The Mysteries of Evolution: 1. Darwinian evolution is a non-random process
During my research on consciousness I have come across more than a few of the so-called mysteries of evolution mainly uttered by Richard Dawkins who seems to have no problem at all that science has not been able to explain them in terms of evolutionary processes… (More of them in my upcoming posts).
What I’ve found really interesting was Dawkins’ public statements that Darwinian evolution and its main mechanism–natural selection–are non-random.
Really? Why didn’t he say so 40 years ago? Continue reading
Human Evolution: the evidence evolves!
I see there are new fossil finds in Morocco which have been reported on the BBC. Here is the Nature Letter that reports the new find. What were modern humans up to prior to the flowering of human civilisation that left no mark prior to, lets say, ten thousand years ago? Why the large brains? Why the capacity for complex communication? Why the gap of over a quarter of a million years before the burst into human civilisation?
Two planets with life are more miraculous than one
The Sensuous Curmudgeon, who presently cannot post to his weblog, comments:
This Discoveroid article is amazing. Could Atheism Survive the Discovery of Extraterrestrial Life?. I wish I could make a new post about it. They say that if life is found elsewhere, that too is a miracle, so then you gotta believe in the intelligent designer. They say:
“The probability of life spontaneously self-assembling anywhere in this universe is mind-staggeringly unlikely; essentially zero. If you are so unquestioningly naïve as to believe we just got incredibly lucky, then bless your soul.”
Actually, “they” who posted at Evolution News and Views is someone we all love dearly, and see occasionally in the Zone — that master of arguments from improbability, Kirk Durston.
J. Warner Wallace’s eight attributes of design
Christian apologist (and former atheist) “Jim” Warner Wallace knows quite a lot about design, having earned a bachelor’s degree in design from California State University and a master’s degree in architecture from UCLA. Wallace also worked as a homicide detective for many years, in a job where he had to be able to distinguish deaths that were intentional from deaths that were not. Wallace writes well, and his Cold Case Christianity: A Homicide Detective Investigates the Claims of the Gospels (David C. Cook, 2013) is an apologetic masterpiece. So naturally, when I came across a post over at Evolution News and Views, featuring his views on Intelligent Design, I was very interested to hear what he had to say.
In his interview with Center for Science & Culture research coordinator Brian Miller, “Jim” Warner Wallace listed what he referred to as eight attributes of design. Wallace emphasized that a strong case could be made for saying that an object was designed, even on the basis of its possessing only a few of these attributes, but that when taken together, they constitute a case for design which is certain beyond all reasonable doubt. The cumulative nature of the case is what makes it so strong.
Without further ado, here are Wallace’s eight attributes of design: Continue reading
What is the Point of God
So there’s this kerfluffle surrounding a Christian school that decided to ban from the school’s graduation ceremony a teen who by all accounts, was a model student, positive leader, active church and community participant and role-model, and countless other accolades, but who apparently was “immoral” and got pregnant.
My question is, what is the point of God (or really any god) to people who feel they need to act on behalf of said God and punish people for acts that are immoral by said supposed God’s standards? Note, we’re not talking about punishing someone for a legal infraction; the principal in the case has been quite clear that the teen is being punished for being immoral. So I’m curious as to what such folks believe God’s role is or whether such folks believe God even has a role or does anything?

Is ID really a reasonable alternative to “it just happened”?
One of our regular commenters explains why they stick with ID:
ID is a perfectly reasonable alternative to “it just happened, that’s all.”
Yet that “reasonable alternative” is just “it happened like that because it was Intelligently Designed“. ID as yet has no specifics as to who, when, what, how, why etc.
So it seems to me that said commenter has just replaced “it just happened” with another phrase that means exactly the same thing but now they can be an intellectually fulfilled theist. Continue reading
Dale Tuggy’s Trinitarian challenge – and a survey
Dale Tuggy is a Professor of Philosophy at the State University of New York. He is also a podcaster and an enthusiastic blogger. Tuggy’s intellectual odyssey is an interesting one. He grew up as an evangelical who never seriously questioned the doctrine of the Trinity (that there are three persons – the Father, the Son and the Holy Spirit – in one God), until he went to graduate school. After examining various rival Christian interpretations of the Trinitarian doctrine, he came to believe that it was profoundly unbiblical, and now calls himself a Christian unitarian, who identifies the one God of the Bible (YHWH) with the Father (and not the Son or the Holy Spirit).
