Athiests don't usually ridicule Santa
Indeed. Of course the usual issue for any adult is whether the fact that Santa is fictional should be broken to children. And the same is true with atheists and believers in gods. But not here on ToL, the atheists are very happy to share that knowledge with the children, er I mean the deluded, maybe I should rephrase that, the believers in fiction. Hmmm.
The other thing is that while Santa is a fictional character, its mythology isn't anywhere as nasty as most god belief fiction.
aliens, multiverse, Startrek etc. Is it because they know those things aren't real, and there is no evidence. (Some atheists even believe in some of those things)
Yes I could name several atheists who are ardent believers in Star Trek. That seems to go with the territory for some of them. Unlike the god nonsense, there is a possibility that the multiverse is real. But as you say, there is no empirical evidence for it so it must remain a religion.
What Crow does is suggest a POSSIBLE mechanism to try make the data fit his beliefs. Crow suggests an unrealistic model of "quasi-truncation"... essentially splitting hairs with truncation, saying the truncation model is not realistic.
*You likely did not notice, but he admits we are genetically inferior to our stone age ancestors.
*You might have also missed that he says things such as...
"the overall impact of the mutation process must be deleterious"
or
" I do regard mutation accumulation as a problem"
Yes. But I think he is out of date. It is quite an old paper in a quickly developing area of investigation.
Crow was discussing humans, not embyos or zygotes.
He should have been discussing all three, because it is relevant I think. The embryonic process is a first testing ground for the viability of mutations.
But in any case you might not understand what the words 'extroplate' and 'data' mean. The fossils themselves are the data. They are not "non-existent". Extrapolation happens when you observe data and ruminate what happened over vast past time periods, or what might happen over future time periods.
I think you might be the one that does not understand 'extrapolation'. I recommend looking up how that word is used in science.
Stuu: And what precise difference (genetic sharing / mutation rate between bacteria and human) are you meaning to explain by that?
Several methods that are different such as horizontal Gene transfer and reproduction by binary fission.
And now for the explanation...?
That is a great example of the 'wild extrapations' we talked about. The data is humans have a range of morphological differences. Extrapolating it over millions of years is what has often lead to false conclusions, as it did with Neandertals.
You are still committing the logical fallacy of composition. You are asserting that because some adaptations take only a short period of time, that all adaptations take short periods of time. I gave you two very precise examples of hair colour changes versus skull morphological changes. I can cite the evidence for those timescales if you want. Otherwise you will need to be much more specific and less logically fallacious if you want to be credible on this point.
Speaking of their beaks, the growth seems controlled by a genetic switch.
https://news.harvard.edu/gazette/sto...t-their-beaks/ That almost seems like a design feature to help them survive changing environments.
Natural selection certainly produces the illusion of design. Although, as we have discussed, it often has the appearance of shoddy engineering.
Anyways... speciation can and does happen rapidly. Finches can be observed 'speciating'. I can give you links if you wish.
Well it is encouraging to see a creationist describing processes of evolution, but once again you need to say whether you are talking about finch beaks, which are a relatively trivial adaptation, or the whole bird-full of adaptations, which is more complicated and covers a longer timeframe.
HA HA... you should have read the article. It says "The evidence for an evolutionary change SURPRISED me,” said Stuart. “The pace at which the change was happening SURPRISED me even more"
Well, there you go. What is that doing in a peer-reviewed scientific paper?
Stuu: So why is there extinction then?
Mutations...selection....drift...lack of genetic variation...changing environments.
Well indeed, I couldn't agree more, especially with the lack of variation and changing environment bits.
But why are there extinctions according to your fantasy of Calvanist genetics? Shouldn't you add poor design to that list?
Yeah... "MAYBE" this and MAYBE that.
Alright then,
almost certainly natural selection has found an immune-related use for the tissue, and it may retain an aspect of bacterial storage, without being the same function as in ancestral species.
Evolutionism involves the non falsifiable belief organs can become vestigial.... useless or, diminished or take on new purpose, due to common ancestry...MAYBE.
