Junk DNA even more fully salvaged?

 More Functions Reported for Repeat “Junk” DNA


Casey Luskin June 11, 2026

A new paper in PNAS, “CTCF directly binds G-quadruplex structures to regulate genome topology and gene expression,” elaborates more functions for supposed “junk DNA” as helping to create functionally relevant structures in DNA. Last year I wrote about non-B DNA (see here and here). It doesn’t necessarily exhibit the typical double-helical DNA structure, but it can form unique shapes that contribute to a variety of important genomic functions. This new paper explores a structure called the G-quadruplex (G4s), a loop shape that often arises in DNA segments rich in guanine. The paper reports that G4s can perform a variety of functions: 

"G4 binding activities in genomic regulators of nucleosome remodeling, paraspeckle assembly, RNA splicing, and three-dimensional genome organization. Among the prominent hits, we identify the genomic architectural protein, CCCTC-binding factor (CTCF), as one of the strongest G4 binders."

The latter function is crucial, as it reflects the ability of G4 structures to regulate large-scale chromosomal structures:

"G-quadruplexes interact with several nuclear protein complexes involved in crucial genomic processes. We found that the genomic architectural protein, CCCTC-binding factor (CTCF), directly binds to G4s and this interaction is important for regulation of genome topology and gene expression. Our work uncovers the architectural roles of G4 structures in the genome and contributes important insights into G4 biology and 3D genome organization."

A Variety of Genomic Functions

Thus, these G4 structures contribute to a variety of genomic functions, and importantly they help form topologically associating domains (TADs) that control the 3D structure of the genome:

"At the scale of tens to hundreds of kilobases, the genome is further assembled into self-interacting regions known as topologically associating domains (TADs), with higher propensity of genomic interactions observed within, rather than between TADs. TADs mediate enhancer–promoter interactions and are important for cell-type specific gene expression programs. Interestingly, G4s are shown to be enriched at TAD boundaries and implicated in regulating insulation strength of TADs"

The paper proposes a model that involves “CTCF–G4 interaction in mediating long-range chromatin looping to define stable chromatin loops or boundaries of topologically associating domains (TADs).”

So Why Does This Matter?

A variety of papers note that repetitive DNA — the precise type of DNA that our junk-DNA-defending friends assure us must be functionless — is vital for forming these G4 structures:

Ambrus et al. (2006): Discusses how telomeric repeats in humans form G-quadruplexes.

Bryan (2020): Reviews how telomeric repeat DNA forms G-quadruplexes

 Waisertreiger et al. (2025):: Discusses how pericentromeric tandem repeat DNA forms G4s.

:Nakagama et al. (2006) Discusses how guanine-rich short tandem repeat DNA forms G4s.

:Piazza et al. (2017):  Zhou et al. (2014): Discusses how the repetitive DNA sequence “GGGGCC” forms G4s.

:Adrian et al. (2014):  Explains how minisatellite tandem repeat sequences contribute to G-quadruplex formation.

: Shows how a minisatellite repeat sequence forms G4s.

:  Raguseo et al. (2023): Explains how the repeat DNA sequence “GGGGCC” forms G4s.

:Bauer et al. (2011): (2011): Shows that repetitive telomeric sequences form G4s.

:Geng et al. (2024): Shows G4s are formed by repeat DNA.

These papers demonstrate that various types of repetitive DNA, including in telomeres, minisatellites, pericentromeric repeats, and other tandem repeat DNA sequences, help form G4 structures. The point being: repetitive DNA helps form non-B DNA shapes like G4s, and these G4s are crucial for defining TADs which help define the 3D structure of the genome, regulating gene expression and even defining cell types. Far from being junk, this repetitive DNA is crucial for formatting the genome.

The genome is rich in function, and we dare not simply dismiss any of it.

