I forgive myself in part because I did not visit the original link which provided you with the statistics based on humans.<br /><br />One thing I would like to add: lard.<br /><br />Blubber. Adipose. Natural heat insulation.<br /><br />@John: thanks again for an unexpected interesting topic!Richhttps://www.blogger.com/profile/09091246964133101706noreply@blogger.comtag:blogger.com,1999:blog-10760709.post-44917871372539317822010-01-06T14:06:28.964-05:002010-01-06T14:06:28.964-05:00The assumptions made in the original post are way,...<i>The assumptions made in the original post are way, way off.

He might have been able to make it back to his truck, but he wouldn't be able to drag the carcass with him. And he wouldn't be able to find it again if he left it where it had fallen. If he didn't want the wolves to eat his deer, he would have to stay with it all night.<br /><br />It was sub-freezing temps, but he was worried about the residual body heat causing the meat to spoil. So he gutted the animal, and propped the body cavity open with sticks to make sure that it would cool down.<br /><br />Animal fur is an amazing insulator, and animals evolved to thrive in arctic conditions have even better insulation. What did the Inuit use to keep from freezing to death, anyway?<br /><br />Click back to the original link at Wolfgnards. They have some data to back up their calculations as to how fast a "carcass" cools down, but look at what they are using to prove their point and you see that they are talking about how fast a <i>human</i> body loses heat after death.<br /><br />Hey! I thought humans were basically fur free! Isn't that why we put on coats when going outside when the snow falls? Isn't that why the Inuit fashioned garments from seal skin, fur side out? I was always under the impression that it was because human bodies have a high thermal conductivity, and the insulation shifts it lower.<br /><br />Also, wasn't that Tauntaun in the movie considerably larger than a human? Isn't that why humans rode them in the first place?<br /><br />The rate of heat loss isn't just due to heat insulation, but also a function of surface-to-mass ratio. Generally speaking, larger animals have a lower StM ratio than smaller creatures, and usually have a problem keeping cool.<br /><br />My shih tzu is a lapdog, and his body is draped with the most amazingly long and luxurious coat of fur you would ever hope to see. But he still starts shivering before my short-haired pit bull feels the cold, because he has less tissue between his skin and his vital organs. <br /><br />A well insulated lapdog's core body temperature drops faster than a barely insulated dog that is five times his size, because he has less mass to store thermal energy.<br /><br />The assumptions made in the original post are way, way off. What Earthly animal would be closest to a Tauntaun's thermal conductivity and mass? What creature found close to home would have fur that had insulating properties close to that of an animal that was evolved to survive on ice planet Hoth?<br /><br />Howsabout a grizzly bear!<br /><br />So wake me up when the geeks at Wolfgnards find the stones to go and conduct some tests on grizzlies they kill during an arctic snowstorm.James R.
