The passion of flying

Another gem from Capt. Bob.

Many of you will have watched the video of the dolphins being rescued off a Brazilian beach that I published a week ago under the title of Wet eyes warning.  That was sent to me by Capt. Bob.  Bob, like my son, is a commercial airline captain.

Now Bob has sent me this.  Some day, I’ll natter on about my own amateur love affair with flying, both gliding (sailplane in USA speak) and power.  But for now just marvel at the skills on display as in the name of fire control these crews quite deliberately do all the things that most would consider suicidal in aviation affairs.

The power of consequences

That unwritten law of the power of unintended consequences strikes again.

Before moving on to today’s post, just wanted to say that our recent move to Merlin, Oregon continues to take up huge (and enjoyable) demands on our time so the opportunity to write lengthy posts on Learning from Dogs is still some way off.  Having said that with the quality of analysis that is available from others, some readers may prefer it as it currently is!

There is no better example of this than the post that follows.  It is from the blog site of Peter Sinclair ‘Climate Crocks‘.  As the ‘About‘ page says,

Peter Sinclair is a long time advocate of environmental awareness and energy alternatives. An award winning graphic artist, illustrator, and animator, Mr. Sinclair runs Greenman Studio from his home in Midland, MI.

Mr. Sinclair’s syndicated cartoons have appeared worldwide, and his work has been profiled in numerous publications, including the New York Times.  He is the producer of the YouTube series, “Climate Denial Crock of the Week”.

A couple of days ago, Peter published a post called, ““La La La I Can’t Hear You” Comes Home to Haunt GOP, in the Election, and on Climate”. I read it with interest and asked Peter if I might republish it.  In a matter of moments, I received a reply giving me such permission; here it is.

When Al Jazeera and The American Conservative are in agreement that you have a problem, you probably have a problem.

The American Conservative:

But the problem wasn’t just that conservative media gave Romney supporters bad information. The people in conservative media also seem to have been fully taken in by the idea that Romney would win and would do so in decisive fashion, and the campaign came to believe its own propaganda, too. As York notes, Romney didn’t have a prepared concession speech. It apparently never occurred to his campaign that he would lose. That’s not so remarkable by itself, but it is just one part of the overall pattern of the Romney campaign and the conservative movement’s reaction to Obama. Romney spent years running against a fantasy record and campaigning on a series of gross distortions and falsehoods, and so it shouldn’t be too surprising that his campaign and his conservative media boosters didn’t have the firmest grip on political reality.

Al Jazeera:

After the election, a number of different people tweeted about a rather obvious connection – how the same people who didn’t believe the polls don’t believe global warming, either. There’s a further correlation here: On the polling side, the supposedly most liberally-biased pollsters actually came closest to hitting the mark, both in the Fordham analysis of national polls and a more sophisticated analysis of state polls by Emory political scientist Drew Linzer at his Votamatic website.

On the global warming side, a new study comparing climate models finds that those predicting the largest climate impacts by 2100 are the most accurate in modelling climate change that’s already occurred – specifically, humidity levels related to cloud formation. In short, the reality being denied in both cases is even worse than it first appears, so attempts to “compromise” or give conservatives “the benefit of the doubt” actually lead us further astray (since I first wrote this, David Roberts of Grist has written an excellent comparison of the twin delusions).

But there is more than just a correlation here. There is a common causal factor involved: Conservatives, trusting their guts, have created their own separate reality, with their own authorities, and their reasoning dominated by ideology, where certain sorts of facts simply cannot intrude. Election day was one of those rare moments in which the bubble they live inside collapsed.

Dave Roberts in Grist:

In the face of model projections like Silver’s, Jonah Goldberg said that “the soul … is not so easily number-crunched.” David Brooks warnedthat “experts with fancy computer models are terrible at predicting human behavior.” Joe Scarborough said “anybody that thinks that this race is anything but a tossup right now is such an ideologue.” Peggy Noonan said that “the vibrations are right” for a Romney win. All sorts of conservative pundits were convinced the Romney campaign just felt like a winner.

