I have long maintained that the religious impulse is a core part of our evolutionary biology, because every human being I have ever known is religious about something.
Even—and especially—the unreligious, who will not realize they are in the throes of it because they may define religion as “believing in something for no reason at all”, rather than a rational faith that asks questions, observes data, records answers, and believes on the strength of the evidence that it has thus far.
Given that every known human civilization has objects of affection, inspiration and veneration, it is not surprising to see that religiosity extends into the secular realm and may even be actively cultivated by savvy marketing.
Just as the Genius Bar has proved to be genius, the now-classic Apple slogan “Think Different” also turns out to be more than just words: The brains of Apple fans really are different. When Martin Lindstrom, a brand consultant and author of Buyology: The Truth and Lies About Why We Buy, examined those brains under a functional magnetic-resonance-imaging scanner, he discovered that Apple devotees are indistinguishable from those committed to Jesus. “Apple’s brand is so powerful that for some people it’s just like a true religion,” Lindstrom says.
Apple cultivates religious fervor among its adherents in a number of subtle ways, including its mysteriousness and its suggestion that customers are among the chosen ones. Perhaps most important, though, is Apple’s devotion to symbology. Its most effective marketing efforts, Lindstrom says, are built into the products themselves. Think of the iPod’s white earbuds, the Mac’s startup sound, or the unmistakable shape of the MacBook’s back panel. None of these choices were accidental. Apple understands the lasting power of sensory cues, and it goes out of its way to infuse everything it makes with memorable ideas that scream its brand.

It would be easy to go for the cheap laugh and say “See? It is a cult!” But I think the story reinforces a broader truth about human nature.
My sense is that asking humans to not indulge their religious nature is akin to asking sharks not to swim or eat seals. When people draw pleasure and inspiration from something—be it a relationship with the Creator of the universe or merely Apple Inc. of Cupertino—they will continue to seek out that experience and strengthen that bond.
One hopes that those who experience their religion as a purely secular phenomena can have some understanding of what draws believers back to churches and hymns week after week.

Adventurer archetype Carl Akeley (1864-1926) was an exceedingly productive taxidermist, sculptor, explorer and inventor. His interest in ornithology begat a need to preserve specimens, so young Akeley read up on the subject and taught himself the basics of taxidermy. He subsequently landed a job with science education supplier Ward’s Natural Science Establishment, then further refined his craft in jobs with a series of increasingly prominent museums.
Hearing of his achievements the British Museum in London offered him a position, but on his way, he stopped in Chicago where he was enticed to join their Field Museum of Natural History instead. Winning Carl over by the promise of African travel, he led two major expeditions while in their employment, the first in 1896 and later in 1905.

Chicago’s Field Museum has posted 136 of Akeley’s hand-coloured slides and black-and-white photographs to Flickr, a selection of which I have excerpted below. See their Africa Expeditions set for more.
Akeley died during his fifth and final African expedition, and is buried in Albert (now Virunga) National Park. He left behind an enormous and meticulously catalogued collection of specimens—his crowning achievement. Today, three-quarters of a century after it was first opened to the public, that collection of 28 stunning dioramas continues to amaze visitors to the American Museum of Natural History.
In total, Carl launched five collecting trips to the African subcontinent, joining Theodore Roosevelt on his 1909 expedition while he was working for the American Museum of Natural History in New York. Filmed by Cherry Kearton for the feature, With Roosevelt in Africa (1910) it also provided many specimens still on display in the museum in a wing named in Carl’s honour – the Akeley Hall of African Mammals.

