Then what was On the Origin of Species about? Never mind.

Readers may recall that New Scientist published an article some days ago on 13 ways we need to “rethink the theory of nature.”

Their Number 5 rethink is … species don’t really exist:

Most of the article is paywalled but here’s the gist of #5:

In principle, advances in genetic sequencing could have helped by indicating how genetically distinct different groups of organisms are and how long ago lineages diverged. But sequencing has arguably made the problem worse by revealing that interbreeding – more technically, introgression – between closely related “species” is common across the tree of life. “It does seem to be the rule, not the exception,” says Michael Arnold at the University of Georgia in Athens. Indeed, evidence of introgression stretches right to our front door: our ancestors interbred with various ancient hominins that might, in the eyes of some, count as distinct species. – Colin Barras

Michael Le Page , Colin Barras , Richard Webb , Kate Douglas and Carrie Arnold, “Evolution is evolving: 13 ways we must rethink the theory of nature” at New Scientist (September 23. 2020)

The mess around speciation is actually much worse than New Scientist currently discusses but a fuller exposition would require more space than is available, what with thirteen items on the rethink list. Let’s hope for a thirteen-item list on speciation alone.


See also: (Reformed) New Scientist 4: There is more to inheritance than just genes. At New Scientist: “Subsequent studies in plants and animals suggest that epigenetic inheritance is more common than anyone had expected. Whatʼs more, compared with genetic inheritance, it has some big advantages. Environments can change rapidly and dramatically, but genetic mutations are random, so often require generations to take hold.” Just think, within a few years, genetics might start to make some sense. You’ve got to hand it to the New Scientist gang; when they rethink, they really do.

(Reformed) New Scientist 3: The selfish gene is no longer cool. At New Scientist: “Some researchers think the solution lies in an idea called cultural group selection. Forget shared genes, they argue: selection can favour cooperative groups if the people within them share enough culture. ” Darwin has left the building and returned to his estate.

(Reformed) New Scientist 2: Evolution shows intelligence. At New Scientist: “‘Maybe, evolution is less about out competing others and more to do with co-creating knowledge,’ says Watson.” That really is a radical idea. Radical yes, but it really is a good idea. We find it hard to improve on. The only thing we can think of is, keep the “intelligent” part in your description of nature and add “design.”

(Reformed) New Scientist 1 on the genome: Not destiny. Sure but then what about the famous twin studies that were supposed to prove so much about human nature? No? Then it’s probably best for the New Scientists to just get out of the “gene for that” hell while they can.

and

At New Scientist: We must rethink the (Darwinian) theory of nature. If by “our greatest theory of nature,” the writers mean textbook Darwinism, well the new concepts they list are destroying it. What becomes of “natural selection acting on random mutation” if a variety of means of evolution are “natural,” mutations are not necessarily random, genes aren’t selfish and don’t come only from parents, and the fittest don’t necessarily survive? Just for a start…

___ Speciation Problems
“Biologic species” does not have a satisfactory definition. Most often “species” is defined as “the largest group of organisms in which two individuals can produce fertile offspring, typically by sexual reproduction”. The fertility “barrier” is however arbitrary, inadequate for closely related species, and irrelevant to the vast group of asexually reproducing organisms. Since organisms do not come with tree of life place cards, not just species classification but also taxonomy in general is more or less arbitrary as shown by grouping issues and the frequent revisions to its structure. Darwin admitted in his “Origin of Species”: “I look at the term species, as one arbitrarily given for the sake of convenience to a set of individuals closely resembling each other.” (p52) and “We shall have to treat species in the same manner as those naturalists treat genera, who admit that genera are merely artificial combination made for convenience.” (p485) http://nonlin.org/speciation-problems/