Empiricism won. It didn’t win because it’s a truer faith or a superior ideology. It won because it works. It is the best way humans have figured out to set aside their perceptual limitations and cognitive shortcomings, to get a clear view of what’s happening and what’s to come.

As it happens, there’s another issue in American politics where empiricists are forecasting the future and being ignored. Here’s what the Nate Silvers of climate science are up to:

Looking back at 10 years of atmospheric humidity data from NASA satellites, [John Fasullo and Kevin Trenberth of the National Center for Atmospheric Research] examined two dozen of the world’s most sophisticated climate simulations. They found the simulations that most closely matched actual humidity measurements were also the ones that predicted the most extreme global warming.

In other words, by using real data, the scientists picked simulation winners and losers.

“The models at the higher end of temperature predictions uniformly did a better job,” Fasullo said. The simulations that fared worse — the ones predicting smaller temperature rises — “should be outright discounted,” he added.

The Washington Post spells out what that means:

That means the world could be in for a devastating increase of about eight degrees Fahrenheit by 2100, resulting in drastically higher seas, disappearing coastlines and more severe droughts, floods and other destructive weather.

Just reread that last paragraph a couple of times – and make a promise to yourself, and those loved ones around you, to make a positive difference starting now.  And subscribe to Peter’s blogsite!

Animals in love

The beautiful hidden depths of the consciousness of animals

Back in the Summer of 2011, I published a couple of posts on the subject of consciousness.  The first one was called Consciousness, science or God? and the second one about a month later continued the theme under the heading of And more on consciousness.

In that second article, I concluded with these words:

Finally, do you have a dog at home?  If you do, ponder on how their conscious world engages them.  If science can’t explain human consciousness then all we have is our own intuition with regard to animals.  Not sure about you but when one is feeling a little low and a dog comes up and lays a head across you I feel a very strong conscious connection.

Hazel and Pharaoh

The dog to the left of Pharaoh in the above picture is Hazel.  Shortly before we left San Carlos, Mexico to move up to Arizona in February, 2010, this dog was dumped outside Jean’s house.  She was still in milk and Jean explained that it was common practice for female dogs to be cast out shortly after they had had pups.  The pups would have been sold for a few pesos and the mother dog was no longer of any use or value and was ‘disposed’.

We took her in, of course, and she joined the other dozen dogs on our journey to our new Arizonan home.  Hazel has the sweetest of dispositions and frequently sleeps snuggled up against me at night.  As I write these words, Hazel is sleeping just to the left of my feet.  There are times when Hazel looks into my eyes with what I can’t lable as anything other than the look of a dog in love.

So with that in mind, let me introduce you to Kate and Pippin.  As their website proposes  Kate & Pippin is “An unlikely love story“.

THE STORY

Pippin, a helpless baby fawn was abandoned by her mother on the property of Isobel Springett. Isobel’s Great Dane, Kate, adopted Pippin immediately and they have been best friends ever since.

The story of Kate’s and Pippin’s loving relationship is charmingly chronicled in a handsome book featuring the beautiful photography of Isobel Springett.

Here’s Martin Springett, author of the book.

While there’s a small degree of overlap with the first video, you’ll still love to watch this.

A collection of photos from pips’s early days. She was just a few days old when she found us. Music is by my brother Martin Springett.

To close, here’s Pip at about two and a half months old. She’s just lost her spots and is looking like a teenager, all legs! She loves grapes and bananas after her bottle. (And the music is fabulous – Artist: Jelengue “Amar Mi Verdad”)

Reminds me of that great book from Jeffrey Masson, Dogs never lie about love!

Wet eyes warning!

Sent to me by Capt. Bob D., whom I have known for many years.

The video has been widely published on many blogs but so what!  It involves a school of dolphins becoming stuck on the beach in Brazil and they get rescued by a group of upstanding citizens.  Just 4 minutes long but not short on displaying the love man has for these wonderful animals.  Would be nice if we held all animals with equal esteem.

A damming indictment!

Life’s strange quirks.

