Sherlock Holmes wrote: ↑Tue Jan 25, 2022 10:56 amFirst you claim there are absolutely no controversies within evolution and now you change that and claim that you know of no "papers challenging evolution" which must, I assume, in your mind, be your definition of "controversy".
I haven't changed anything. I've never claimed that there were no controversies within evolution, I've claimed that there's no scientific controversy about whether or not evolution in fact happened. The reason I'm specific about my definition is because of your repeated attempts to characterize a religious controversy as a scientific controversy.
Sherlock Holmes wrote: ↑Tue Jan 25, 2022 10:56 amA controversy is any kind of disagreement, alternate views and opinions among people with some expertise in a field, nothing to do with "papers", yes some controversies may manifest in a peer reviewed journal but that is not a necessary condition for a dispute to be a controversy!
It is for it to be a
scientific controversy.
Sherlock Holmes wrote: ↑Tue Jan 25, 2022 10:56 amSo let me ask a different way - are there any scientists who question the efficacy of evolution? The answer is a very obvious yes, this is trivial to discover too so why you are struggling I can't imagine.
What is it that you think I'm struggling with? That there are people with scientific credentials that are also creationists? I came to grips with that a long time ago. Being smart doesn't make one impervious to being wrong. I'm the one that mentioned Linus Pauling, remember?
Sherlock Holmes wrote: ↑Tue Jan 25, 2022 10:56 amThe
Dissent from Darwin site publicly identifies hundreds and hundreds of researchers, professors and other specialists who say exactly that, so there is controversy, right there in front of your eyes, why can't you just admit it?
When they have collectively worked up a scientific basis for that controversy, then we'll have something to work with. I admit it.
Spiders. I have been since I was little. Weird.
Sherlock Holmes wrote: ↑Tue Jan 25, 2022 10:56 amMoreover let me say that any discipline that claims to free from controversy is by definition a dead discipline, controversy and dissent and necessary, normal and nothing to be afraid of unless one has something to lose.
What is your thing with fear all of a sudden? Does emotional language sometimes help hide your attempts at equivocation?
Sherlock Holmes wrote: ↑Tue Jan 25, 2022 10:56 amSo, of course there's controversy and if you refuse to admit that then you'll start to lose my respect.
Oh, no!
In case you haven't noticed, your attempts to recast this as a purely rhetorical debate haven't really gained you much. Not only have you apparently no evidence to present for anything, but it's also apparent that you didn't really understand the one book on the subject that you've read. If you did, you presumably wouldn't have overextended your own argument so badly right out of the gate. Meyer's book doesn't even
challenge evolution so much as it simply presents a gap into which God (sorry, "the intelligent designer") might fit. Even at that, Meyer still had to dismiss phylogenetic data in the minds of his readers for the gap to seem large enough. This brings me to another point that I feel that I have to make at this point, even if it's a bit of a tangent:
Not everybody's bluffing.
There is no shortage of internet debates, particularly involving science and religion, in which neither participant really understands the subject matter. A lot of those end up turning into games of chicken, where both sides try to present the appearance of expertise without getting called on it. That works when the opponents have roughly the same level of understanding of the subject and if you're just playing the odds, there's a pretty good chance that's true any given time. Even the best odds aren't a sure thing, though, and you sometimes crap out.
Sherlock Holmes wrote: ↑Tue Jan 25, 2022 10:56 amIt comes as something of a shock that someone who claims to be educated and more familiar than most with a subject is unaware of the various controversies present, I can only say that you are either very selective in what information you consume (that is filtering out anything that might be controversial) or do not understand what a controversy is.
You crapped out.
Let's discuss some controversies, shall we? None of the
actual scientific controversies surrounding evolution call into question whether or not evolution happened or even broadly how, but unfortunately for you, they're what we have to work with.