It's not non-falsifiable. All you have to do to falsify the claim is to demonstrate that the organ actually retains the full function that has been claimed to have been partly or completely lost.
Evolutionists once used the useless appendix as a 'proof' of common anceatry. Science proved that belef was wrong...our appendix has function.
But it is still vestigial by definition.
My favourite example of vestigiality is the plantaris muscle which runs down the back of the lower leg. It is very important for tree-dwelling primates in the grasping of tree branches but has lost almost all of its function in humans.
But, the creationist might claim, it does have the same function right? Who does the befuddled evolutionist think he is to claim that it has no useful function? Well, about 10% of humans don't even have a plantaris muscle. So it is indeed vestigial and its absence is spreading in the population. It is clear evidence that our distant ancestors were tree-dwellers.
Not sure of the original design, since we now have several thousand years of mutations. But, you can easily find articles declaring our bacteria is not vestigial, but a safe house for bacteria that seems most effective in children.
Remember, vestigiality is not a case of a structure having
no function, it is when the structure does not retain the original function. The immune system is so wide-ranging that it is difficult to make a good case that the appendix has always been about that. But it does seem to act as a storehouse for bacteria that can repopulate the gut after disease.
The original function, that of a caecum in an ancestor species was subtly but importantly different: it stored materials and bacterial needed specifically for digesting cellulose in a high-plant diet. So that makes the appendix vestigial, again by definition.
So we agree? Evolutionists were wrong to declare it junk.
It would be wrong to call regulatory genes 'junk'. It would not be wrong to call large stretches of DNA 'junk DNA', as I explained.
Our eyes, eagles eyes (etc) have an inverted design that has been compared to fibre optic technology and is superior to the verted design in an octopus.
Has been compared to, eh? Superior in what way, exactly?
(Many octopus varieties are colorblind, and they most likely all have a much slower response time).
That point is not relevant to the orientation of the wiring. I did mention the inferior lens in octopi, you will recall This is not about octopus eyes in general, the claim is specific to the structure of the retina.
Finally we seem to almost agree on something! As evolutionary biologist Lyn Margulis said "Natural selection eliminates and maybe maintains, but it doesn't create.".
Yup. But natural selection can give the illusion of design, albeit the kind of design that rummages around in the shed and finds some bits of stuff that will make do as a makeshift solution.
I think the further interesting point about this, and also one we might agree on, is that so-called Theistic Evolution is utter rot. Why would a god choose such a phenomenally wasteful process as evolution by natural selection if it had humans in mind all the time? There is no guarantee that humans would appear at all. I'm sure you have no question in your mind about how humans got an immortal soul, and I'm equally clear that that concept is nonsense, but when did the Catholic church think their god specially injected a soul into a previously soul-free species of ancestor, and which ancestor was it??
Lynn Margulis is probably most famous for explaining how the mitochondria in our cells, the power stations of the cell, were originally free-living organisms that formed a symbiotic relationship by becoming housed in monocellular animals.
Your argument is another 'god of gaps' claim. (I don't understand the design, therefore evolution did it). Evolutionists of the past made the same 'god of gaps' argument about many of our organs... until science proved them wrong.
Well you can't articulate the design, can you. How did your god build a genome from dirt as described in Genesis?
For example evolutionists claimed our eye was a shoddy design...which you still seem to believe.
I don't believe the eye is a shoddy design. It carries the
illusion of shoddy design.
Science progressed... "The idea that the eye is wired backward comes from a lack of knowledge of eye function and anatomy" Opthamologist G.Marshal.
Your cited page is a brilliant set of excuses for a god that is a poor engineer. The god could do anything it wanted, right? Including redesigning the laws of physics just to make eye design appear much more elegant, or perfect even. But the whole picture is one of many compromises, each an attempt at improving some other deficit, exactly what you would expect of natural selection finding any old bits of stuff to make a ramshackle fitting that just does the job, enough of the time to get by.
Marshal's most amusing argument is that because the iris is poorly designed, it doesn't matter that the retina is badly designed.
