clearly resulting from their having being worn as ornaments, and traces of red ochre with which they had been intentionally covered" (my translation). Pierced Nassarius shells from Ifri n’Ammar. © Moroccan Ministry of Culture. Overall,if the preliminary findings reported in this press release are borne out by future publications, Ifri n’Ammar definitely looks like it offers the potential to greatly refine our understanding of the Aterian and its origins as a whole.References:Banks, William E., Francesco d'Errico, Harold L.

Let me tell you a little story. When I was born my parents had two cats. One was named Garfield. The other...well, I don't remember what the other one was called. Not long after I was born, and little Jason was coughing up furballs, the doctors informed the parents that their little bundle of skin and hair was allergic to cats. It was then that teams were picked and lines were drawn. It was me or the cats. Luckily, the parents decided to keep me, and lose the cats. Imagine how much it would have sucked if they decided to keep the cats and lose me. I imagine if my younger brother had actually been my OLDER brother, he might have lobbied for the cats.
Figure 1: I like to imagine that the cats were not happy about this, and decided to wage eternal war.
And despite losing the battle of who got to live with the Mommy and Daddy Goldman, I think the cats are still trying to win the war. The thing is, I'd like to make peace with the cats. But every time I go near a cat, my eyes water, my throat gets all scratchy, I start sneezing. It's really pretty unpleasant. I once worked at a beautiful conference center near Los Angeles. And some very kind person had decided to donate their used couches to the institute. The couches were very comfortable, and so I decided to take a nap on one of them, one day. Within minutes, the all too familiar eye-watering and throat-scratching began. And I thought to myself: "these people had cats." How thoughtless of them to have donated their couches without at least having them cleaned. Or at least a minimal vacuuming. And then, I thought to myself: "evil cats probably orchestrated the whole thing!"
So, dear reader, it's not that I think cats are bad, per se. It's that cats have decided to wage holy war on me, for ousting them from their former place of reverence. And that is seriously bad times.
But because I love my readers more than I loathe cats, I set out today to learn some things about cat cognition. I spent two hours at a cafe (with poor service, good coffee, and free wifi) crawling through PubMed, Google Scholar, JSTOR, Web of Science...to no avail! And I think the reason I wasn't able to find very much on cat cognition is because...there aren't very many people studying cat cognition in the first place! Sure, I found a random study here and there, but nothing particularly interesting. No titles or abstracts that made me think "wow, this is really interesting." No extended lines of research.
And that got me thinking. Why were cats domesticated in the first place? And how? Read the rest of this post... | Read the comments on this post...... Read more »

There are about 1.5 million scholarly articles published in all the sciences, spread over about 24,000 journals. Even if there were a single database or entry-point providing access to all the literature, nobody would be able to keep up with everything that is being published in their field of work any more. Desperately looking for some clue as to which publications to select for in-depth reading and which to ignore, scientists began to rank the journals according to how often the articles in these journals were cited. This ranking got started around the 1960s, when the number of journals started to proliferate. Fast-forward to today: What began as a last-ditch effort to handle an overwhelming flood of scientific information is now a full blown business. Journal ranking by citations is now done commercially by a multi-billion Dollar media corporation, Thomson Reuters. The journal rankings are sold to research institutions on a subscription basis ranging anywhere between approx. 30,000-300,000€ (US$40,000-400,000) annually.With increased visibility for the high-ranking journals came an increase in submitted contributions. The higher ranking the journal, the more readers and contributors, so the more income for the publisher. And so the vicious cycle of scientific publishing evolved: more and more scientists want to publish in and read the high-ranking journals. Due to the high volume of submissions, the publishers of these journals are in a position to pick about 2-5% of the submitted articles for publication and reject the rest, increasing the prestige of these journals even more. Sometimes these rejections are accompanied by a recommendation to submit the work to one of the lower-rank journals of the same publisher. Clearly, something has to be exceptionally 'good' to make it into a high-ranking journal (or, as some claim, have the potential to increase the journal's rank). After a few cycles, it became difficult to distinguish if a scientific finding was so 'good' that it made it into the high-ranking journals or if it had to be good because it was published there. Indeed, for some aspects of scientific life such as promotions, hiring, grant proposals or other sorts of evaluations, this question wasn't even asked anymore. Publication quality became synonymous with journal rank. Today, where a scientist has published is often more important than what was published. In all human life, scarcity and branding are two powerful factors for determining value, as I'm sure any economist can tell a story or two about. Scientists are human