It is not my intention in this post to argue either for or against the doctrine of the Trinity, or to explain precisely what it means. Rather, what I intend to do is evaluate a specific argument put forward by Professor Tuggy, which is deliberately targeted at certain evangelical apologists who have recently maintained that Jesus is God tout simple – in other words, that Jesus simply is God Himself, and that Jesus and the one God are therefore numerically identical. It should be noted that most Trinitarians do not say this: for them, the term “God” designates a being (or as some would prefer to say, Being Itself), whereas the name “Jesus” refers to an incarnate Divine person (God the Son). These Trinitarians would therefore agree with the conclusion of Tuggy’s argument, which is that Jesus is not divine in the same way that the one God is.
That Dead Horse Just Won’t Stay Down
This isn’t one of the 10 unanswerable questions, but it’s still from Jonathan Wells’ book Icons of Evolution, p. 51. Wells is attempting to cast doubt on the efficacy of molecular systematics, by pointing out how silly some of the results are:
Even when different molecules can be combined to give a single tree, the result is often bizarre: A 1996 study using 88 protein sequences grouped rabbits with primates instead of rodents; a 1998 analysis of 13 genes in 19 animal species placed sea urchins among the chordates; and another 1998 study based on 12 proteins put cows closer to whales than to horses.
Of course the last example is the funniest, given the wealth of molecular and fossil data showing that cows and whales are indeed related. Continue reading
Alien
So I’ve gotten a tad bored with the discussion of macroevolution at the moment (it’s yet another rehash of the same points that keep cropping like cicada eruptions every few years. For a very similar recent exchange, look up Sal and his lungfish discussion. Or check out Things That IDers Don’t Understand, Part 1 — Intelligent Design is not compatible with the evidence for common descent – from 2012!)
So, as a public service, I figure I’d toss out a something that is a little less dramatic (on some levels) and wholly entertaining.
So I’m a big Alien fan. A fan of the original movie of that name that is and mostly a fan of the franchise that spawned from it. Big fan…HUGE! I loved the original movie (after getting the willies scared out of me the first time I saw it) because it was the only movie I’d ever seen that even remotely tried to come up with a concept of what an organism that did not develop on Earth might be like. And let’s face it, that was one cool organism they came up with!
Jonathan Wells and Homology
This is the third and last of my answers to Jonathan Wells’ 10 unanswerable questions for evolutionists.
Question 3: Homology.
Wells: Why do textbooks define homology as similarity due to common ancestry, then claim that it is evidence for common ancestry — a circular argument masquerading as scientific evidence?
This question stems from confusion on Wells’ part between how something is defined and how it is recognized, which are two quite different things. Homology is indeed defined as similarity due to common ancestry. But we don’t just label any similarity a homology and call it evidence for common ancestry. That would indeed be circular. What we really do is quite different. Similarity between the characteristics of two organisms is an observation. If the similarity is sufficiently detailed (“both are big” or “both are green” won’t do) we consider it a candidate for homology.
Jonathan Wells and Archaeopteryx
Since I’ve been asked, I’m posting another of my answers to the 10 unanswerable questions for evolutionists in Jonathan Wells’ book Icons of Evolution.
Question 5: Archaeopteryx.
Why do textbooks portray this fossil as the missing link between dinosaurs and modern birds — even though modern birds are probably not descended from it, and its supposed ancestors do not appear until millions of years after it?
What does Archaeopteryx have to be to qualify as a “link” (not a missing link, because it isn’t missing)? Wells apparently (he never really says) requires an insensible gradation of ancestors and descendants leading from an unquestioned dinosaur to an unquestioned bird, with Archaeopteryx in the middle. While that would be nice, it’s hardly necessary — and considering the quality of the fossil record, that’s lucky.
Evo-Info review: Do not buy the book until…
Subjects: Evolutionary computation. Information technology–Mathematics.
… the authors establish that their mathematical analysis of search applies to models of evolution.
I have all sorts of fancy stuff to say about the new book by Marks, Dembski, and Ewert. But I wonder whether I should say anything fancy at all. There is a ginormous flaw in evolutionary informatics, quite easy to see when it’s pointed out to you. The authors develop mathematical analysis of apples, and then apply it to oranges. You need not know what apples and oranges are to see that the authors have got some explaining to do. When applying the analysis to an orange, they must identify their assumptions about apples, and show that the assumptions hold also for the orange. Otherwise the results are meaningless.