The problem of defining exactly what a species is is far more problematic for Darwinists than New Scientist let on with their example of interbreeding. For instance,
What is a species? The most important concept in all of biology is a complete mystery – July 16, 2019 Excerpt: Enough of species? This is only the tip of a deep and confusing iceberg. There is absolutely no agreement among biologists about how we should understand the species. One 2006 article on the subject listed 26 separate definitions of species, all with their advocates and detractors. Even this list is incomplete. The mystery surrounding species is well-known in biology, and commonly referred to as “the species problem”. Frustration with the idea of a species goes back at least as far as Darwin.,,, some contemporary biologists and philosophers of biology have,,, suggested that biology would be much better off if it didn’t think about life in terms of species at all.,,, https://theconversation.com/what-is-a-species-the-most-important-concept-in-all-of-biology-is-a-complete-mystery-119200
In fact, as Aarceng alluded to, Charles Darwin himself admitted that he did not have a rigid definition for what the term ‘species’ actually meant when he stated that, “I look at the term species as one arbitrarily given, for the sake of convenience.,,,”
“I look at the term species as one arbitrarily given, for the sake of convenience, to a set of individuals closely resembling each other, and that it does not essentially differ from the term variety, which is given to less distinct and more fluctuating forms. The term variety, again, in comparison with mere individual differences, is also applied arbitrarily, for convenience’s sake.” – Charles Darwin
In fact, the problem of defining exactly what a species is is inherent to the entire reductive materialistic foundation of Darwinian evolution itself:
Darwin, Design & Thomas Aquinas The Mythical Conflict Between Thomism & Intelligent Design by Logan Paul Gage Excerpt:,,, In Aristotelian and Thomistic thought, each particular organism belongs to a certain universal class of things. Each individual shares a particular nature—or essence—and acts according to its nature. Squirrels act squirrelly and cats catty. We know with certainty that a squirrel is a squirrel because a crucial feature of human reason is its ability to abstract the universal nature from our sense experience of particular organisms. Denial of True Species Enter Darwinism. Recall that Darwin sought to explain the origin of “species.” Yet as he pondered his theory, he realized that it destroyed species as a reality altogether. For Darwinism suggests that any matter can potentially morph into any other arrangement of matter without the aid of an organizing principle. He thought cells were like simple blobs of Jell-O, easily re-arrangeable. For Darwin, there is no immaterial, immutable form. In The Origin of Species he writes: “I look at the term species as one arbitrarily given, for the sake of convenience, to a set of individuals closely resembling each other, and that it does not essentially differ from the term variety, which is given to less distinct and more fluctuating forms. The term variety, again, in comparison with mere individual differences, is also applied arbitrarily, for convenience’s sake.” Statements like this should make card-carrying Thomists shudder.,,, The first conflict between Darwinism and Thomism, then, is the denial of true species or essences. For the Thomist, this denial is a grave error, because the essence of the individual (the species in the Aristotelian sense) is the true object of our knowledge. As philosopher Benjamin Wiker observes in Moral Darwinism, Darwin reduced species to “mere epiphenomena of matter in motion.” What we call a “dog,” in other words, is really just an arbitrary snapshot of the way things look at present. If we take the Darwinian view, Wiker suggests, there is no species “dog” but only a collection of individuals, connected in a long chain of changing shapes, which happen to resemble each other today but will not tomorrow. What About Man? Now we see Chesterton’s point. Man, the universal, does not really exist. According to the late Stanley Jaki, Chesterton detested Darwinism because “it abolishes forms and all that goes with them, including that deepest kind of ontological form which is the immortal human soul.” And if one does not believe in universals, there can be, by extension, no human nature—only a collection of somewhat similar individuals.,,, https://www.touchstonemag.com/archives/article.php?id=23-06-037-f
As should be needless to say, the inability for a supposedly scientific theory, (a supposedly scientific theory that seeks to explain the “Origin of Species” in the first place), to clearly define exactly what a species actually is is a clear indication that that supposedly scientific theory cannot possibly be the correct ‘scientific’ explanation for the “Origin of Species” in the first place! Darwinists, besides being unable to define exactly what the term species actually means, also have no evidence for the ‘blending together of characteristics’, as would be predicted under the assumption of ‘continual gradual transformations of ‘species’ into new ‘species’ (whatever the term ‘species’ is suppose to mean for a Darwinist) As Stephen Meyer explained, “the differences in form between any member of one phylum and any member of another phylum are vast, and paleontologists have utterly failed to find forms that would fill these yawning chasms in what biotechnologists call “morphological space.”
