Chicken antibodies were studied, and discussed by the article, which
ends with these paragraphs:
"The chicken antibody was likened by fellow researcher Dr Alex Taylor
to a living fossil - "Finding out that it has an ancient past is like
turning up a coelacanth in your garden pond. By studying this
molecule, we can track the evolution of allergic reactions back to at
least 160 million years ago."
"Prof Brian Sutton, head of the laboratory where the work was done
said: "It might be that there was a nasty bug or parasite around at
the time that meant that humans needed a really dramatic immune
response and so there was pressure to evolve a tight binding antibody
like IgE.
" "The problem is that now we've ended up with an antibody that can
tend to be a little over enthusiastic and causes us problems with
apparently innocuous substances like pollen and peanuts, which can
cause life-threatening allergic conditions." "

It always seems amazing to me that the latest anti-evolutionary fervor
arose at a time when we're being overwhelmed with the evidence of
molecular (non-teleological) evolution, and increasing ability to make
use of that information.
The good thing is that about every week we get more substantial
evidence that life evolved, without any indication of intelligence
being involved, while the same blank denial is all that the IDiots can
muster.
