Re: Salt water at 0 degrees F
Not sure if this is relevant but what the hey...
quote:
At depths greater than a few hundred meters, the sun has little effect on water temperature, because the sun's energy has been absorbed by water at the surface. In the great depths of the ocean the water temperature is very cold. In fact, 75% of the water in the world ocean (the great depths) has a temperature between 0 C and 2 C.
source
Sperm Whales often dive as deep as 1000 meters and have been recorded to dive to over 3000 meters.
Now that's not 0 F but still pretty cold.

Re: Salt water at 0 degrees F
The thing is Aaron wants to play games with temperatures. Either that or he is blindly reciting something he read or heard or even possibly he doesn't know what he is talking about so doesn't realize how bone headed he sounded.
It is obvious that the info about the tuna he presented was in F and that the info about the whales was in C. The scary thing is he was unable to tell that his sources were using different temperature scales. But then again I tend to expect this from Creos.

Re: Whale legs
Your patience, thoroughness and savvy are commendable. Thank you for making this an interesting debate.
Aaron writes:
Truth is that certain regions in an embryo's body send signals to induce the formation of other parts. I suggested that what are considered limb buds could be temporary signaling lumps.
Now, let me ask you how this makes them different from what are considered limb buds in other tetrapods? Don't they perform these same functions in tetrapods? Don't they also appear at comparable stages in development, and grow in the same bodily locations, in both cetaceans and tetrapods?
They still seem to be homologous structures, albeit homologous structures from which some components have been lost.

Aaron writes:
But, I was specifically referring to the SonicHedgehog protein and Hand2 protein, which are involved in limb and digit development respectively. Neither of these were found in the limb bud.
Ah, I see your point.
However, given that the lack of these proteins is probably the actual reason why whales have no hind limbs, I don't think it's such a big deal that whale limb buds don't have them.

I think Aaron was just a bit careless with the scales. We've had the metric system in Canada for more than thirty years and people of my generation still use Fahrenheit and Celsius in the same sentence. I assumed he meant 0 Celsius.

Re: Salt water at 0 degrees F
Lets look at his original assertion
Message 96
Tuna can swim in water down to 43 degrees, but whales can swim in much colder water - as cold as 0 degrees. Warm blood enables whales to inhabit extreme ecological zones - unlike fish of comparable structure.
If he was using celsius the tuna would be in very hot water. That is warmer than a hot tub.
Lets see what Aaron's explanation is for this. He needs to learn that fundie sites lie or are just plain wrong.

Facts don't lie or have an agenda. Facts are just facts

Re: Salt water at 0 degrees F
The corrected statement would be something like "Tuna can swim in water down to 6 degrees C, but whales can swim in much colder water - as cold as 0 degrees."
That isn't nearly so impressive as comparing 43 to zero.

Hi, Aaron.
Aaron writes:

I agree with you: the term "vestigial" implies evolution. It doesn't technically have to, but there's really little point in arguing otherwise.

Aaron writes:
Gills tend to leak a lot of body heat. So, if God purposed to have whales inhabit cold climates - gills would have been a disadvantage - since they would have to be very large gill openings to support the oxygen needs of such a large animal.
There are still some problems with this reasoning.
First, body heat isn't really that important. Most animals in the Arctic and Antarctic spend their entire lives with their body temperature equal to the temperature of the cold water around them. Hypothermia is only really a serious problem when it causes the formation of ice crystals.
Second, body size isn't really that important, either. A school of herring can substitute just fine for a whale, and, due to a higher reproductive rate, they turnover biomass much faster, meaning that, overall, they can probably be fed on and sustain more predators and scavengers than whales.