On Isaac Newton's Arianism

 Yes, Sir Isaac Newton held beliefs aligned with Arian theology, though he kept these views private due to their controversial nature. Arianism, based on the teachings of Arius, denies the full divinity of Jesus Christ, asserting that the Son is a created being, subordinate to God the Father. Newton’s extensive theological writings, including manuscripts like A Historical Account of Two Notable Corruptions of Scripture, reveal his rejection of the traditional doctrine of the Trinity. He argued that the concept of the Trinity was not supported by early Christian texts and was a later corruption of scripture, a position central to Arian thought.

Newton’s studies of early Church history and biblical texts led him to conclude that passages like 1 John 5:7, which supports the Trinity, were later interpolations. He believed the original Christian doctrine was closer to Arianism, emphasizing the unity and supremacy of God the Father. However, as a fellow at Trinity College, Cambridge, and a public figure, Newton was cautious, sharing his views only with close associates to avoid persecution, as Arianism was considered heretical in 17th-century England.

His theological notes, many of which were unpublished during his lifetime, confirm his sympathy for Arian ideas, though he never formally declared himself an Arian. Instead, he framed his beliefs as a return to a purer, original Christianity. For further details, Newton’s manuscripts at the National Library of Israel or the Keynes Collection at Cambridge provide primary source material.

Grok on open theism.

 Open theism, also known as open theology or free will theism, is a theological framework that emphasizes God’s relational nature and the openness of the future. It holds that God is omniscient, omnipotent, and omnibenevolent but chooses to limit His foreknowledge or control over human decisions to allow for genuine free will. Key points:

Open theism, also known as open theology or free will theism, is a theological framework that emphasizes God’s relational nature and the openness of the future. It holds that God is omniscient, omnipotent, and omnibenevolent but chooses to limit His foreknowledge or control over human decisions to allow for genuine free will. Key points:

God’s Knowledge and the Future: Open theism posits that the future is not entirely fixed or exhaustively known by God. Instead, God knows all possibilities and probabilities but leaves room for human free choices, making the future partly "open" or undetermined.

Divine-Human Relationship: God interacts dynamically with creation, responding to human actions in real-time rather than following a predetermined script. This makes prayer, decisions, and actions meaningful, as they can influence outcomes.

Biblical Basis: Proponents cite scriptures where God appears to change His mind (e.g., Exodus 32:14), expresses surprise (e.g., Jeremiah 3:7), or tests people to discover their choices (e.g., Genesis 22:12), suggesting a relational rather than deterministic view.Critiques: Critics, often from classical theism (e.g., Calvinism), argue it undermines God’s sovereignty or omniscience, claiming an all-knowing God must know the future exhaustively. Open theists counter that God’s omniscience includes all that is knowable, but an open future is inherently unknowable in detail.

Key Figures: Theologians like Clark Pinnock, John Sanders, and Gregory Boyd have been influential in developing and defending open theism.It’s a minority view within Christianity, often debated for its implications on divine providence, prophecy, and human responsibility. If you want a deeper dive into specific arguments, biblical texts, or criticisms, let me know!

Grok on the history of EVs

 The earliest electric vehicles (EVs) date back to the 19th century, predating modern gasoline cars. Here’s a concise overview:1830s: Robert Anderson, a Scottish inventor, is credited with creating one of the first crude electric carriages around 1832–1839, powered by non-rechargeable primary cells.

1840s–1880s: Inventors like Thomas Davenport and Gustave Trouvé developed early electric motors and vehicles. In 1881, Trouvé showcased an electric tricycle in Paris.

1880s–1890s: Rechargeable lead-acid batteries spurred EV development. In 1884, Thomas Parker built an electric car in England. By the late 1880s, companies like the Electric Carriage and Wagon Company in the U.S. produced electric taxis.

1890s–1900s: EVs peaked in popularity, especially in urban areas, due to their quiet operation and ease of use compared to steam or gasoline vehicles. In 1900, about 28% of U.S. cars were electric, with manufacturers like Studebaker and Columbia producing models.

Decline: By the 1910s, EVs waned due to limited battery range (20–40 miles), high costs, and the rise of affordable gasoline cars like the Ford Model T, coupled with improved road infrastructure favoring longer-range vehicles.

