Nice, from the article:
The body of a tunicate seems simple, Dishaw says, but the new study shows âthis simple system has incredible complexityâ in its immune system.
Itâs starting to seem that every new paper always confirms with the Discovery Institute has known all along and the rest of us were just too stubborn to admit.
Sorry, what is it that theyâve known all along?
Its another example of irreducible complexity! Right under our noses. Canât evolve that via stepwise natural mechanisms no doubt.
It would be funny except thatâs going to be the actual article on ENV.
If bacteria has an immune system (CRISPR) arenât immune systems ancient and evolving too?
A common design would predict , now and then, immune systems that are alike in unlike creatures.
i think YEC would see the immune system as a post fall adaptation and not a god created thing yet it still , within the limits of a common blueprint, come to like results. here and there.
Ours isnât like CRISPR. It is like that of the tunicates, whose original function was clearly simply maintaining the distinction between adjoining colonies. Itâs why our immune systems donât recognize foreign antigens by themselves, but always in the context of self (altered self).
Itâs why we have enormous responses to antigens from other members of our own species, which is very counterintuitive.
What exactly does common design predict now? I wasnât aware of any particular patterns that it explains other than after the fact declaring that it predicted such all along. This example would be like finding two books written in english and find that âhey my book has chapters and your book has chapters- they must have the same author!â
âRemarkably similarâ seems to be very arbitrary and subjective. Doe these tunicates have toll-like receptors? Antibodies? MHC complexes? Do they have TNF-alpha or interferon-gamma? Complement?
I will have to comb through the original paper at some later point and see what similarities can be found.

No itâs more like my book has a chapter on downhill racing and yours has a chapter on slalom.
All immune systems are about defending against non-self. In my analogy that would represented by all sports that involve getting down snowy hills fast. There are lots of ways to do it. Some are clearly related (sports that use skis for example). Others are much less similar like inner tubing or bobsled.
I got my doctorate in a department with very broad range of subjects being researchedâecology, evolution, vertebrate and invertebrate zoology, physiology, cell biology, developmental biology, and genetics. We heard seminars in all areas. I recall at least one seminar, maybe more, on Cnidarian and tunicate immune systems. Hagfish too!
Thanks yâall for the column idea, but I donât think I would take it the direction proposed. These days, everything is complex because everything needs to be.
I see. Well in that case then its similar enough as @Robert_Byers noted to qualify for âwithin the limits of a common blueprint.â
I suggest going back:
Because what he wrote was objectively false. Under oath, he added absurd qualifications that were not present in his false statement.
I think that if go look at the transcript with your eyes open, youâll see my point and agree with Judge Jones that Behe didnât bother looking. If you go looking with your eyes closed, you wonât.
I predict the latter. Iâd love to be proven wrong.
The authors said:
The body of a tunicate seems simple, Dishaw says, but the new study shows âthis simple system has incredible complexityâ in its immune system.
So you misread their comment, thinking âincredibleâ was actually âirreducibleâ? Iâm just wondering how you made the leap from âincredible complexityâ to âirreducible complexity.â
Irreducible complexity is incredible!