Re: Whale legs
"And, "a few similar ear bones" is understating it. Don't you find it curious that the only time a whale-like ear bone has ever been found in a terrestrial mammal, it fits nicely (chronologically and geographically) into a series of fossils bridging the gap between hoofed mammals and whales?"
Although, packicetus is considered to be semi-aquatic - so it isn't so odd to find a bone structure that allows them to hear better underwater.
It's not like we're talking about a bone that is non-existent in terrestrial mammals -the involucrum of packicetus and whales is thicker than it is in terrestrial mammals, but they all have the same type of bones.
It is true that a number of extinct semi-aquatic mammals have an ear structure that helps them hear better underwater. The fact that they have biology that matches their environment in no way undermines a creationist viewpoint.
What's interesting is how much evolutionists harp on the similarities of certain features to connect the dots to common ancestors, but don't have an issue with the dissimilarities.
Would it make a difference if I pointed out all the differences in packicetus ear structure compared to modern whales?
Pakicetus lacked two important adaptations which are present in modern whales. In living whales, the ears contain large sinuses that can be filled with blood, allowing the animal to maintain pressure while diving. Modern whales also transmit sound vibrations to the inner ear using a "fat pad," which allows them to hear directionally underwater.
(Whale Transition)
In addition, while whales have a reduced semicircular canal, pakicetus' were closest in canal arc size to modern artiodactyls.
Its also interesting that toothed and baleen whales have difference in ear anatomy. Baleen whales have middle and inner ear bone casings that are directly fused to the skull while toothed whales do not. The fused setup of baleen whales is more similar to manatees. By appearance, manatees would seem to be closer related to whales than packicetus - but they are not considered closely related. You can find anatomical similarities in distantly related species.
"You realize that this is just a description of the shapes of the bones, right?
What "analysis" do you think has happened here?"
What other types of bone analysis is there? All I've heard is how closely the pelvis of whales matches the pelvis of land mammals - and here is somebody talking about the detailed differences.
Again, it's like the differences are no big deal. All that matters are the similarities. Yet, obtaining major structural changes through random mutation is no small matter.

Re: Variation and Perfection
Granny M
"I think you comparing it to the wrong mammal pelvises. Here is indohyus, one of the oldest fossils in the whale lineage;
Note the small, simple pelvis. It is similar to those of modern whales."
What does "simple" pelvis mean. It looks pretty much the same as a dog pelvis.
So, whale evolution went from the small pelvis of the Indohyus to the much larger pelvis of Ambulocetus and back down to the smaller pelvis of modern whales.
One main difference between the pelvis of whales and other land mammals is that the two side in whales aren't connected.
"Huh? You showed one that was 5mm long. That right whale's is about 18cm long. Look at the picture."
I mispoke - the original picture I showed was also measured in cm. Apparently I'm having some issues relaying proper measurements.
"No. There is more variation between individuals of the same sex than between the sexes in general. Look at these two pictures of fin whale pelvises;"
There are also several species of Balaenoptera physalus which inhabit various corners of the globe. Its not unreasonable that the geographically separated sub-species might develop slight differences in bone size.
"Not because he, as a professional anatomist, knows a pelvis when he sees one? Okay.
It should be noted though that you were willing to take Mead's word for it when his ideas suited you,"
The differences are greater than the similarities. Call it a pelvis. Call it whatever you want. Its a man-made term to describe similar bones. In this case, the bones are not really similar - they look very little like the pelvises of quadrupeds - it has more to do with the region in which they are found.
Fish also have a pelvis - named so because of the general shape and general region of the bone.
"You cannot claim that the whale pelvises are perfect and that they also vary. The two claims are logically incompatible.
Besides, not all whales even have these bones. Some lack much of the leg structures, with tiny pelvises, no femurs at all, no tibias, etc. How vital a function can these bones serve if they are not always found? "
I understand the point you are trying to make, but I think it undermines the idea of what constitutes good design. Wheels are the "perfect" design for moving cars along. Yet, they are found in many different sizes. Windshields are a "perfect" design for keeping bugs out of our mouths when we drive, yet they vary from car to car.
It is perfectly reasonable for a designer to tailor fit a "perfect" design for the size, shape, and reproductive styles of different whale species. It would be unintelligent to fit killer whales and sperm whales with the same size pelvis bone. I'm sure natural selection has played a roll in creating variations in whale pelvises as well.
"Why would God, creating from scratch, need to fuse two bones together? Could he not make a single, whole bone in the same shape? If the shape is so vital (and I have demonstrated above that this is false), why not do it with a single original bone? Why fuse together two bones that can be recognised as being part of land-mammal ancestry?
How would you tell the difference between a group of fused bones and one single bone that looks exactly the same? It doesn't look like whale bones have jagged lines to indicate that the different parts were formed separately and later fused, as is the case in the human skull. Most of the whale pelvises that don't have smaller nobs do look like one smooth piece - and even on these, one of the ends are labeled a femur.
"Do you believe that there are limits placed upon God (beyond the limit that prevents him from doing the logically impossible?)"
God can limit himself. He's not like an exploding bomb whose power must be emitted without control. The question becomes a theological one - why would God do things the way he did them.