EVs saw a revival in the late 20th century with models like GM’s EV1 (1996), but the modern era began with the Tesla Roadster (2008) and Nissan Leaf (2010), driven by advancements in lithium-ion batteries.

ID triumps despite the scopes trial

 Despite Scopes Effect, Intelligent Design Flourishes


The Scopes “Monkey” trial of 1925 has cast a long shadow over the evolution debate in the last century, thanks in large part to the Hollywood film Inherit the Wind, which caricatured the trial and promoted stereotypes that still persist today. On a new episode of ID the Future, I continue a conversation with Dr. Casey Luskin about the long history of the Scopes effect in science and how intelligent design has managed to flourish in spite of it.

In Part 2, Dr. Luskin explains that even as Scopes stereotypes were crystallizing in the public consciousness, skepticism about the power of Darwin’s selection/mutation mechanism continued to mount, and not just in intelligent design circles. Prominent evolutionary biologists were also voicing concern about the adequacy of the modern synthesis of Darwin’s theory. And as those concerns grew louder, so did the desperate response from committed Darwinists. Luskin talks about a surge of persecutions that have been leveled against any scientist who dares to question neo-Darwinism. 

But, as Luskin notes, the intelligent design research project has gone from strength to strength in the last three decades. Much progress has been made in building a strong, cumulative case for intelligent design as the best explanation for the origin and development of life on Earth. So as the Scopes centennial gets marked with fanfare in 2025, do ID scientists get a seat at the table? Or is the spirit of Scopes still hampering scientific progress and academic freedom today? Luskin has answers. Download the podcast or listen to it here.

The state religion?

 More on Disguised Religion


Not in science or in any other context does one faith get to impose its terms on others. That sounds like common sense. But a concern about being scientifically or politically acceptable often causes us to feel intimidated into accepting disguised religious terms that are not our own, when we’re really under no obligation to do so. With that in mind, I want to highlight a post here from earlier today, “Methodological Naturalism as religion in Disguise.” 

The key point: “If the observable data points to outcomes that natural causes cannot adequately explain, then ruling out supernatural causes from the outset is not scientific humility — it’s dogma.”

A Random Example

Religion in disguise is more common than you might think. As a random example, the other day on our Seattle NPR station I was listening to an interview with a local trans activist. The activist, Danni Askini, was saying that trans identity is not a medical practice but a spiritual one. As the activist candidly said, it is a religion where the essential activity is not going to church but going to the doctor (whether for surgery or medication). I don’t think that Askini, who goes by “they/she,” had fully thought through the implications. If trans is a religion, then you don’t have the right to tell others to accept your preferred religious language, and call you “she” rather than the more biologically accurate “he,” or to adhere to your preferred framing of reality at all.

That is a scientific context, since biology is a science, but in the philosophical scientific context of methodological naturalism (MN), adherents of the dogma, whether atheists or theistic evolutionists, don’t get to dictate to others that they must accept the framing where only natural, never supernatural, causation is scientifically acceptable. We outside the walls of MN always have to bear that in mind. Mutual respect is one thing. Dictating terms is another.

The future of the net?

 

Homeostasis vs. Darwin

 Homeostasis Is More than Treading Water


If you were to watch a person treading water in a murky lake, you might assume she is standing on a shallow bottom. She might look calm and be talking to you, but below the surface a lot of kicking and stroking going on. That’s a bit like homeostasis, a broad term for maintaining internal stability in a dynamic environment. Here we will look at recent discoveries showing the complexity of systems required to keep organisms functioning while the surroundings are changing.

Frog Breath

Consider the case of a frog maintaining its breathing reflex while the temperature is dropping. Like us, it must keep the oxygen coming in and the CO2 going out, but without endothermy, breathing might drop to a standstill in the cold or accelerate too quickly when the temperature rises. What keeps the frog happily breathing?