“Over the past 150 years or so, paleontologists have found many representatives of the phyla that were well-known in Darwin’s time (by analogy, the equivalent of the three primary colors) and a few completely new forms altogether (by analogy, some other distinct colors such as green and orange, perhaps). And, of course, within these phyla, there is a great deal of variety. Nevertheless, the analogy holds at least insofar as the differences in form between any member of one phylum and any member of another phylum are vast, and paleontologists have utterly failed to find forms that would fill these yawning chasms in what biotechnologists call “morphological space.” In other words, they have failed to find the paleolontogical equivalent of the numerous finely graded intermediate colors (Oedleton blue, dusty rose, gun barrel gray, magenta, etc.) that interior designers covet. Instead, extensive sampling of the fossil record has confirmed a strikingly discontinuous pattern in which representatives of the major phyla stand in stark isolation from members of other phyla, without intermediate forms filling the intervening morphological space.” Stephen Meyer – Darwin’s Doubt (p. 70) “In other words, the morphological distances — gaps — between body plans of crown phyla were present when body fossils first appeared during the explosion and have been with us ever since. The morphological disparity is so great between most phyla that the homologous reference points or landmarks required for quantitative studies of morphology are absent.” Erwin and Valentine (p. 340)
Here is an interesting quote from a researcher who, during working for his PhD thesis, was ‘surprised’ to find ‘Distinct kinds’ instead of a ‘blending together of characteristics as would be expected under Darwinian presuppositions. He even states “this was the common experience of experts in every area of systematic biology. ”
“For all the diversity of species, I found the cichlids to be an unmistakably natural group, a created kind. The more I worked with these fish the clearer my recognition of “cichlidness” became and the more distinct they seemed from all the “similar” fishes I studied. Conversations at conferences and literature searches confirmed that this was the common experience of experts in every area of systematic biology. Distinct kinds really are there and the experts know it to be so. – On a wider canvas, fossils provided no comfort to evolutionists. All fish, living and fossil, belong to distinct kinds; “links” are decidedly missing.” Dr. Arthur Jones – did his Ph.D. thesis in biology on cichlids – Fish, Fossils and Evolution – Cichlids at 29:00 minute mark (many examples of repeated morphology in cichlids) – video http://edinburghcreationgroup.org/video/14
As far as genetics is concerned, a far easier way to clearly demarcate species from one another, (rather than just sequencing genomes with the hidden assumption that all species are related via common descent as Darwinists currently assume when they sequence genomes), is to look at alternative splicing patterns and mitochondria DNA:
Evolution by Splicing – Comparing gene transcripts from different species reveals surprising splicing diversity. – Ruth Williams – December 20, 2012 Excerpt: A major question in vertebrate evolutionary biology is “how do physical and behavioral differences arise if we have a very similar set of genes to that of the mouse, chicken, or frog?”,,, A commonly discussed mechanism was variable levels of gene expression, but both Blencowe and Chris Burge,,, found that gene expression is relatively conserved among species. On the other hand, the papers show that most alternative splicing events differ widely between even closely related species. “The alternative splicing patterns are very different even between humans and chimpanzees,” said Blencowe.,,, http://www.the-scientist.com/?articles.view%2FarticleNo%2F33782%2Ftitle%2FEvolution-by-Splicing%2F Sweeping gene survey reveals new facets of evolution – May 28, 2018 Excerpt: Darwin perplexed,,, And yet—another unexpected finding from the study—species have very clear genetic boundaries, and there’s nothing much in between. “If individuals are stars, then species are galaxies,” said Thaler. “They are compact clusters in the vastness of empty sequence space.” The absence of “in-between” species is something that also perplexed Darwin, he said. https://phys.org/news/2018-05-gene-survey-reveals-facets-evolution.html
Moreover, when the genetic evidence we now have from sequencing the nuclear DNA itself is compared, in a unbiased manner, among various models, (instead of just assuming the Darwinian model to be true from the get go), then the Darwinian model fails. And it fails BIG TIME when compared to the 'design model':
