What is the difference? We always had German Shephards growing up. If that is not a wolf, I don't know what is.

Sometimes you can get two different things to breed. It could be they got wolves and dogs to breed somehow. They can breed horses and donkeys, but you end up with a stubborn old mule.

If your able to cross breed like that, you end up with something weaker, not stronger.  

JohnR7: I was talking to a friend of mine yesterday that has a Phd in Animal physiology. All animals, including man have basicly the same physiology, a stomach, lungs and so forth.

DNAunion: A PhD?

Sponges are in the kingdom Animalia: they don't have lungs, stomachs, hearts, brains, nervous systems, etc. Seastars (starfish) don't have brains, or hearts, or blood. Flatworms don't have eyes - they have ocelli (simple light-sensitive "eyespots"), and their nervous system if far simpler than ours - they don't have a brain, just ganglia. A grasshopper doesn't have a heart - it has part of a tube that contracts and squeezes out blood Many animals have open circulatory systems, meaning that blood does not flow through blood vessels during its complete circuit (it "spills" out of the blood vessels and pools in blood sinuses, where it is later "picked up from"). Many animals are so small that they don't need lungs - gases pass directly through their "skin". Worms don't have bones. Lobsters have an exoskeleton and it is composed mostly of chitin - we have an endoskeleton that is composed mostly of calcium salts.

Besides, talking about whether certain animals have a stomach and lungs is talking about their anatomy, not their physiology. You've mixed oranges in with your apples.

Whatever, he has his Phd in Animal physiology and he does research on premature lung development in newborns. He uses animals in his research work.

Also, he teaches about the lungs in a medical collage here. It would seem sort of strange that a medical collage would hire someone with a degree in Animal Physiology to teach about the human respitory system if they were not very much alike.

Why can't you admit your mistakes.I thought personal price was frowned upon

Why are you always judging others, why don't you judge your own heart.

Matthew 23:24-26  Blind guides, who strain out a gnat and swallow a camel! [25] Woe to you, scribes and Pharisees, hypocrites! For you cleanse the outside of the cup and dish, but inside they are full of extortion and self-indulgence. [26] Blind Pharisee, first cleanse the inside of the cup and dish, that the outside of them may be clean also.


 

Please don't expect me to put store by that. I'll ignore it the same you ignore scientific facts

DNAunion: Apparently not grasshoppers, flatworms, sponges, lobsters, seastars, etc. He apparently doesn't even know these animals exist!

Of course, it is possible that what the PhD said was correct, but that by the time it made it to this board it got messed up. Perhaps you would ask the PhD dude to write something up himself and give it to you - you could then simply copy and paste it here, instead of trying to remember exactly what he said.