I’m very grateful to John H., a dear friend back in Payson, for forwarding this to me.  Enjoy!

oooOOOooo

This is an actual letter sent to a man named Ryan DeVries regarding a pond on his property. It was sent by the Pennsylvania Department of Environmental Quality, State of Pennsylvania . This guy’s response is hilarious, but read the State’s letter before you get to the response letter, you won’t stop once you start. WOW Love this man.

——————-

This is an actual letter: State of Pennsylvania’s letter to Mr. DeVries: 

SUBJECT: DEQ …. File No.97-59-0023; T11N; R10W, Sec 20; Lycoming County

Dear Mr. DeVries:

It has come to the attention of the Department of Environmental Quality that there has been recent unauthorized activity on the above referenced parcel of property. You have been certified as the legal landowner and/or contractor who did the following unauthorized activity:

Construction and maintenance of two wood debris dams across the outlet stream of Spring Pond.

A permit must be issued prior to the start of this type of activity. A review of the Department’s files shows that no permits have been issued Therefore, the Department has determined that this activity is in violation of Part 301, Inland Lakes and Streams, of the Natural Resource and Environmental Protection Act, Act 451 of the Public Acts of 1994, being sections 324.30101 to 324.30113 of the Pennsylvania Compiled Laws, annotated.

The Department has been informed that one or both of the dams partially failed during a recent rain event, causing debris and flooding at downstream locations.. We find that dams of this nature are inherently hazardous and cannot be permitted. The Department therefore orders you to cease and desist all activities at this location, and to restore the stream to a free-flow condition by removing all wood and brush forming the dams from the stream channel. All restoration work shall be completed no later than January 31, 2010.

Please notify this office when the restoration has been completed so that a follow-up site inspection may be scheduled by our staff. Failure to comply with this request or any further unauthorized activity on the site may result in this case being referred for elevated enforcement action..

We anticipate and would appreciate your full cooperation in this matter. Please feel free to contact me at this office if you have any questions.

Sincerely,

David L. Price
District Representative and Water Management Division.

Here is the actual response sent back by Mr. DeVries: 

Re: DEQ File
No.. 97-59-0023; T11N; R10W, Sec. 20; Lycoming County

Dear Mr. Price,

Your certified letter dated 11/17/09 has been handed to me. I am the legal landowner but not the Contractor at 2088 Dagget Lane , Trout Run, Pennsylvania .

A couple of beavers are in the process of constructing and maintaining two wood ‘debris’ dams across the outlet stream of my Spring Pond. While I did not pay for, authorize, nor supervise their dam project, I think they would be highly offended that you call their skillful use of natures building materials ‘debris.’

I would like to challenge your department to attempt to emulate their dam project any time and/or any place you choose. I believe I can safely state there is no way you could ever match their dam skills, their dam resourcefulness, their dam ingenuity, their dam persistence, their dam determination and/or their dam work ethic.

These are the beavers/contractors you are seeking. As to your request, I do not think the beavers are aware that they must first fill out a dam permit prior to the start of this type of dam activity.

My first dam question to you is:
(1) Are you trying to discriminate against my Spring Pond Beavers, or
(2) Do you require all beavers throughout this State to conform to said dam request?

If you are not discriminating against these particular beavers, through the Freedom of Information Act, I request completed copies of all those other applicable beaver dam permits that have been issued. (Perhaps we will see if there really is a dam violation of Part 301, Inland Lakes and Streams, of the Natural Resource and Environmental Protection Act, Act 451 of the Public Acts of 1994, being sections 324.30101 to 324.30113 of the Pennsylvania Compiled Laws, annotated.)

I have several dam concerns. My first dam concern is, aren’t the beavers entitled to legal representation? The Spring Pond Beavers are financially destitute and are unable to pay for said representation — so the State will have to provide them with a dam lawyer.

The Department’s dam concern that either one or both of the dams failed during a recent rain event, causing flooding, is proof that this is a natural occurrence, which the Department is required to protect. In other words, we should leave the Spring Pond Beavers alone rather than harassing them and calling them dam names.

If you want the dammed stream ‘restored’ to a dam free-flow condition please contact the beavers — but if you are going to arrest them, they obviously did not pay any attention to your dam letter, they being unable to read English.

