Cadaver Dogs: the Nose Knows

[ready to go]

I am a little bit of a fan of true crime stories, and often dogs are used to find the remains of a homicide victim.

Cadaver dogs are trained to locate and follow the scent of decomposing human flesh.

Dogs' sense of smell is far more acute than that of humans – the nose of a German shepherd contains about 200 million olfactory cells, while a human nose has about 20 million.

In a recent study, the forensic pathologist Lars Oesterhelweg, then at the University of Bern in Switzerland, and colleagues tested the ability of three Hamburg State Police cadaver dogs to pick out – of a line-up of six new carpet squares – the one that had been exposed for no more than 10 minutes to a recently deceased person. Several squares had been placed beneath a clothed corpse within three hours of death, when some organs and many cells of the human body are still functioning. Over the next month, the dogs did hundreds of trials in which they signalled the contaminated square with 98 per cent accuracy, falling to 94 per cent when the square had been in contact with the corpse for only two minutes. The research concluded that cadaver dogs were an "outstanding tool" for crime-scene investigation.

In one study involving four dogs and their handlers, anthropologist Keith Jacobi of the University of Alabama says cadaver dogs were able to detect remains at all stages of decomposition. Performance varied between dogs, but some could locate skeletonised remains buried in an area of 300ft by 150ft. "The few single human vertebrae I used in the study were well over 25 years old, and dry bone," Jacobi says. "This made the discovery of one of these vertebrae, which we buried in dense woods 2ft deep, by a cadaver dog pretty remarkable."

Nobody really knows how they do it.

Mark Harrison, national search adviser for the UK National Policing Improvement Agency in Wyboston, Bedfordshire says: "If you ask me, 'Will a machine replace dogs?' I would say no."

This miracle of technology, beyond what any humans can devise or even understand, is an amazing testament to God's creation.

Hitler also had more compassion for dogs then for people.

And that makes sense in what way?

evolution is indeed remarkable. and i happen to know for a fact these dogs are atheists.

Using that logic, if you took an iPod and gave it to the tribes in the Amazon that have no contact with modern humans, they would see it as proof of their god.

You praise dogs while advocating genocide, misogyny,racism and homophobia.

"evolution is indeed remarkable"

And mythical, just like the Flying Spagetti Monster, as I demonstrate.

"and i happen to know for a fact these dogs are atheists"

No, they have no religion, just like a bald man has no hair. Atheism is a religion, as I demonstrate.

"they would see it as proof of their god"

They would certainly see it as demonstrating intelligent design and they would be right.

"You praise dogs"

I love dogs! But actually this post is about praising the dog's Creator.

"while advocating genocide"

When commanded by God, which hasn't applied in practice since Biblical times, as I explain.

"misogyny"

Male dominance is not part of being Jewish, it's part of being a mammal. Atheists are accused of sexism too.

"You may drive out Nature with a pitchfork, yet she still will hurry back."

Judaism recognizes this and manages it in a very humane, reasonable way, as I explain.

"racism"

There is no modern concept of "race" in the Talmud. We are all children of Adam. Darwin was one major founder of modern scientific racism, believing that it was only a short matter of time before the "higher races" would exterminate the "lower races", as I point out.

"homophobia"

I don't have an irrational fear of homosexuals; they don't really frighten me at all. I do very rationally condemn sodomy, as I explain.

No - they would see something they can't understand because of their lack of technological sophistication and therefore attribute it to their god. Pretty much the same as you do.

Finally, a normal, reasoned post that advocates contemplation of nature and it's connection to God.
More of this, please; less of misogyny, homophobia, and genocide.

Thanks.

Since the modern manufacturing process is unknown to them, primitive peoples will believe that the manufactured goods of the non-native culture have been created by spiritual means.

http://en.wikipedia.org/wiki/Cargo_cult#Causes.2C_beliefs_and_practices

There is however an intelligent designer involved, whether some god or ancestor spirit.

They would never suggest that manufactured goods were created spontaneously by random chance, as atheists believe regarding the dog's nose. Obviously, that's absurd as I explain here.

It would be like asking Rush Limbaugh to stick to the weather report!

Here's a Limbaugh quote
"Feminism was established so as to allow unattractive women easier access to the mainstream of society."

This doggie's just gorgeous! She looks part lab part shepherd. We have one named Sunshine at the kennel just now. A beautiful girl and SO smart and eager to please. :^)

Human nose and sense of smell can be trained to be extremely accurate.

Ask any chemical engineer around.

I can smell easily how many chlorine atoms does a compound have and quite well tell the various functional groups a molecule has by just having a smell. Human nose is not as keen as that of the dog, but more suitable to analyzing and investigating things than that of dog.

I quit smoking while I was in college. To hone my nose.

The canine nose is a wonder of nature, but trained human nose is not to be belittled.

Gives an all-new definition for chutzpah.

I'm not saying I agree with that one. But sometimes I feel a little bit like the Rush of the Jewish blogosphere.
