Sorry this took me so long. Busy day before Christmas.
Not to worry. My laptop crapped itself & my net time has been severely limited, hence the late reply.
Im not going to cover every little bit of detail because its lengthy & I got a lot of Zero punctuations to catch up on.
Iv probably written more than you care to read. But still, I hope you had a good Christmas.
I was wondering about you disappearing all of a sudden.
Christmas is always good, hope yours was too.
And don't worry, I don't mind walls of text at all in a good discussion. I just hope me writing even more back is what you expected. Otherwise... surprise!
Ok. The article you posted covered a lot of detail about Chromosome 2 but still didn't seem sure of itself, as can be expected. It also didn't mention anything about a fusion inverting the sense/anti-sense strands from the joing of the ends of each arm.
Well, I can't really go more into it detail on chromosome 2, I'm not that versed with genetics yet.
As for your examples. From a creationist perspective it makes sense to have all organisms compatible with the same nutrients, even if in some cases minor adjustments are needed. Linoleic acid doesn't need to be synthesised since its aquired from diet. DNA is read in one direction due to the geometrical structure of the molecule. Id say its more of a compromise in having two strands synthesised simultaneously rather than seperately. I suppose an advantage to this would be to avoid any hairpin loops forming from a supercoiling single strand. Erector Pili muscles contract for insulation, possibly as a result of the blood flow being shunted away from the surface. And the giraffes inferior laryngeal nerve can yield several explanations other than an evolutionary one; it could be a minor deformity or a consequense of foetal development. Or it might have a purpose. All mammals have an extended inferior laryngeal nerve which could mean that perhaps its intended to have a delayed signal, possibly a feedback mechanism of sorts. If there is a purpose in this than we're never going to discover it by just writing it off a 'evolution did it' & then ignoring it. The field of genetics has been delayed for about 30 years because non-protein coding DNA was written off as evolutionary junk. And countless people have died or become sick because glands & organs that were deemed vestigial by evolutionary thinking were either removed or zapped with x-rays with roentgenium.
Alright, I suppose a standardized enantiomer could make sense, I give you that.
Linoleic acid and other EFAs are taken up through food, yes. But there can be deficiencies and if they are essential for synthesizing components that affect cellular, neurological and inflammatory functions and for cell signalling and DNA transcription one would assume that any all-knowing creator building the chosen species would just put the means to make it ourselves right into the metabolism. It's not even hard to do, a lot of non-mammalian animals don't have issues with it.
The fact that DNA can only be read from 5' to 3' is because our transcriptase only works this way so one strand is read in a simple linear sequence while the other one simultaneously has to transcribe a few codons at a time in reverse direction. However, I don't see why this way should be preferable over simply having something that can transcribe in both directions. Or a second transcriptase for the 3'5' strand.
Similarly, during translation there are two release factors, RF1 and RF 2. RF1 only detects stop-codons UAA and UAG while RF2 is on the look-out for UAA. Now, first there's three stop-codons that also need two different RFs to act with. Is that the most logical solution you could think of?
Arrector Pili muscles insulate diddly squat, if you pardon my Flanders. I haven't been able to find concrete studies on efficiency rates but that's probably because they're laughably small. A normal human being doesn't have the hair density needed to have any proper insulation from trapped air nor an advantage of scaring off predators with it, yet those are the uses of it throughout the mammalian world and coldness & fear are the two situations where goosebumps are the most common occurences. Now, an evolutionary route from hairy primate ancestory such as Australopitheci that would infact have had use for a pilomotor reflex for both warmth and intimidation gives a pretty logical story of origin while Creationism is pretty much left to come up with any explanation besides "because God".
Sure, we've found a use for things like the vestigial cecum that is now the appendix but at least that's a proper organ, a little muscle sitting on a hair's base doesn't exactly provide the most versatile of functions.