One of the controversies mentioned by Meyer (so you should be aware of it) is whether and to what extent a "molecular clock" can be established and calibrated to give us information that we can't get from fossils alone. It certainly works within small clades and sometimes even within larger ones, nearly always allowing us to accurately estimate divergence times at the genus level and quite often between families or even orders. The "controversy" isn't whether genetic differences accumulate at consistent rates for closely related organisms or whether those rates themselves begin to diverge, but
why those rates diverge. If we can narrow down exactly what variables are responsible, we can estimate the divergences themselves, allowing a much more accurate determination of when various clades diverged from each other. Various causes have been proposed, like organism size, genome length, reproduction rate, and even things like local climate conditions. Researchers have identified correlations with all of these, but nobody has thus far been able to come up with a synthesis that shows enough predictive power to be useful. Individual researchers have ideas and particular directions for their research, but there's no consensus. It's a
controversy.
Another controversy is how to relate phylogenies generated from nuclear genes to those generated with mitochondrial data. You see, mitochondrial data don't always result in exactly the same trees as nuclear data, even when both sets of data are extremely robust. Most of the differences are at the species or genus level, indicating that the problem is sometimes just
incomplete lineage sorting, but that's not always the case. Mitochondrial genes are obviously passed on to offspring differently than nuclear genes. Mitochondria aren't affected by meiosis and genetic reassortment, but are (with a few exceptions) inherited entirely from the mother. In most cases, the lineage data preserved in the DNA will average out so that the trees appear the same, but not always. The controversy is over how to interpret these differences. For one thing, mitochondrial DNA is easier to replicate and sequence (there are hundreds of mitochondria per cell, compared to a single set of nuclear DNA). For another, mitochondrial genes are highly conserved, allowing comparison between even distantly related organisms. The controversy is that some researchers have claimed that the mitochondrial tree is merely a proxy for the nuclear tree because the nuclear genes are primarily responsible for the traits upon which natural selection acts. The argument is that while the mitochondrial data show a valid pattern of descent, that pattern can be slightly different than the true evolutionary pattern as preserved in the nuclear DNA. That would mean, then, that the many detailed, species-level phylogenies generated with mitochondrial data can't be definitive until verified with nuclear DNA. Those that work predominantly with mitochondrial data disagree. It's a
controversy.
Now, let's go back to your rhetorical argument. Your claim is that I apparently either missed or filtered out other "controversies" within the literature that are somehow important to the very nature of evolution itself. The question that raises, though, is if you can't name any of those controversies from the literature, upon what are you basing the accusation that I'm somehow "filtering" the results? It's possible that I am, but if you can't find them and nobody else can find them, how does that advance your argument to anything beyond speculation?
At some point, you should probably put your money where your mouth is.

Lest you've forgotten, Meyer himself took a whole chapter to explain why science should be redefined so that his controversy can be called "science."
Here we go again, the
popularity of evolution is its best defense!
Is that what my defense is? I'm pretty sure it's not, because even that would oversell your argument. My defense is that book reviews aren't evidence of a scientific controversy. Even a thousand reviews, while not nothing, don't rise to the evidentiary power of one paper.
Sherlock Holmes wrote: ↑Tue Jan 25, 2022 10:56 amI just showed you Meyer's book and one (of the many) comments by academics on his book, that admit he is identifying a problem in evolution. I have previously showed you the Dissent from Darwin lists of over 1,000 scientists, professors and academics who dispute the efficacy of evolution.
Your book reviewer isn't
admitting a problem. He is an author for the Discovery Institute himself. Instead of
admitting a problem, he's advancing his own position.
Sherlock Holmes wrote: ↑Tue Jan 25, 2022 10:56 amSo how can you claim I am not providing evidence? the evidence is easily found, in Meyer's book, in many other articles and books.
"How can you claim I haven't given you a nickel? The nickel's right there at the bottom of that well!"
Each time you've even alluded to anything specific that you might be willing to defend, you've failed to defend it. Your only argument seems to be that somebody, somewhere made an argument that you agree with, but you can't even articulate what it is specifically you agree with or why. Everyone here has tried in good faith to engage with what little you've provided, but yet your claim is that we're ignoring your evidence or, most recently, frightened of your raw intellectual power.
Sherlock Holmes wrote: ↑Tue Jan 25, 2022 10:56 amSo there is evidence and plenty of it but if you live in a world where controversy does not exist, where no "real" scientists question Darwin, then of course you'll never see the evidence, you'll never comprehend it.
Yes. I'm clearly to be pitied.
