Which is the "better" explanation for the nested hierarchical structures we find all living creatures are part of--common designer or common descent?
i think everyone has heard my swapped modules to yield a chimera idea that if they existed in nature would be the end of nested hierarchies and sufficient proof that ToE is wrong.
likewise, i've posted my idea of a proposed genetic code kinds barrier widely enough that everyone here has heard of it, this also being a sufficient proof of the kinds barrier and the impossibility of common descent.
i'd like to look at another neat and interesting counterexample to swapped modules vs nested hierarchies--the w-herv that has been recruited as a placental attachment protein.
this will get you into the literature plus is interesting not like research papers *grin*

what i am curious about, is that HERV's are swapped modules, kindof. They swap not functional genes but just dna fragments (plus themselves) so that you don't see an eye protein jumping from octopus to human, let alone a complex structure. the interesting thing is what can happen to the HERV+extraneous DNA grabbed from the last cycle of incorporation into the host genome.
what happens is that the material is recruited for another totally different function. it's understandable, the operon is not being transferred but just snippets of DNA.
so nested hierarchies are not entirely isolated but what is exchanged is just dna fragments.
so still no designer swapped modules and the swapping that is being done fits nicely into common descent rather than common designer theory.
nice, fun.
i found several more nice papers on HERV-W but http://minds.wisconsin.edu/bitstream/1793/343/1/ERV+2.pdf
is particularly useful and short with pictures. *grin* the interesting observation is that the protein is being used for much the same function, to hook together cells, in the virus and in the placental tissue.
worthwhile read.

The paper quoted above proposes that placental mammals have co-opted one (or a small group of) HERV in building a connection between placenta and uterus in a way that does not compromise immunological isolation between mother and embryo. In a sense, this HERV allows the early embryo to implant into the wall of the uterus. Anti-HIV drug AZT, which is an inhibitor of reverse transcription prevents implantation of the fertilized egg, presumably by blocking the expression of the HERV.
