It’s an ill wind …

It’s an ill wind that blows nobody any good!

Amazing to find that the saying was recorded as  far back as 1546 when it is first recorded in John Heywood’s A dialogue conteinyng the nomber in effect of all the prouerbes in the Englishe tongue: “An yll wynde that blowth no man to good, men say.”

The reason this comes to mind is that good friend, John H. from here in Payson, recently sent me a piece under the title of Spider’s Web.  This is how it started,

An unexpected side-effect of the flooding in parts of Pakistan has been
that millions of spiders climbed up into the trees to escape the rising flood
waters.

A quick web search came across the item in National Geographic online, from which I republish this:

Cocooned Trees, Pakistan

An unexpected side effect of the 2010 flooding in parts of Sindh, Pakistan, was that millions of spiders climbed up into the trees to escape the rising flood waters; because of the scale of the flooding and the fact that the water took so long to recede, many trees became cocooned in spiderwebs. People in the area had never seen this phenomenon before, but they also reported that there were fewer mosquitoes than they would have expected, given the amount of standing water that was left. Not being bitten by mosquitoes was one small blessing for people that had lost everything in the floods.

John’s email also included more images, that are reproduced below.

So it looks as though we have much to learn from spiders as well as from dogs!

Or maybe, it’s just another example of the beauty, magic and mystery of nature!

Reading Planet Earth, part Four

The final episode from the series of four 1-hour videos from National Geographic.

The first episode plus the introduction can be seen here, the second episode can be seen here while the third can be seen here.

I wasn’t quite sure what to expect from this last episode.  The third episode had shown how good science could determine the deadly cause and effect of past times and enact critically important solutions.  Well, the final episode had the same underlying theme.  That despite the huge scale of change and transformation required by millions of people to restore the planet to health, it’s not impossible, not by a long chalk.

So I will close these past four Posts by thanking Dogs of Doubt for first bringing these videos to light.  I truly hope that they have been for you as  Perfect Stranger described them in his Post, “they explained so much that it is impossible not to recognize the changes we have made to our environment.”  Nothing to add to that.

More learning from dogs!

A peek at a very interesting article in the February issue of National Geographic magazine.

Big thanks to Bob T. here in Payson for sending me a recent email that contained the one line, “There is a lengthy article entitled “Mix, Match, Morph” in the February issue of National Geographic.  I strongly suspect you will find it of interest.”   Understatement big time!  The article is wonderful.   It is also available online! 🙂

The premise behind the article is, as the opening words reveal,

How to Build a Dog

Scientists have found the secret recipe behind the spectacular

variety of dog shapes and sizes, and it could help unravel the

complexity of human genetic disease.

As is made clear early on in Evan Ratcliff’s text, the huge variety in the breeds of dogs is a very recent occurence,

For reasons both practical and whimsical, man’s best friend has been artificially evolved into the most diverse animal on the planet—a staggering achievement, given that most of the 350 to 400 dog breeds in existence have been around for only a couple hundred years.

And later Ratcliff writes,

The breeders gave no thought, of course, to the fact that while coaxing such weird new dogs into existence, they were also tinkering with the genes that determine canine anatomy in the first place­. Scientists since have assumed that underneath the morphological diversity of dogs lay an equivalent amount of genetic diversity. A recent explosion in canine genomic research, however, has led to a surprising, and opposite, conclusion: The vast mosaic of dog shapes, colors, and sizes is decided largely by changes in a mere handful of gene regions.

What is critically being discovered is,

Already, more than a hundred dog diseases have been mapped to mutations in particular genes, many of them with human counterparts. Those diseases may have a whole array of mutations leading to a risk of disease in dogs, as they do in us.

It would be wrong, without permission to reproduce the article, to include more but you can quickly go here and read it yourself.  Except I can’t resist closing with the last sentence from the article,

After all, he points out, there are millions of dog lovers out there willing and eager to help with the fieldwork.

Ain’t that the truth!

And don’t miss the fabulous photographs of dogs taken by Robert Clark which you can see here, another example of which is below.  Robert Clark’s website is here.