Freed from an icy grave after almost a century, parts of the first aircraft taken to Antarctica—also the very first aircraft produced by Britain’s Vickers factory—have been located in Cape Denison, Commonwealth Bay.
Australian geologist Sir Douglas Mawson had planned to conduct an aerial survey as part of his 1911-1914 Australasian Antarctic Expedition, but the plan was scuttled when the aircraft’s wings were damaged in an October 1911 demonstration flight. Mawson had no time to repair the aircraft prior to departure, so he ordered his electrical engineer/motor expert, Francis H. Bickerton, to remove the wings and convert it into an “air-tractor”—essentially a propeller-powered sled—to haul supplies. After hauling gear across a plateau for sixteen kilometres, the engine could not cope with the extreme cold and quit. The aircraft was eventually hauled back to the encampment and abandoned. When Mawson returned to Australia, the engine was returned to Vickers in the UK to help pay down debts; the rest of the fuselage frame was left behind at Cape Denison, and was visible up to the mid-1970s when it was presumed to have been swallowed by the ice.
The aircraft was found on New Year’s Day by a team of Australians dedicated to preserving the site of Mawson’s first Antarctic encampment.
AN HISTORIC monoplane – a relic of Sir Douglas Mawson’s 1911-14 expedition – has been found in Antarctica thanks to freakish luck after a three-year search.
An Australian heritage carpenter stumbled on the remains of the craft – the first Vickers aircraft ever made – on New Year’s Day at Cape Denison.
The cast iron framework of the plane was revealed by an unusually low tide and reduced ice cover.
“It’s a remarkable find in remarkable circumstances,” chairman of the Mawson’s Huts Foundation David Jensen said.
“We began the search three summers ago and thought we might have a reasonable chance of finding it with all the equipment provided to us by sponsors.”
Nearly a century after it was abandoned by Mawson, the old Vickers was spotted sitting among rocks in a few centimetres of water during one of the lowest tides recorded at Commonwealth Bay.
“They would not have been found had the tide not been so low and the ice cover at Cape Denison at its lowest for several years – it was a fluke find,” Mr Jensen said in a statement.

The Vickers REP monoplane was designed in France by Robert Esnault-Pelterie (hence REP), but built by Vickers in Britain.
There is also a slight Canadian connection, since the Oxford-born engineer Bickerton made his home in Newfoundland during the Roating Twenties. He is reported to have travelled between that colony and Britain quite frequently, easily shifting gears between the lifestyles of a New World outdoorsman and a fashionable London partygoer and man-about-town.
For more information on the finding of the aircraft—and the current state of the Mawson huts in general—the Expedition Blog of the Mawson’s Hut Foundation is probably the best source (especially these posts; 1, 2).
The State Library of New South Wales has posted a collection of images taken by photographer Frank Hurley during Australia’s first tentative explorations of the planet’s ice-bound southern continent.
Students of polar history will know that Mr. Hurley and several other AAE members would go on to greater fame for their perseverance in Sir Ernest Shackleton’s ill-fated Imperial Trans-Antarctic Expedition (1914-1916); not to mention service in the Great War.

- Palaeontologists have discovered a “missing link” between early and late pterosaurs; an animal which combines some of the notable features of each. Dubbed darwinopterus (or “Darwin’s wing”), it features “a tail and hind legs like the older pterosaurs, but pointy teeth and a head/neck shape both almost identical to later species.” It bolsters support for the theory of modular evolution—that the evolutionary process assembles new genes from copies of pieces of various older genes, rapidly building new features and functions from a new arrangement of already reliable parts. Abstract from the Proceedings of the Royal Society (Biological Sciences) available here.
- Generally regarded as the archetypal early bird, archaeopteryx (Greek for “ancient wing”) has been found to be much more like its slow-growing land-bound cousins, lacking the rapid bone growth common to all current-day birds (who grow and mature in a matter of weeks). Microscopic analysis of fossilised archaeopteryx cells and blood vessels indicate that it took several years to grow from juvenile to adult. In the words of lead paleobiologist Greg Erickson, “We learned that the adult would have been raven-sized and taken about 970 days to mature. Some same-size birds today can do likewise in eight or nine weeks. In contrast, maximal growth rates for Archaeopteryx resemble dinosaur rates, which are three times slower than living birds and four times faster than living reptiles.” Abstract from the Public Library of Science (PLoS ONE) available here.
- One-third of the dinosaur species currently identified may not have existed, because they are actually juvenile forms of other species and not a separate species in their own right.
- In 1863, a family of Virginia palaeontologists discovered a hidden valley of living dinosaurs; the Union Army attempted to weaponise them into tools of mass mayhem and destruction against the secessionist South.

