Because I believe they were created.

You miss the point. Why should we go and study on the possible evolutionary lines of these particular animals for you. Why don't you go do it, then come back and explain why it doesn't work in your opinion. I get tired of people choosing a specific animal and just saying "how did THIS ONE evolve". It's not our problem. The information is out there. Find it, learn it then come and make an argument.

Please tell me how a dolphin's sonar evolved.

*sigh*. i suppose i'll give this one a shot. first off, even humans have a primitive sonar-like ability. if you are standing with a brick wall in front of you, you can shout and hear the echo, which gives you a good sense of how far away the wall is. in fact, they have even shown in studies that humans are good at judging distance this way. now, underwater, sound carries better than in the air, so just being underwater would improve that skill. so all dolphins would really need to do is refine this already present skill for greater accuracy. doesn't seem like it would be too hard for that to happen.

Don't know and don't feel like scouring the internet for an explanation.

They say the giraffe neck evolved, not piecemeal, but simultaneously? Very unlikely. As to the bombardier beetle, they made a mistake. What they didn't realize, and I didn't until I looked at Incredible Creatures that Defy Evolution, was that, instead of shooting off a single puff of chemicals, they shoot the chemicals in a stream. Here's the absurdity of the Evolution of the bombardier beetle.

A beetle gets a chemical. Now, since it only has one chemical, it has to use this chemical to get a bunch of other chemicals. Now, once he does this, he realizes he forgot something... the inhibitor. Now it's too late. However, even if he did have the inhibitor, he can't use the mixture. Now he has to use the same chemicals to develop an antiinhibitor. Now if a preditor attacks him, he can foil their attack... by blowing himself to smitherines. Oh, yes. He forgot the tubes. So now he waits millions of years until he evolves the tubes he needs to actually use the chemicals. He also can turn the tubes. Coincidence and chance? Doubtful.

Possibly, but it's one thing for you to detect a non-moving object a few feet away, but it's another to detect a moving object several hundred feet away.

as i explained, improved sonar would be selected for, allowing for greater distance and accuracy. this would occur by modification of their already existing sonar abilities, limited as they would initially have been.

That's not a bad idea actually.

Novaknight, do you beleive that Noah took two bombadier beetles onto the Ark or did he just take two of the beetle "kind"?

Neither. Beetles don't breathe through their nostrils. Bugs breathe through their skin. They could have all dug into the dirt to escape the Flood, which was global.

ANd here we see why we shouldn't go and do your studying for you. Very unlikely, is it? Compared to what, exactly? And how unlikely is it, exactly? Give us the data, please.

Oh, so originally they could only detect fish a few inches away.