In my humble opinion, the Spring Pond Beavers have a right to build their unauthorized dams as long as the sky is blue, the grass is green and water flows downstream. They have more dam rights than I do to live and enjoy Spring Pond. If the Department of Natural Resources and Environmental Protection lives up to its name, it should protect the natural resources (Beavers) and the environment (Beavers’ Dams).

So, as far as the beavers and I are concerned, this dam case can be referred for more elevated enforcement action right now. Why wait until 1/31/2010? The Spring Pond Beavers may be under the dam ice by then and there will be no way for you or your dam staff to contact/harass them.

In conclusion, I would like to bring to your attention to a real environmental quality, health, problem in the area It is the bears! Bears are actually defecating in our woods. I definitely believe you should be persecuting the defecating bears and leave the beavers alone. If you are going to investigate the beaver dam, watch your dam step! The bears are not careful where they dump!

Being unable to comply with your dam request, and being unable to contact you on your dam answering machine, I am sending this response to your dam office.

THANK YOU,

RYAN DEVRIES & THE DAM BEAVERS

oooOOOooo

Those dam beavers!

Postscript to the result

Will we see the renewed President Obama take notice of what we are doing to the planet?

But don’t hold your breath! The BBC reported that President Obama in his victory speech had “pledged to work with Republican leaders in Congress to reduce the government’s budget deficit, fix the tax code and reform the immigration system.”  All well and dandy but, perhaps, missing the big one – climate change.

OK, on to the meat of this post.

“Frankenstorm”

I first came across this reflection on Hurricane Sandy in Christine’s great blog 350 or bust.  It’s an essay written by Colin Beavan, aka “No Impact Man“, who lives in New York City and wrote a response after experiencing Hurricane Sandy last week.  I then asked Colin if I could republish his essay on Learning from Dogs and promptly received his approval.

What to do if Hurricane Sandy scared you

Dear friends,

I don’t say this often but I am scared. Not scared to the point of paralysis. Not scared enough to run away. Not scared enough to stop trying to help. Not scared enough to think we’re doomed. Just scared enough to feel worried for myself, my family, my friends, my community, my country, and my world.

I was lucky when Hurricane Sandy hit. My daughter Bella and I put on our waterproofs in the early hours and ran around Brooklyn’s Fort Greene park in the wind and rain with Frankie–our dog–and our Occupy Wall Street activist friend/hero Monica Hunken.

That night, the lights flickered a couple of times. I lost my internet for three hours. Frankie the dog hid in the upstairs bathroom bathtub. That was the extent of it.

But when I woke up, lower Manhattan was flooded and without power. All the coastal parts of Brooklyn and Queens from Red Hook to Coney Island through the Rockaways and Hamilton Beach were hammered. The wind had driven a fire through Queens that destroyed so many houses. And the world’s most amazing subway system was brought to its knees. To say nothing of poor Staten Island and coastal New Jersey.

We in the Tri-State Area didn’t get Katrina. But we got a taste of her.

Yes, there are some good parts. New Yorkers have been showing up some of the emergency shelters in such numbers that they have been turned away. There are donation drives and volunteer efforts. And about a gazillion New Yorkers have taken to cycling.

But there is a lot of suffering. And a lot of fear not of what Sandy brought. But of what next year’s storm will bring. And the year after that. And after that. First Irene, now Sandy, for how many years in a row can New York City withstand a “once in a century” storm, people are asking?

I hung up the phone with a friend just a few minutes ago. She said, “In some ways, this is way more scarey than 9/11, because you get the feeling that it could happen again and again and again.”

In a coffee shop this afternoon, everyone at every table was talking about climate change. People are talking about where they will go next time. To an aunt’s in New Hampshire. A friend with three cottages in Maine. People are talking about their escape plan for when New York stops functioning.

Katrina, Irene, Sandy, droughts all summer, busted corn crops, water shortages in the southwest: it’s hard to believe we aren’t seeing what the climate scientists predicted. But sooner. Way sooner than they said.

It feels ironic and sad. That the war in Iraq sparked by 9/11 may have got us what we wanted–control over more oil. But that burning that self-same oil has brought us another mini-9/11. Except that this one we are kind of doing to ourselves.

