It appears that folks here do not understand intelligent design. Yes, it has been seized upon by religious folks who see it as a defense of their faith, but the school of thought is rooted entirely in sound science. Specifically, it addresses such fatal flaws in macroevolution as parallel development of indetical features down separate "evolutionary lines;" irreducible complexity (in which a collection of separate novel features have no reason to have been "selected" individually, in that they only provide an advantage when taken as a whole; and the chromosomal barrier for species that reproduce sexually (what does something with a new number of chromosome pairs or different chromosomal configuration of critical genes mate with in order to propagate the "new" species or variant?).
I find the infighting of members of the Christian faith here distasteful. I am also shocked that a person would have his account suspended for questioning papal infallibility in the midst of a series of posts calling into question the theology of others either espousing or rebutting intelligent design. Should I assume that there is a theological bias here, or was there more going on than meets the eye?
Chromosomal mutations may create sudden reproductive isolation, and often reduce fertility to some extent, but not necessarily so. Many chromosomal mutants are still fertile with non-mutants, and many species of Equids (horses) can be hybridized despite having different chromosome numbers.