New Paper by Winston Ewert Demonstrates Superiority of Design Model - Cornelius Hunter - July 20, 2018 Excerpt: Ewert’s three types of data are: (i) sample computer software, (ii) simulated species data generated from evolutionary/common descent computer algorithms, and (iii) actual, real species data. Ewert’s three models are: (i) a null model which entails no relationships between any species, (ii) an evolutionary/common descent model, and (iii) a dependency graph model. Ewert’s results are a Copernican Revolution moment. First, for the sample computer software data, not surprisingly the null model performed poorly. Computer software is highly organized, and there are relationships between different computer programs, and how they draw from foundational software libraries. But comparing the common descent and dependency graph models, the latter performs far better at modeling the software “species.” In other words, the design and development of computer software is far better described and modeled by a dependency graph than by a common descent tree. Second, for the simulated species data generated with a common descent algorithm, it is not surprising that the common descent model was far superior to the dependency graph. That would be true by definition, and serves to validate Ewert’s approach. Common descent is the best model for the data generated by a common descent process. Third, for the actual, real species data, the dependency graph model is astronomically superior compared to the common descent model. Where It Counts Let me repeat that in case the point did not sink in. Where it counted, common descent failed compared to the dependency graph model. The other data types served as useful checks, but for the data that mattered — the actual, real, biological species data — the results were unambiguous. Ewert amassed a total of nine massive genetic databases. In every single one, without exception, the dependency graph model surpassed common descent. Darwin could never have even dreamt of a test on such a massive scale. Darwin also could never have dreamt of the sheer magnitude of the failure of his theory. Because you see, Ewert’s results do not reveal two competitive models with one model edging out the other. We are not talking about a few decimal points difference. For one of the data sets (HomoloGene), the dependency graph model was superior to common descent by a factor of 10,064. The comparison of the two models yielded a preference for the dependency graph model of greater than ten thousand. Ten thousand is a big number. But it gets worse, much worse. Ewert used Bayesian model selection which compares the probability of the data set given the hypothetical models. In other words, given the model (dependency graph or common descent), what is the probability of this particular data set? Bayesian model selection compares the two models by dividing these two conditional probabilities. The so-called Bayes factor is the quotient yielded by this division. The problem is that the common descent model is so incredibly inferior to the dependency graph model that the Bayes factor cannot be typed out. In other words, the probability of the data set, given the dependency graph model, is so much greater than the probability of the data set given the common descent model, that we cannot type the quotient of their division. Instead, Ewert reports the logarithm of the number. Remember logarithms? Remember how 2 really means 100, 3 means 1,000, and so forth? Unbelievably, the 10,064 value is the logarithm (base value of 2) of the quotient! In other words, the probability of the data on the dependency graph model is so much greater than that given the common descent model, we need logarithms even to type it out. If you tried to type out the plain number, you would have to type a 1 followed by more than 3,000 zeros. That’s the ratio of how probable the data are on these two models! By using a base value of 2 in the logarithm we express the Bayes factor in bits. So the conditional probability for the dependency graph model has a 10,064 advantage over that of common descent. 10,064 bits is far, far from the range in which one might actually consider the lesser model. See, for example, the Bayes factor Wikipedia page, which explains that a Bayes factor of 3.3 bits provides “substantial” evidence for a model, 5.0 bits provides “strong” evidence, and 6.6 bits provides “decisive” evidence. This is ridiculous. 6.6 bits is considered to provide “decisive” evidence, and when the dependency graph model case is compared to comment descent case, we get 10,064 bits. But It Gets Worse The problem with all of this is that the Bayes factor of 10,064 bits for the HomoloGene data set is the very best case for common descent. For the other eight data sets, the Bayes factors range from 40,967 to 515,450. In other words, while 6.6 bits would be considered to provide “decisive” evidence for the dependency graph model, the actual, real, biological data provide Bayes factors of 10,064 on up to 515,450. We have known for a long time that common descent has failed hard. In Ewert’s new paper, we now have detailed, quantitative results demonstrating this. And Ewert provides a new model, with a far superior fit to the data. https://evolutionnews.org/2018/07/new-paper-by-winston-ewert-demonstrates-superiority-of-design-model/
This is all good, clean, science and if Darwinian evolution were a normal science that was subjected to rigorous testing, instead of basically being a unfalsifiable religion for atheists, the should count as yet another (VERY) powerful falsification of Darwinian evolution. Verse
