BoJ: "Even renowned people can get things wrong."
COMMENT: True! After all, I have often cited numerous renowned materialist scientists and philosophers who I claim get it wrong. But then, I provide full explanations, including arguments and citations.

BoJ: "The controversies in biological evolution are nibbling around the edges. The basic tenets (that different species arose through mutations of earlier species, when the particular mutations led to enhanced survivability in the particular environment the organisms encountered)."

COMMENT: Although there is no longer a debate about the *fact* of evolution, the remaining controversies are NOT just "nibbling around the edges." The nature, role, and "mechanism" of natural selection, as espoused by "Neo-Darwinism" in particular are hotly debated, and for the most part rejected as at best grossly incomplete.
Here is a quote from a "renowned" biologist. (For what that might be worth)
"Since Darwin, we turn to a single, singular force, Natural Selection, which we might as well capitalize as though it were the new deity. Random variation, selection-sifting. Without it, we reason, there would be nothing but incoherent disorder."
"I shall argue in this book that this idea is wrong. For, as we shall see, the emerging sciences of complexity begin to suggest that the order is not all accidental, that vast veins of spontaneous order lie at hand. Laws of complexity spontaneously generate much of the order of the natural world. It is only then that selection comes into play, further molding and refining. Such veins of spontaneous order have not been entirely unknown, yet they are just beginning to emerge as powerful new clues to the origins and evolution of life."
(Stuart Kauffman, *At Home in the Universe: The Search for the Laws of Self-Organization and Complexity* (1995) p.8 (Incidentally, for those who have heartburn over older citations, Kauffman's views have not changed, after multiple follow-up books and peer-reviewed articles.)
In other words, "Natural Selection" "the new deity" of biology isn't enough, or even primary in explaining evolution. Evolution must be supplemented by further, unknown laws of self-organization and complexity, which to this day remain unknown and mysterious, despite decades of heroic effort by Kauffman and others to scientifically pin them down.

BoJ: "We now know the mechanism for how mutations get passed on (DNA and genes) which Darwin did not know. We have filled in a lot of the details on evolution, and there are many more details yet to be filled in, but in broad strokes, Darwin was basically right. He either guessed wrong, or didn't guess at all on some of the details. That's how science works."
COMMENT: OK. What is the mechanism? Explain it for me, in terms as would be acceptable to a good mathematician or engineer. How are we evolutionist to understand "mechanism." Don't just talk about genetic mutations and natural selection and announce you have provided a "mechanism." The problem is that, if you want something theoretically meaningful, you have to get from genetic mutation, to phenotype, to survival advantage, to population genetics, by explaining actual biology beyond mere abstract terminology. Until then, all you have is natural history, not a theory, much less an explanation of natural selection. Here is a quote from the Fodor book cited above. It is very straightforward logic:
"Natural selection theory is often said to provide a mechanism for the evolution of phenotypes. That, however, is precisely what it doesn't do. What explains why there are the phenotypes there are is not natural selection but natural history. It is, as we've been seeing, just a truism that birds are adapted to their airy ecology. But what isn't a truism is that the bird's wings are the mechanism of this adaptation. If, in the ecology they occupy, birds with wings are better off than birds without them, there must be something about the birds, or about the ecology, or about the two together, in virtue of which birds with wings are better off in that ecology than birds without them. That's just a routine application of the principle of sufficient reason; as such it's true a priori and applies, sight unseen, to birds that have wings, fish that have gills, germs that are resistant to penicillin, and so forth indefinitely. So, as on politician asked about another politician, 'where's the beef?'
"The beef comes not from adaptation but from the details of natural history. You have to look into the structure of niches (how birds manage to fly; how fish manage to breathe under water; whatever). That's how to find out how having wings conduces to the fitness of birds. It's natural history that gets you out of the circle that plagues selection theory, in which 'niche' is defined in terms of 'adaptation' and 'adaptation' is defined in terms of 'niche.'"
In other words, evolution and Darwinism (new or old) is NOT a "mechanism" that explains adaptation. Evolution is an account of natural history! Birds may have wings, and fish may have gills because of evolutionary processes that happened to equip them with these features, but they didn't "adapt" to any environment, or niche, both of which were just there, as part of their own natural history.
So again, where is the mechanism? Why isn't Evolution just the result of what historically happened when some organism was faced with some environment and, for any number of reasons, managed to survive or not? Population genetics, as it relates to phenotypes, is then just statistics about the biosphere, without any need for "natural selection" or "adaptation." Nature doesn't "select" anything, much less select for "traits."
The above arguments refute Neo-Darwinian "mechanism" but, of course, not evolution itself. Moreover, it is consistent with Evo-Devo (Evolutionary Development), wherein developmental processes and other contingencies shape phenotypes and survival, without any Darwinian adaptationist explanation, except sometimes as an afterthought, or homage to entrenched Darwinian tradition.
Now, that should disrupt your comfort zone of evolutionary platitudes. Any substantive response? It is a very simple set of question(s), "Where is the "mechanism" in Darwinism?" What exactly is "natural selection?" Who is 'selecting' what? Why is evolution not simply the natural history of living organisms? And, finally, how does increasing biological complexity fit into this natural history? More laws?
You need a bit more nibbling around the literature.