In Current Biology, Tara A. Janes and Richard Kinkead review a study by Cannon and Santin also in Current Biology. The researchers identified specific neurons, signals and receptors involved in maintaining the rhythm. Janes and Kinkead comment that breath homeostasis is anything but boring:

Respiratory networks, like most networks, aim to maintain relative stability in their activity level over time. Traditionally, this has been described in terms of activity-dependent mechanisms where neurons respond to their own level of activity. At the cellular level, this often involves responses to intracellular calcium signallingthat occur proportional to activity. Neurons can also stabilise network function by fine-tuning ion channel density, synaptic strengths, and intrinsic excitability. 

Before Cannon and Santin’s work, they say, much of what was known about homeostatic networks came from studies on rodents which benefit from endothermy. How do frogs keep up their autonomic breathing rhythm without that luxury? Even more challenging, how do they maintain oxygen intake when undergoing metamorphosis from tadpole to adult?

A fundamental principle is that as body temperature goes down, so does metabolism and drive to breathe. Remarkably, frogs survive and thrive in the face of these environmental fluctuations by maintaining activity in the respiratory rhythm-generating networks for air-breathing. So how do they do it?

By altering temperatures in brainstem-spinal cord preparations from bullfrogs which can survive in vitro for a day, Cannon and Santin in “a clever set of experiments” found “a novel, environment-driven mechanism regulating network activity that is capable of driving compensatory changes in respiratory function in response to cold exposure.”

First, they determined that temperature alone acts as a trigger for certain changes at the cellular level. At 10°C motor activity ceased, but became hyper-excited as the temperature returned to 22°C. “This suggests that cold exposure elicits increased network excitability in an attempt to restore respiratory motor output,” the commentators say. But much more is involved: production of norepinephrine in the locus coeruleus (LC), “a compact and highly homogeneous group of neurons located rostral to the respiratory networks,” which triggers changes in calcium ion channels. 

Ensuing pharmacological experiments showed that in response to acute temperature changes, inhibition of the electrogenic Na+ pump serves as a critical transduction step, which then activates network compensation via β-adrenergic receptor signalling

And  so to keep breathing when it’s cold, a frog depends on the coordinated responses of temperature sensors, hormones, LC neurons, neural circuits, sodium pumps, receptors, calcium ions and muscles. The research does not explain everything, but

the authors propose novel ideas that are certainly worthy of further exploration. One that caught our attention is the suggestion that central respiratory circuits switch from CO2/pH-sensing to temperature-sensing as an important source of drive to breathe at cool temperatures. In this way, temperature sensitivity allows the network to restore activity under conditions where it might be needed, while maintaining the ability of the network to fall silent when it is adaptive to do so.

Speaking as air-breathers themselves, Janes and Kinkead conclude, “Despite our respiratory bias, we humbly acknowledge that neural circuits regulate other important physiological processes beyond breathing.”

Synapse Traffic Control

In my  2024 article on the synapse, I shared my bewilderment at how those nanoscopic signal transducers work and perform rapidly and reliably despite multiple transitions in information-bearing media. A new paper adds to my bewilderment by claiming that synapses bring order out of randomness. (For more on how life brings order out of chaos, see this article.)

Krisha Aghi et al., writing in Current Biology about fruit flies, find that “spatial distribution of facilitating and depressing synapses is random” and yet the neurons maintain stable transmission anyway. How?

Synaptic strength can vary greatly between synapses. Optical quantal analysis at Drosophila glutamatergic motor neuron synapses shows that short-term plasticity also varies greatly between synapses, even those made by an individual motor neuron. Strong and weak synapses are randomly distributed in the motor neuron nerve terminal, as are facilitating and depressing synapses. Although synapses exhibit highly heterogeneous basal strength at low-action potential firing frequency and undergo varied plasticity when firing frequency increases, the overall distribution of strength across synapses remains remarkably constant due to a balance between the number of synapses that facilitate versus depress and to their degree of plasticity and basal synaptic weight.Constancy in transmitter release can ensure robustness across changing behavioral conditions.

The  robustness of the transmitted signal despite individual variations in synaptic plasticity allows fruit flies to fly, but this method also enables us to live and move. How this “method in madness” mechanism is able to work automatically in the nervous system from infant in the womb to athlete to senior citizen must cause us all to stand in awe.