Fracking–the drilling for natural gas by injecting poisonous chemicals into the same rock formations that our drinking comes from. Fighting in the Middle East. Drilling in the arctic. Mountaintop removal in Appalachia. Mining the Canadian tar sands. Building the pipelines. This is bonkers.

Especially when the sun shines everywhere. The wind blows everywhere. The rivers run everywhere. We can generate our power in better, cheaper, safer ways.

Of course, there are reasons for resistance. Our economy is based on fossil fuels. Changing it would be a gargantuan effort. There would be a cost to a transition. But the costs of not making the transition will be much higher. Ask the NY Mass Transit Authority, which is still pumping out the tunnels. Or ask the citizens of New Orleans.

But this isn’t a bitch fest. It’s an appeal.

Years ago, when I did the No Impact Man experiment, I went on the Good Morning America show and I said it wasn’t important that all Americans did as much as I did. “We must each just do something,” I said.

I was mistaken. We must each do a lot.

We all–including me–have a tendency to think that shaking our fist at the TV news or leaving an angry comment on a blog or “clictivism” is some sort of an expression. We need to do more. Not just more at home, but more in our civic engagement, more in the citizen guiding of how our society moves forward.

In fact, I’d argue that we–all of us–need to find a way to dedicate at least some part of our lives to solving our problems. Climate change we need to fix, yes. But also we need to accept that the economic system we live in is driving that climate change. Consumption, as the basis for economy, has become like a winter coat that needs to be shed. It no longer serves us.

Now, I’m not going to claim that I know what each of us should do, how each of us should help to bring about the Great Transformation. I don’t think anyone exactly knows. This, by the way, was the great criticism of Occupy Wall Street, back in the day. That they didn’t say exactly what we should do. They didn’t make their demands clear, the press kept saying.

That was Occupy’s strength in my view. The willingness to bring attention to problems we don’t quite know the solutions for. Occupy didn’t have concrete demands because none of us quite know what we should be demanding quite yet. Occupy was saying “stop ignoring problems just because we don’t know the solution!!!!!!”

You may disagree with me. You may say, we know the solution, it’s renewable energy. But where is the political will to bring that change about when the fossil fuel industry has spent $150 million in this election cycle?

You may say, the solution is getting corporate money out of politics. But how do we do that when the politicians we need to vote for such a thing are the beneficiaries of that self-same corporate money?

You may say, the solution lies in measuring Gross National Happiness instead of Gross Domestic Product. But how do we get that done?

We have lots of ideas about what would fix things, but we have no idea how to actually get those ideas instituted. That’s kind of where we are at a loss. How do we actually bring about the change?

It’s not to say we can’t bring it about. But it is to say that a lot more of us are going to have to join the search for the solutions and the effort to institute them.

In a way, what I am saying is the same as what Occupy said: “Stop pretending that you can’t help just because you don’t know exactly how to help!!!!!!”

We all have to start dedicating some of our lives to these problems. Not just voting for the right people. Not just leaving comments on blogs. Not just having intense conversations over coffee.

So what then?

Here’s a thought. Decide to dedicate five to ten hours a week to helping figure out what to do. Then use those five to ten hours to bring your personal gifts to the search for societal solutions and the means of implementing them.

If you are political then, whatever side of the aisle you are on, start going to your party’s meetings and insist that they address themselves to the major, new-world problems we are facing instead of grumbling over the same stuff they have for 50 years. Get them to try to be leaders instead of winners.

If you are an artist or musician or writer, use your talents to bring more and more attention to our problems and the quest for the solution. Be a constant reminder of the peril our society and world faces.

If you are a therapist or life coach, find a way to introduce to your clients the idea that the problems they face are the same problems all of us are facing. Financial insecurity, for example, is something we can fix together better than any one of us can fix alone.

If you are a banker, bring your personal values and your heart and soul to work with you. The expression “it’s only business” has to be jettisoned. This idea that the free market will fix things so we can ignore the dictates of our conscience needs to be fixed.

If you have a spare bedroom, find an activist who can’t drag themselves away from the work they are doing for all of us long enough to earn themselves some rent. Home and safety for those on the front line of social change is a wonderful service.