Thanks for getting my back.
It was a careless oversight on my part. Obviously whales can't swim in ice.
Contrary to my accusers opinion, I wasn't quoting from a "fundie" site - so the mistake is mine alone. I do my own research and don't quote from creation sites because I know they wouldn't hold any credence with you.
My point was that whales have some advantages over tuna when it comes to extreme environments. Besides, temperature ranges were not the only information I was using to suggest whales occupy a unique ecological niche.

Modern whales also transmit sound vibrations to the inner ear using a "fat pad," which allows them to hear directionally underwater.
Right. The similarities are arbitrary, suggesting common descent or wild coincidence; the differences are adaptive, suggesting adaptation.
What other types of bone analysis is there? All I've heard is how closely the pelvis of whales matches the pelvis of land mammals - and here is somebody talking about the detailed differences.
Again, it's like the differences are no big deal. All that matters are the similarities. Yet, obtaining major structural changes through random mutation is no small matter.
Again the differences are explicable as adaptive. Clearly whales don't need legs that they can walk on, and natural selection would have dispensed with them just as a creator would have done.
But the similarities are baffling except as a result of common ancestry. Here's an anatomist describing a dissection of a right whale:
Nothing can be imagined more useless to the animal than rudiments of hind legs entirely buried beneath the skin of a whale, so that one is inclined to suspect that these structures must admit of some other interpretation. Yet, approaching the inquiry with the most skeptical determination, one cannot help being convinced, as the dissection goes on, that these rudiments really are femur and tibia. The synovial capsule representing the knee-joint was too evident to be overlooked. An acetabular cartilage, synovial cavity, and head of femur, together represent the hip-joint. Attached to this femur is an apparatus of constant and strong ligaments, permitting and restraining movements in certain directions; and muscles are present, some passing to the femur from distant parts, some proceeding immediately from the pelvic bone to the femur, by which movements of the thigh-bone are performed; and these ligaments and muscles present abundant instances of exact and interesting adaptation. But the movements of the femur are extremely limited, and in two of these whales the hip-joint as firmly anchylosed, in one of them on one side, in the other on both sides, without trace of disease, showing that these movements may be dispensed with. The function point of view fails to account for the presence of a femur in addition to processes from the pelvic bone. Altogether, these hind legs in this whale present for contemplation a most interesting instance of those significant parts in an animal -- rudimentary structures.
Now if we take that with all the parallel cases in other animals, the whole "God just felt like doing it that way for some unknown reason" hypothesis looks distinctly flakey.

Hi, Aaron.

We expect differences, because the Theory of Evolution is fundamentally about the differences between species. The similarities, however, are key to understanding what these differences mean.
If two species are only similar in ways that are functionally significant, then we can chalk up the similarities to common design or common adaptation. We don't really have much to say on the differences at this point, but we could easily speculate that they, too, have something to do with function.
But, if two species are similar in ways that are functionally superfluous, or even functionally inferior to other available options, then we need to look to something other than function to explain why they are the way they are.
Combining common descent with evolution leads us to an explanatory framework that beautifully accounts for both the similarities and the differences.
Intelligent design, however, leaves us with a bafflingly quirky designer and the assumption that we'll soon realize that things we currently think are inferior are actually the best fit for the role they are intended to play (which we'll also discover in the future).
I'm not saying that it's entirely impossible that we'll get to that point, but don't you agree that it sounds absurdly sketchy?

Re: Salt water at 0 degrees F
But as has been pointed out, you attempted make it seem like there was a huge disparity.
The difference between 43 f and 0f is quite a bit.
But not nearly as much of a difference between 6 c and 0 c.
Of i you want it if F 43 and 32.
Doesn't seem to be nearly as impressive does it.