Ethiopian paleoanthropologist Yohannes Haile-Selassie has discovered an interesting biological clue about our hominid ancestors. They lacked a few of the traits that we associate with modern day ape-ness:
The story of Ardi takes us back 4.4 million years to a corner of northeast Ethiopia that today is a desert where erosion constantly exposes fossils from the dawn of humankind.
In all, scientists have discovered fossilized bones and teeth in the area representing three dozen individual Ardipithecus specimens, including much of Ardi’s skull, pelvis, lower arms and feet. Until now, Haile-Selassie says, much of what we knew about our ancient past derived from comparisons with the other apes, and especially chimps, and from Ardi’s younger ‘sister’ — Lucy, the 3.2-million-year-old specimen of another hominid species, Australopithecus afarensis, discovered in 1974, also in Ethiopia. Lucy’s discovery showed that human forebears walked upright that long ago.
But Ardi, Haile-Selassie says, shows our first erect steps took place more than a million years earlier and that is much closer to the last common ancestor (or LCA) that the human line shares with the ape line after the two split some six million years ago.
Until now, it has been assumed chimps and gorillas have retained many of the supposed traits of that last common ancestor, among them knuckle-walking and climbing ability.
Now, Haile-Selassie says, we know that isn’t true.
Ardi shows that unlike modern apes, which are knuckle-walkers, her species — and by extension all the ancestors of all apes and humans — descended from a common ancestor that in turn was not a knuckle-walker, he says.
…The researchers say the surprising findings mean chimps and gorillas have specialized greatly since then and are poor models for a common ancestor and for understanding human abilities such as walking.

This further underlines the somewhat little-understood distinction that humanity is not descended from “monkeys”, but that apes and humans shared a common ancestor. It’s a big difference, and it’s important to remember that a lot of the ape traits that we see today actually evolved long after our developmental paths began to diverge. So while we can learn something from our modern simian relatives, they offer limited utility in understanding how we developed the unique capabilities that make us Homo sapiens. For that we have to go to the fossil record and continue to mine our own history.
Our planet’s most southerly continent is notionally one of those awe-inspiring places I would like to visit. At least for a couple of hours. Ideally it would be as one of those C17 aircrews that flies in a load of gear and people, then jets right back out an hour later.
Of course there is the incredible visual poetry of the place, which is no doubt part of the enchantment that drove such as Amundsen, Scott and Shackleton to hazard their lives in exploration of it.
But it’s not all sweetness and light. The weather has rough days.
And so does the sea, too.
Health Canada microbiologists confirm that the Mexican, American and Canadian variants of the swine flu are all the same strain:
Canadian scientists who sequenced Canadian and Mexican samples of the swine flu virus say it is the same strain, even though the virus seems to cause more severe symptoms in Mexico.
Scientists at Health Canada’s National Microbiology Laboratory in Winnipeg genetically sequenced and compared samples of the H1N1 flu virus from Nova Scotia, Ontario and Mexico. It’s the first time the sequence has been completed on samples from Mexico and Canada, said officials during a news conference in Ottawa Wednesday.
The results have ruled out a mutation to explain why the Mexican cases have been much more severe than elsewhere, said Dr. Frank Plummer, the chief science adviser of the national lab.
“Essentially, what it appears to suggest, is that there is nothing at the genetic level that differentiates this virus that we got from Mexico and those from Nova Scotia and Ontario, that explains apparent differences in disease severity between Mexico and Canada and the United States,” said Plummer.

So what makes it so deadly in Mexico? Pre-existing medical conditions? Environmental stimulus? Genetic predisposition? Quality of care?