Clearing Up Clock Confusion

Imagine having to follow two clocks that run at different rates. It would be like trying to play drum or trumpet in Symphony No. 4 by Charles Ives, who in one movement called for two conductors waving their batons at different tempos.

Because we have minds and large brains, we humans can track lunar cycles, solar cycles, and orbital cycles simultaneously with the help of experience, language, charts, and computers. But how does a crustacean do it? Here’s a case of life cycle homeostasis. If a crustacean gets out of rhythm, it might become desiccated on rocks or fail to reproduce.

How marine species cope with both diurnal and tidal cycles is unclear. A new study in crustaceans identifies distinct brain cells that exhibit either 24- or 12.4-hour rhythms of gene expression, thus providing a mechanism for tracking multiple environmental cycles.

So begin Victoria Lewis and Patrick Emery in a Dispatch within the same issue of Current Biology. They say that the circadian clock (day/night cycle) is fairly well understood:

The nuclear accumulation and subsequent degradation of the repressor complex are dependent on kinases and phosphatases that adjust the period of the circadian pacemaker to ∼24 hours (h). The circadian clock is primarily entrained by the light–dark (LD) cycle, but also responds to the temperature cycle and other relevant cues. With the elucidation of the molecular mechanisms underlying circadian clocks comes a key question: are similar mechanisms implicated in other biological rhythms?

Indeed they are. They comment on research reported in the same issue by Oliphant et al. who “present evidence supporting the idea that the circadian clock machinery is retooled to allow marine organisms to cope with tidal cycles through dedicated brain cells.” 

The new study helps narrow down three hypotheses about how marine crustaceans can keep up with two tempos: the circadian rhythm and the circatidal rhythm. But how do the resulting proteins interact when regulated by different brain cells? “The extent of the mechanistic overlap between the two clocks,” they remark, “still needs to be determined.” Indeed, “considerable work is still needed to understand how circatidal rhythms are entrained and generated.” Yet the humble sand flea gets along without a thought.

Much More to Homeostasis

These three studies illustrate the complexity of homeostasis, but there are many thousands more that could be drawn from. Other recent examples in my pile include, in brief:

A “mitochondrial contact site and cristae organizing system” that keeps the membranes intact in these cellular powerhouses (Current Biology).
A system to prevent crowding in epithelial tissues which otherwise might cause cell damage and loss (Northwestern University Medicine).
Spatiotemporal control of mitosis by cyclin-dependent kinase (CDK) to keep order during the many rapid changes across the cell (Nature).
A relationship between the cell cycle, circadian clock, and sense of taste that can cause food to taste differently at different times of day (PNAS)
A new organelle in the cell, dubbed the hemifusome, that “could fundamentally reshape our understanding of how cells recycle their contents and sort and direct intracellular cargo” (University of Virginia School of Medicine).
Homeostasis is a tremendously varied and complex field ripe for discoveries from a design perspective. It adds an essential time dimension to irreducible complexity, revealing the interactions of multiple IC components working in cooperation to keep an organism stable in a changing environment. And so while admiring the smiling swimmer’s face above water, we must not be unaware of the vigorously beating legs and arms under the surface that are keeping her afloat.

Grok on :the Arian emperor?

Yes, Constantine the Great's son, Constantius II, was a supporter of Arianism, a theological position that differed from Nicene Christianity. Arianism, based on the teachings of Arius, held that Jesus Christ was distinct from and subordinate to God the Father, rather than being co-equal and consubstantial as defined by the Nicene Creed.Constantius II (reigned 337–361 CE) actively promoted Arian or semi-Arian doctrines during his rule, favoring bishops and policies aligned with Arianism over those adhering to the Nicene orthodoxy established at the Council of Nicaea (325 CE), which his father Constantine had supported. This stance led to tensions with Nicene Christians and influenced ecclesiastical appointments and councils during his reign, such as the Synod of Antioch (341 CE) and the Council of Serdica (343 CE), where Arian-leaning positions were often favored.
However, it’s worth noting that Constantine’s other sons, Constantine II and Constans, leaned more toward Nicene Christianity, though their reigns were shorter and less impactful on this issue. Constantius II’s support for Arianism was the most pronounced among Constantine’s heirs.If you want more details on specific events or sources, let me know!