The recurrent laryngeal nerve in fish is the most direct route from brain to the gills, during the evolutionary lengthening of the neck and lowering of the heart the laryngeal nerve was now trapped under the aorta ascendens and had to lengthen (because lengthening of a nerve is easier than lengthening the biggest bloodvessel) since it couldn't just pass through the aorta. Might there have been some kind of mutation at one point that through sheer luck would have had the nerve free from the loop? Possible, but since there is no direct advantage to it there was no specific selection for it and it vanished again.
All mammals have this setting, yes. Evolution has a flawless explanation for that occurence as I've just explained. If it was a "minor deformity" it wouldn't be present in the exact same setting or in logical varieties of forms throughout the animal kingdom. Foetal development is no excuse for a design flaw if talking about an all-powerful, all-knowing, perfect being that could eliminate a flaw like that with ease.
I don't see what signals the laryngeal nerve should even delay, I'd prefer it if my cough reflex happened as efficient as possible, same for voice control or breathing. Besides, depending on what delay time you want you could use different kinds of nerve cells, make them thicker or more insulated, put more behind each other as a delay or just spring for hormones if you've got the time. Signal delaying through a ridiculous axon length that runs through a rather vulnerable part of the body twice and if damaged in any time that isn't the last decades basically kills you through loss of voice and an unprotected airway is, at best, a very odd design choice.
"Evolution did it" and research into it aren't mutually exclusive. Appendices were cut because there was no known use for it and eliminating a possible inflammation centre is more important than something without a use, but why do you think did we discover that it had a part in the immune system? Not because we ignored it since discovery. Besides, standards in medicine change all the time depending on latest findings but they take time to apply. I think for more than a decade now atropine has been used by pretty much every physician at a CPR for ventricular fibrillation, a few years ago long-term studies suggested that it really had no use either way and has slowly been faded out, yet I still know one or two doctors who use it. You go with what worked best so far, it takes time to perform studies and it takes even more time to convince everyone to change. I don't see how that is anyone's fault.
You see, God is mysterious but theres no sin in discovering those mysteries. And I dont believe that the supernatural should be excluded from science but I do however believe the supernatural should itself be thouroughly investigated. Many will disagree with this last statement but I believe its better to experiment & examine something, even if it seems rediculous, rather than dismiss with skepticism. But as far as science goes I believe we should be investigating what already exists then apply theories on its origins afterwards. Thats the only thing I had agains a lot of creation sources, they were aimed more at believers who were seeking answers rather than made public friendly. And I know exactly what you mean by citing its own articles. It is perfectly acceptable in literature to cite secondary sources but I believe that if they want to prove a point they should site the original article. Again, hopefully that will change in future.
I don't disagree with investigating the supernatural, what I meant was using supernatural explanations such as "god made it this way just because he wanted to" or "magicians control the tide" as sufficient explanation to rely your hypothesis on, which is exactly what Creationism does. Or, to stay closer to actual claims, "fossils are temptations planted by the devil".
Continuing there, you arbitrarily pick one religion and the explanations that come with it, then set out to find something that supports these explanations. And it doesn't even matter that time and time again your biblical sources have been shown to be wrong about the simplest things (rabbits don't chew their cud, insects have six legs not four, bats aren't birds but mammals, hell even the trumpets of Jericho are silly since Jericho never had any walls) Creationists still pretend like the book is infallible. If the bible is the "eternal word of god" (because it itself says so) then surely the fact that not even the omniscient creator knows his simplest stuff has to be alarming. Science changes theories based on new evidence, the bible on the other hand is, based on its own premise, eternally wrong about stuff.
And if it's wrong about simple facts of nature, why could it not also be completely wrong about other things?
And as I have stated before (because I'm honestly curious if there is any argument FOR it), how is it
any more likely that everything was created as-is in seven days than that it originates from the goddess of chaos, Eurynome, dancing on the waves of the endless surrounding ocean to separate land from sea and fill it with creatures like nymphs and titans?
EDIT: A second thought I might be able to slip in here: if day 3 saw creation of plants and day 6 creation of animals... what's up with mushrooms?