If you have two feet, march with my friends at 350.org whenever you have a chance.

All of us have our own ways to help.

One thing is clear, whatever our individual contribution, every one of us needs to be moving back into the political system and the democracy. We are all so disgusted by it that our instinct is to abandon it. In this case, our instinct is wrong. We totally need to Occupy our democracy. We need to flood it with people, with us.

Overall, though, my point here is that all of us have a role to play in our cultural healing. There is no leader who can tell us how to contribute. Each of us has to look around us and use our own minds and souls to see what needs doing and how we are best suited to do it. Each of us must contribute in our own way.

I began this piece by saying that I’m scared. Because I am. But my fear is just a sign that I need to do something. There is really only one thing I know how to do–to write. And so I’m doing it. I don’t know if if will help. But it is the one thing I know how to do.

What is the one thing you know how to do? What is the one thing you can dedicate a slice of your life to?

We can’t leave it to the politicians or the designers or the Occupiers or the activists. It’s up to each of us.

Because–and I’ve said and written this many times–the question is not whether each of us is the type of person who can make a difference. The question is whether we are the type of people who want to try to make a difference. And Sandy has told us we all need each other to try.

Love,
Colin

Nothing much to argue about that! Thanks Colin for letting me republish your essay.

Reflections on an election

A personal perspective on today’s American presidential election

Voting for truth!

In many ways, it’s helpful that despite being a resident of the USA I am not eligible to vote.  That’s because my residency status as a ‘Green card’ holder does not give me such entitlement.  That’s the domain of citizens, and rightly so.

The reason I find it helpful is that as a non-voter and still very much the ‘newcomer’ to this county, I view the proceedings from a different perspective; well that’s my take on things!

So here are two thoughts.

Integrity

The motivation behind Learning from Dogs came from the realisation that dogs offer mankind many lessons, especially the one of behaving with integrity.  You can read more about this aspect of dogs here.

Maybe it’s a naive hope but politicians around the world must rapidly embrace the fact that without integrity in the political processes we are all lost.  To underline this plea, go and read a recent essay that was introduced by Daniel Honan on The Big Think. Here’s a dip into that:

Larry Lessig: End Raging Cronyism, Save Our Republic

What’s the Big Idea?

If you are not planning to vote in the upcoming election, Larry Lessig has a good explanation why.

You, like most Americans, believe that money buys results in Congress. No matter who wins, you believe that corporate interests will still have too much power and prevent real change. You are correct in your belief that money buys results in Congress, Lessig says. However, he has a different prescription than non-participation.

What’s the Significance?

Lessig points out that .000015 percent, or 47 individuals, have given 42 percent of the Super PAC donations this election cycle. As a result of this “money election,” Lessig says a few powerful interests exert an influence that conflicts with the public good.

… 47 individuals, have given 42 percent of the Super PAC donations this election cycle.”  Just reflect on the power and influence that flows from such a distortion of fairness.

Truthfulness

My second thought is about being truthful.

The time for all our leaders, right across the world, to come together and face the reality of climate change is upon us.  There is no time left to duck and weave.

Peter Sinclair of ClimateCrocks blogsite recently posted this video.  Watch it and ask yourself how much longer the leader of the most powerful nation in the world can sit on the sidelines of the greatest threat to our civilisation ever seen.

More animal lessons!

Continuing the fabulous photographs.

Did you see the first eleven from yesterday?  If not, go here.

oooOOOooo

oooOOOooo

Don’t they make one feel so wonderful!

Cities and forests; the outlook

Just a couple of items that came through my ‘in-box’ in recent times.

From the Payson Roundup newspaper of the 9th October, last.

Southwest forests are already in the early stages of a mega drought brought on by climate change.

Southwest forests are already in the early stages of a mega drought brought on by climate change that will result in massive tree die-offs and sweeping changes in Rim Country forests, according to an analysis published in the scientific journal Climate Change.

Severe drought will dominate much of this century, creating stresses on forests not seen for more than 1,000 years, according to the research that used tree ring samples from 13,000 trees, historical rainfall records and computer projections of future climate change.