GROK on the baptism of roman emperor constantine.


Yes, historical evidence suggests that Roman Emperor Constantine the Great was likely baptized by an Arian-leaning clergyman, Eusebius, bishop of Nicomedia, on his deathbed in 337 CE. Eusebius was a known supporter of Arianism, a theological position that viewed Jesus as subordinate to God the Father, which was deemed heretical at the Council of Nicaea in 325 CE, where Constantine had supported the orthodox Trinitarian view.However, the exact circumstances are debated. Some sources, like the 5th-century historian Socrates Scholasticus, confirm Eusebius of Nicomedia performed the baptism. Others, like Eusebius of Caesarea, a key biographer of

Constantine, are vague about the officiant’s identity. The choice of Eusebius of Nicomedia, an Arian, may reflect political or personal ties rather than Constantine’s theological stance, as he had previously backed the Nicene Creed but also sought to reconcile Arians and orthodox Christians for imperial unity.There’s no definitive evidence Constantine himself adopted Arian beliefs at the time of his baptism, but the involvement of an Arian-leaning bishop has fueled speculation about his late-life theological leanings.

On the scopes monkey trial

 A Century Later, the Spirit of Scopes Is Alive and Well


The Scopes “Monkey” Trial turns 100 this month. According to secularist legend, the Scopes trial represented a great showdown between ignorant, fundamentalist religion and enlightened, scientific progress. But what really went down in 1925? And a hundred years later, is science still suffering from the Scopes effect? On a new episode of ID the Future, Dr. Casey Luskin begins a conversation with me about the famous trial, the play and movie based on it that reinforced unrealistic stereotypes, and some of the flashpoints in science since the trial that have fanned the flames of the debate over evolution.
         Dr. Luskin first takes us back to 1925 to remind us of the basics. That year, the Tennessee state legislature passed a law that made it a misdemeanor crime to teach human evolution. An incredibly misguided move, of course — the teaching of science should never be criminalized. But that’s what they did. The ACLU recruited a public school teacher, John T. Scopes, to teach evolution so they could test the law. He was then accused of teaching human evolution and convicted of the crime. Ultimately, it went up to the Tennessee State Supreme Court, which upheld the law and found that it was not unconstitutional. 

 How Did the Trial Capture the Nation?

, this was the 1920s, when radio had first come on the scene. So the Scopes trial itself was broadcast around the United States through radio. A whole media circus descended upon the little town of Dayton, Tennessee, and the whole nation was invited to tune in. The event was framed and postured as if it was the old outdated forces of fundamentalism versus the new forces of modernism, technology, and science.

The trial itself came and went, explains Dr. Luskin, but in 1960, the stereotypes espoused by the trial would get amplified and crystallized for generations by a play and movie loosely based on the trial called Inherit the Wind. Luskin discusses how the stereotypes from Inherit the Wind became deeply embedded in the cultural psyche, setting the stage for waves of suppression and cancellation of Darwin skeptics throughout the last half century. But even as questioners of Darwin’s theory were marginalized and often silenced, real doubts in the scientific community about the power of Darwin’s selection/mutation mechanism were mounting.

Darwin bars birds from getting driver's licenses

 Birds Don’t Drive Buicks Because of … Evolution, You See


Archaeologist Sarah Newman offers the thesis that, contrary to our assumptions, animals taught humans culture. She writes at Aeon:

Many millennia before spectacular figures of horses, mammoths, lions and other animals were painted (c17,000 years ago) on the walls of the famous Lascaux cave in the Dordogne region of southwestern France, hominin artists were dragging their fingers through soft clay, pecking and scratching simple lines and circles into rock, and rubbing and dotting cave walls with red ochre. These early marks were often placed around or atop the polished surfaces and claw marks left behind by cave bears, felines and other mammals. Sometimes the human marks imitate the forms of existing scratches or smoothing made by other species. Human art, then, is part of a broader tradition of animal mark-making.