The authors have proved that there is “conservation of information” in search for a solution to a problem. I have simplified, generalized, and trivialized their results. I have also explained that their measure of “information” is actually a measure of performance. But I see now that the technical points really do not matter. What matters is that the authors have never identified, let alone justified, the assumptions of the math in their studies of evolutionary models.a They have measured “information” in models, and made a big deal of it because “information” is conserved in search for a solution to a problem. What does search for a solution to a problem have to do with modeling of evolution? Search me. In the absence of a demonstration that their “conservation of information” math applies to a model of evolution, their measurement of “information” means nothing. It especially does not mean that the evolutionary process in the model is intelligently designed by the modeler.1

Jonathan Wells and the Cambrian explosion
In honor of Jonathan Wells’ new book, which I haven’t yet seen, I’m recycling from his first book Icons of Evolution, in which he poses 10 unanswerable questions for evolutionists. Here’s my answer to question #2: Darwin’s tree of life.
Wells: Why don’t textbooks discuss the “Cambrian explosion,” in which all major animal groups appear together in the fossil record fully formed instead of branching from a common ancestor — thus contradicting the evolutionary tree of life?
There are a great many premises hidden in this question. Wells claims that 1) textbooks don’t discuss the Cambrian explosion, 2) all major animal groups appeared during the explosion, 3) the groups were “fully formed” when they appeared, and 4) that this all somehow falsifies the idea of common descent. As we will see, none of these premises is true, so the question is pointless. It’s would be surprising if textbooks didn’t discuss the Cambrian explosion, since it’s a major event in the history of life. And in fact they do. Of ten textbooks examined by Wells, he claims that eight don’t even mention the explosion.. In fact all but one does mention it, and four of those give it more than a hundred words. Still, a hundred words isn’t much to deal with such a major event; Wells’ implication is that coverage of the explosion is being deliberately suppressed. Then again, textbooks have limited space to deal with all of the complex field of biology; an alternative explanation is that these books just have limited coverage of the history of life and of evolution in general.
Can prairie dogs talk?
Ferris Jabr has recently written a highly illuminating article for The New York Times Magazine titled, Can Prairie Dogs Talk? (May 12, 2017), on the pioneering work of Dr. Con Slobodchikoff, an emeritus professor of biology at Norther Arizona University. Professor Slobodchikoff has been analyzing the sounds of prairie dogs for more than 30 years, and he thinks that they possess a form of genuine language. Specifically, he claims that when they give alarm calls for different kinds of predators, they identify not only the type of predator, but also its size, shape, color and speed. In other words, their messages do not consist merely of nouns; instead, they are more akin to descriptive phrases. In a follow-up interview with Professor Marc Bekoff (Psychology Today, May 14, 2017), Slobodchikoff argues that since the rate at which the alarm calls are produced tends to correlate with the speed of travel of the approaching predator (hawks, for example, elicit only a single bark because they are so swift), prairie dog talk also contains something analogous to a verb in human language. Most surprising of all, prairie dogs are capable of coming up with new alarm calls for abstract objects which they have never seen before, such as an oval, a triangle, a circle, and a square. And if that were not enough, it turns out that prairie dog calls, like human language, are composed of phonemes. Indeed, Slobodchikoff even declares that prairie dogs have the most complex language of any non-human animal.
Professor Slobodchikoff contends that it is only pure prejudice on the part of “human exceptionalists” (many of whom are linguists and philosophers) that prevents scientists from describing prairie dog calls as true language, rather than mere “communication.” In addition, many people’s thinking is still influenced by Aristotle’s Scala Naturae, which ranks humans at the top, followed by “higher” mammals such as apes and then “lower” mammals such as mice (and of course, prairie dogs), with birds, reptiles, amphibians and fish lower down in the pecking order, and with insects, worms and one-celled animals at the very bottom. Such a view, argues Slobodchikoff, is speciesist and profoundly primatocentric. It is time for scientists to cast aside their prejudices and recognize that humans are not the only animals that can talk.
Is Slobodchikoff right? In today’s post, I’d like to explain why I’m inclined to be skeptical of the claim that prairie dogs are capable of anything like language.
What is consciousness? The soul vs the quantum state of particles in human brain
Recently, I have come across the 2 popular views of what consciousness is.
The spiritual or religious view that seems to rely on something immaterial, like the belief in the soul that lives on or continues to exist somewhere in the universe after the human body ceases to live and stops functioning. Continue reading