beings and journal rank is but one example of just how prevalent the human factor is in the scientific enterprise. Today, the future of a professional scientist is all too often dominated more by the economics of scarcity and branding, rather than science.What does all that have to do with potatoes in France?After a discussion about potatoes over lunch the other day, I stumbled across this beautiful tale, published in 1956 in the American Potato Journal on how the potato arrived in France in the 18th century: This endorsement of the potato and that of the various potato dishes served at the King's table were enhanced by placing a uniformed guard on Parmentier's potato plot. Parmentier's considerate removal of the guard at night during the harvest season is reported to have furthered the success of the potato with the King's subjects. This story so reminded me of scientific publishing. Wikipedia puts the story a little more bluntly: Parmentier therefore began a series of publicity stunts for which he remains notable today, hosting dinners at which potato dishes featured prominently and guests included luminaries such as Benjamin Franklin and Antoine Lavoisier, giving bouquets of potato blossoms to the King and Queen, and surrounding his potato patch at Sablons with armed guards to suggest valuable goods — then instructed them to accept any and all bribes from civilians and withdrawing them at night so the greedy crowd could "steal" the potatoes. Now I wouldn't know anything about bribes, but the part about creating artificial scarcity and a brand name to increase value for an ordinary object rang familiar.In a recent 'Opinion' article in one of the journals at the very top of the rank, Nature, the author correctly points out that this system of journal rank has many flaws and should be replaced by a more scientific system for the metric evaluation of science. She specifically calls for social social scientists and economists to be involved in developing this new system, underscoring the points above. Indeed, it is remarkable that our current journal rank system is still in place. After all, not only does the author and many scientists agree, but also the originators of the journal rank system, the high-ranking journals themselves and even some evaluators all have long realized that using journal rank to evaluate individual researchers is both "unfair and unscholarly". I have lamented this absurd state of affairs plenty of times right here and elsewhere. However, artificial scarcity and brand name have, by now, developed such a powerful dynamic, fueled by billions in taxpayer money and a rich history of great scientific traditions, that it seems unstoppable, even if all participating parties agree that putting an end to it would be better for science.It is with these powerful dynamics (and some analogous evolutionary dynamics) in mind that I posted an off-hand comment to the 'Opinion' article mentioned above. The comment stated that any, even the most complex and scientifically tested system will eventually succumb to social dynamics adapting the scientific community to the system and maximizing the individual participant's benefit while minimizing their costs. The only system that would be immune to such dynamics is one where the rules change more quickly than the social dynamics can follow:Wouldn't it be nice if metrics weren't needed? However, despite all the justified objections to bibliometrics, unless we do something drastic to reduce research output to an amount manageable in the traditional way, we will not have any other choice than to use them.However, as the commenters before already mentioned, no matter how complex and sophisticated, any system is liable to gaming. Therefore, even in an ideal world where we had the most comprehensive and advanced system for reputation building and automated assessment of the huge scientific enterprise in all its diversity, wouldn't the evolutionary dynamics engaged by the selection pressures within such systems demand that we keep randomly shuffling the weights and rules of these future metrics faster than the population can adapt?This comment will soon be published as a 'Correspondence' piece in the printed version of Nature. I'll update the post with the direct link as soon as it is online.

A new study shows that chimps sacrifice their own advantage if they earned it unfairly.Image: Owen Booth / Creative Commons
Fairness is the basis of the social contract. As citizens we expect that when we contribute our fair share we should receive our just reward. When social benefits are handed out unequally or when prior agreements are not honored it represents a breach of trust. Based on this, Americans were justifiably outraged when, not just one, but two administrations bailed out the wealthiest institutions in the country while tens of thousands of homeowners (many of whom were victims of these same institutions) were evicted and left stranded. It smacked of favoritism, the corruption of politics by corporate money, and it was also just plain unfair. But isn't that the way the world works? Isn't it true, as we were so often told as children, that life is unfair?
The American financial tycoon Andrew Carnegie certainly thought so and today's economic elite have followed his example. In 1889 he used a perverted form of Darwinism to argue for a "law of competition" that became the cornerstone of his economic vision. His was a world in which might made right and where being too big to fail wasn't a liability, it was the key to success. In his Gospel of Wealth, Carnegie wrote that this natural law might be hard for the least among us but "it ensures the survival of the fittest in every department."
