As discussed here extensively, nothing in “evolution” makes any sense: “natural selection, fitness, speciation, human evolution, gradualism, divergence of character, UCD, TOL, etc. etc.” Not one makes sense. Meanwhile, the “evolution” argument is just one big “affirms the consequent” logical fallacy, while Paley’s excellent argument has never been overturned, and an intuitive intelligent design detector can be used to easily disprove “evolution”. Is there a need for any more proofs? Not really. Are there any other proofs? You bet. Take entropy for instance… Continue reading →

Background

For the past month or so I’ve been investigating the claim that the phylogenetic signal is evidence that a dataset shares common descent.

Supposedly, the phylogenetic signal is one of, if not the, strongest pieces of evidence for common descent. It is one of the first of the 29+ evidences for evolution offered over at Talk Origins (TO).

Quoting from the article:

The degree to which a given phylogeny displays a unique, well-supported, objective nested hierarchy can be rigorously quantified. Several different statistical tests have been developed for determining whether a phylogeny has a subjective or objective nested hierarchy, or whether a given nested hierarchy could have been generated by a chance process instead of a genealogical process (Swofford 1996, p. 504). These tests measure the degree of “cladistic hierarchical structure” (also known as the “phylogenetic signal”) in a phylogeny, and phylogenies based upon true genealogical processes give high values of hierarchical structure, whereas subjective phylogenies that have only apparent hierarchical structure (like a phylogeny of cars, for example) give low values (Archie 1989; Faith and Cranston 1991; Farris 1989; Felsenstein 1985; Hillis 1991; Hillis and Huelsenbeck 1992; Huelsenbeck et al. 2001; Klassen et al. 1991).

I’ve been skeptical of this claim. A tree is just one kind of directed acyclic graph (DAG), and my hunch is many kinds of DAGs will also score highly on metrics for phylogenetic signal. I picked one metric, the consistency index (CI), which according to Klassen 1991 is the most widely used metric. It also is the featured metric in the above TO article. Plus, it is very simple to calculate. So, I’ve focused my efforts on the CI metric. Continue reading →

Nonlin.org has a burning desire to discuss sexual selection. So, let’s.

The topic was tangential (though not entirely unrelated) to the evolutionary psychology thread. Nonlin was unable to restrain his contempt for his interlocutors, and so his final missive was guanoed. The opportunity to repost was declined, as guanoing is ‘censorship’ (in plain sight!) and a ‘white flag’ allowing nonlin to declare victory and strut around like … well … a peacock.

Let me begin with a confession. Temperamentally, I’m very much disposed to believing in angels – and aliens too, for that matter. I would certainly echo Hamlet’s famous saying, “There are more things in heaven and earth, Horatio, Than are dreamt of in your philosophy.” The notion that human beings are the most intelligent creatures in existence strikes me as a monstrous vanity.

Now, I don’t claim to know what other kinds of intelligences exist in our cosmos. But one thing I do know: both angels and aliens pose genuine conundrums for would-be defenders of the Christian faith. In a nutshell:

[For a brief explanation of my “An A-Z of Unanswered Objections to Christianity” series, and for the skeptical tone of this article, please see here. I’m starting my A-Z series with the letter H, and I’ll be zipping around the alphabet, in the coming weeks.]

In this article, I take aim at the Christian teaching that there was a special moment in history at which humans, who were made in the image of God, came into existence, and that a sharp line can be drawn between man and beast. I argue that on purely scientific grounds, it can be shown that such a view is highly unlikely. If the scientific arguments I put forward here are correct, then Christianity is in very big trouble.

The sinking of the Titanic, by Willy Stöwer, 1912.

During the past 25 years, there has been a dramatic resurgence in Christian apologetics, as many talented individuals have written books and given public speeches in defense of the Christian faith. Some of these people have even gone so far as to claim that we are now living in the Golden Age of Christian apologetics (see here, here and here). More books are being published than ever before, and the New Atheist movement, which appeared so powerful ten years ago, has largely fizzled out. The future looks good – or does it?

In this series, I’m going to explain in detail why I believe this rosy view is utterly mistaken, and why Christians are actually facing a thirty-year winter. Continue reading →

Yesterday afternoon, acting on a recommendation by evolutionary biologist Jerry Coyne, I sat down and listened to a 43-minute Scientific American podcast featuring Stanford biology professor and hard determinist Robert Sapolsky being interviewed by Robert Mirsky, on the topic, “Your brain, free will and the law.” Suffice to say that I was underwhelmed. I had high expectations, as Professor Sapolsky is not only a well-published author (whose most recent work is Behave: The Biology of Humans at our Best and Worst), but also a professor of biological sciences, neurology and neurological sciences at Stanford University and a research associate at the National Museums of Kenya. I was both disappointed and amused with what I heard: disappointed with the complete absence of any rigorous argument against the existence of free will, and amused by the fake history related by Sapolsky, in the course of his interview with Robert Mirsky. By the way, for those readers who are looking for a critique of the doctrine of free will that’s both hard-hitting and substantive, I’d recommend the online writings of physicist Sabine Hossenfelder – in particular, her articles, How to live without free will, Free will is dead, let’s bury it and The Free Will Function: Free will from the perspective of a particle physicist (but see also the conclusion to her prize-winning 2018 essay, The Case for Strong Emergence, in which she acknowledges a gap in her argument). [Full disclosure here: I have previously critiqued Dr. Hossenfelder’s arguments against free will, and although I continue to find her case less than convincing, I would now acknowledge her general point that top-down causation alone won’t rescue free will.]

Back to Sapolsky. Since he’s a professor of biology, neurology and neurosurgery, I had hoped that he would at least attempt to summarize the biological case against free will, but he didn’t. He alluded to experiments by Benjamin Libet, noted in passing that there were multiple interpretations of these experiments, and then proceeded to his central argument: the “shrinking pie” argument, which relied on a very heavy dollop of fake history. In a nutshell: science has already shown that we are not responsible for X, Y and Z, so in time, science will show that we are not responsible for any of our actions. (By the way, Sapolsky is a hard determinist, who has no time for compatibilism and who eschews any notions of personal responsibility for our actions: as he puts it in his podcast, “We have no control, ultimately, over anything we do… We have no agency, and the criminal justice system does not make any sense at all.”)

So, what’s wrong with the “shrinking pie” argument? Everything.

‘Stay the fuck home’. A less effective means of gaining general co-operation from the instinctively anti-establishment would be hard to imagine. How about you get the fuck out of my face? Our more formal UK government messaging has plumped for the ‘will-no-one-think-of-the-the-children’ emotional arm-twist of ‘Stay Home, Protect The NHS, Save Lives’. This appears at the foot of the rash of notices that has appeared all over my own rural region requesting people to approach a farm gate on a public path as they would open heart surgery, and disinfect or wear gloves before touching. After a day slapping cows’ backsides (I am hazy on the details of the profession!), it would be too much to expect farmers to take responsibility for their own biosecurity, and wash their own hands before dining.