The shifts will likely dramatically shrink the world’s largest ponderosa pine forest in northern Arizona, replacing pines with junipers at elevations like Payson and replacing junipers with chaparral and cactus at lower elevations.

The article concludes,

Unfortunately, the team’s climate prediction models suggest that within the next 40 years the region will fall deep into mega drought conditions. The models predict that even the wettest, coolest years in the late 21st century will exceed mega drought levels. In that case, the drought conditions of the past decade will prove the new normal rather than a bad stretch.

Williams noted that while winters in the past decade haven’t been exceptionally dry, summer temperatures have soared. As a result, the stress on the trees in the past 13 years has exceeded mega drought levels about 30 percent of the time — conditions not matched for the previous 1,000 years.

Now to a more positive message, this one from Climate Denial Crock of the Week for 10th October, 2012.

One of the clean little secrets about dealing with climate change, is that if we make our cities more efficient, and reduce their carbon footprint, we will also make them more resilient, quieter, more comfortable, more human scaled, more inviting,  and more fun.

Gnawing on a bone!

Dogs’ evolution shows why they ‘love’ gnawing on bones.

This is the second article on the BBC Nature website following yesterday’s item about why dogs enjoy a healthy breakfast.

oooOOOooo

Dogs’ evolution shows why they ‘love’ gnawing on bones

By Victoria Gill
Science reporter, BBC Nature, Ottawa, Canada

Social living drove dogs to evolve the “tools” for chewing bones, scientists say

Scientists say they have discovered why dogs love to eat meat and bones.

Ancient canines adopted pack-living about eight million years ago, to hunt larger prey, according to researchers.

The resulting evolution of their jaws gradually turned the ancestors of modern wolves, and ultimately our own pets, into “hypercarnivores”.

Dr Joao Munoz-Doran presented the findings at the First Joint Congress for Evolutionary Biology in Ottawa, Canada.

He and his colleagues from the National University of Colombia have created a canine “family tree”, piecing together the relationships between each of the more than 300 dog species.

“We compared species that have very different diets,” Dr Munoz-Doran explained to BBC Nature. “So we classified them as carnivores, hypercarnivores [animals that eat more than 70% meat] and omnivores [animals that eat meat and vegetation].”

The ancestors of modern wolves belong to this hypercarnivorous group.

The team’s analysis showed that the skull features that now distinguish a wolf – strong jaw muscles and enlarged canine teeth – first started to develop when their ancestors first began hunting in groups.

“We found a common evolutionary history for these traits,” Dr Munoz-Doran explained. “Eight million years ago was when [less forested, more] open habitats were spreading through Asia, Europe and North America. And when there are open habitats, the big prey group together. So there will be more eyes watching for a predator.”

The only way that dogs roaming the open plains could snatch very large prey from a herd was to work together.

“And after many generations of this grouping behaviour, there are new selective pressures on their [skull shape],” said the researcher.

This pressure meant that animals with larger teeth and stronger jaws were more likely to succeed in hunting, and to survive to pass on their large-toothed, strong-jawed genes to the next generation.

Animals with stronger jaws and larger canine teeth would have been more successful hunters

“They developed strength in their muscles – especially the muscles that close their mouth,” said Dr Munoz-Doran. “And bones that are more resistant to bending, so they could support the mechanical strains of biting the prey. “Over time, they became adapted to be ‘hypercarnivorous’.”

The researcher pointed out that domestic dogs had “very good evolutionary reasons to enjoy chewing a bone”.

“They have the tools to do that,” he told BBC Nature, “and they want to use their tools.”

oooOOOooo

Finally, to the side of that BBC Nature webpage were a few canine facts, as follows:

  • Common canines: Foxes, wolves, jackals, coyotes and dingoes are all members of this well-known group
  • Familiar faces: Wild canids are found on every continent except Antarctica
  • Communication is key: Previous studies of dog evolution have revealed that calls were essential for forming social groups and hunting larger prey
  • Pets’ past: All domestic dogs are descendants of the grey wolf

And don’t close without going here and listening to Steve Backshall howling with a wolf pack – (it’s a video as well – unmissable).