We accept and welcome therefore, as conditions to which we must accommodate ourselves, great inequality of environment, the concentration of business, industrial and commercial, in the hands of a few, and the law of competition between these, as being not only beneficial, but essential for the future progress of the race.
In other words, his answer was yes. Life is unfair and we'd better get used to it, social contract or no social contract.
While this perspective may be common among those primates who live in the concrete jungle of Wall Street, it doesn't hold true for the natural world more generally. Darwin understood that competition was an important factor in evolution, but it wasn't the only factor. Cooperation, sympathy, and fairness were equally important features in his vision for the evolution of life. In The Descent of Man he wrote that "Those communities which included the greatest number of the most sympathetic members would flourish best, and rear the greatest number of offspring." By working cooperatively, by sharing resources fairly, and by ensuring that all members of society benefited, Darwin argued that early human societies would be more "fit" than those societies where members only cared about themselves. The Russian naturalist Peter Kropotkin championed this aspect of Darwin's work and argued that mutual aid was essential for understanding the evolution of social mammals as a whole. In the time of Darwin and Kropotkin the research needed to verify these claims was in its infancy, but recent work has supported this vision of the natural world. Now, a new study has added one more plank to this growing edifice of knowledge, and the view from on top suggests that life, in contrast to what Carnegie believed, may not be so unfair after all.

A new fMRI study in PLoS reports Differential Brain Activation to Angry Faces by Elite Warfighters, the elite warfighters being US Navy SEALs.SEALs are indeed pretty elite. This being a British blog, I wouldn't want to say that they're the world's elitest naval special forces unit. That's the British Special Boat Service. But they could still kill you ten times before you knew they were there (unless you're in the Special Boat Service.)Anyway, San Diego researchers Paulus et al scanned 11 SEALs and 23 healthy civilian men during an emotional face matching (originally developed by Hariri et al) that involved seeing happy, angry, and fearful faces.Such tasks are very popular in neuroimaging at the moment because looking at faces of people expressing strong emotions reliably activates emotion-related brain areas, without needing to actually induce emotions in your volunteers which can cause practical problems, i.e. people getting scared and maybe panicking in the MRI scanner. Whether studying emotional-face-induced activation is a valid substitute for studying emotion-induced activation is an open question.What happened? fMRI being a sensitive way of measuring human brain activation, they found some differences between the two groups in neural responses to seeing the faces:elite warfighters relative to comparison subjects showed relatively greater right-sided insula, but attenuated left-sided insula, activation. Second, these individuals showed selectively greater activation to angry target faces relative to fearful or happy target faces bilaterally in the insula.OK. So what does that mean?These findings support the notion that elite warfighters... deploy greater neural processing resources toward potential threat-related facial expressions and reduced processing resources to non-threat-related facial expressions. This finding suggests that rather than expending more effort in general, elite warfighters show more focused neural and performance tuning, such that greater neural processing resources are directed toward threat stimuli and processing resources are conserved when facing a nonthreat stimulus situation.So the message is that SEALs are better at focusing on threats and don't get distracted by benign background stuff. Although apparently this is only true of their insula, not an area known for its role in attention, and the threat was an angry face on a screen. But that aside, this is not very surprising given that they're highly-trained soldiers.But the unsurprisingness of this result is a problem. We don't need neuroscience to tell us that elite soldiers are good at detecting and responding to threats. That's rather obvious. I'd guess that most of them were pretty good at it before they got selected, and then they got even better with training. This must have something to do with the brain, because your brain is what allows you to learn stuff.What we don't understand very well yet is how training (or other forms of learning) works, on a neural level, i.e. what the molecular and cellular mechanisms are. It would be really nice to find out. Unfortunately, fMRI studies like this are unable to tell us that, because they only study the very last stage in the process, the final product.This is in no way a problem with this paper alone, and it's no worse than many other articles. The same issue applies to many neuroimaging studies of abnormal states like depression or, as I've posted about previously, psychological trauma. Such results can form the basis for investigations into mechanisms, and as ways of testing theories, but on their own, finding that abnormal brains react in abnormal ways is not, in itself, very useful.Paulus, M., Simmons, A., Fitzpatrick, S., Potterat, E., Van Orden, K., Bauman, J., & Swain, J.