At times, this ‘parietal art’ (the name for human-made art on cave or rock walls) is so similar to animal traces that archaeologists struggle to disentangle and distinguish one from the other. In the 1960s, for example, the French prehistorian Amédée Lemozi interpreted a series of engraved lines at Pech-Merle cave in the Occitania region of southern France as a representation of a masked and wounded shaman. Lemozi saw lines piercing the figure of the shaman and pecking intended to represent wounds, leading him to suggest that the shaman was depicted undergoing a ritual death. Lemozi’s ideas were taken up by the Belgian prehistorian Lya Dams in the mid-1980s and extended into a broader exploration of wounded men in Palaeolithic art. A few years later, however, the French prehistorian Michel Lorblanchet showed that the many crisscrossing lines making up the ‘wounded shaman’ on the calcite surface of the cave were, in fact, gashes in multiple directions left by the claws of cave bears. 

“Animals taught us culture”, June 13, 2025

This sounds like a conventional case of over-interpretation on the part of Lya Dams. Now, if someone could show that the bears depicted shamans undergoing a ritual death, Newman might have a point…

Many of the bear marks, beaver logs, and bison paths that incited new human behaviours come from a time when the divide between human and nonhuman was more porous, when humans were discovering how to be human. That process of discovery was less about our species defining itself against everything else in the world than it was about interactions, observations, mimicry, creativity and experimentation. 

“Animals taught us culture”

Overall, Newman’s thesis seems to depend on the view that only the vice of human exceptionalism would cause us to see the Lascaux cave drawings as something intrinsically different from claw marks or St. Peter’s Basilica as something intrinsically different from beaver dams. 

But they are; they involve abstractions. That chasm may appear narrow to some but it is deep. No doubt, humans learned a lot by watching animals but the critical fact is that we learned fundamentally different things.

A More Measured Look

Also at Aeon, University of Sydney evolutionary biologist Antone Martinho-Truswell provides a more measured look at humans, animals, and culture:

Culture and its transmission from generation to generation is the defining feature of humanity. It is perhaps the best candidate for the thing that separates us from other beasts. Though there are other species that have been shown to hand down accumulated knowledge — including chimps, who show some evidence for cultural transmission of tool-use — no other animal approaches our ability to layer breakthrough upon breakthrough in such a complex way, and certainly no other animal does it with the conscious intent to lift future communities beyond the achievements that came before. That is a human distinction if there ever were one. 

“Empire of flight,” June 17, 2025

So, he asks, why don’t intelligent birds do the same things? “Why do they not have a market economy, with not only goods for trade, but luxury goods whose value relies on concepts rather than raw usefulness. Why don’t birds drive Bentleys?” 

He goes into a detailed explanation of how Darwinian natural selection explains it all, provided that we see its peaks as valleys instead and assume that it operates somewhat like gravity.

For a species like ours, the valley is deep and wide, driving increasingly capable brains and increasingly complex sharing of information — and presumably, creating enough gravity to draw other species in.

That hasn’t occurred.

For reptiles, fish, amphibians, cephalopods and other groups, it is not terribly surprising that they haven’t fallen down the well of complex culture in the evolutionary landscape. Their constellation of traits actually places them rather far away, in their own local minima, with the gravitational effects of human-style culture felt only distantly, if at all.

“Empire of flight”

And still no Bentleys for the birds? Martinho-Truswell blames flight:

Flight is an evolutionary black hole. It is a gravitational well with no bottom, a trait so powerfully effective at improving survival and reproduction that it plunges a species into a well of easy life and high fitness from which there is no escape. Or, to return to more conventional evolutionary language, it relieves an incomparable amount of selection pressure that might drive a species to alternative traits.

“Empire of flight”

This all seems a roundabout way of saying that humans are exceptional. And here’s the question that no one in evolutionary biology has the answer to: What is the “it” that we have and birds don’t? The conundrum of human consciousness strikes again.
