Prompt: Provide the source for these words. “Yale University’s David Gelernter—one of America’s most respected computer scientists—has become an unexpected but influential critic of Darwin’s evolutionary theory. His shift is not ideological but analytical: after decades of studying complex systems, probability, and biological discoveries, Gelernter concluded that Darwin’s model no longer fits the scientific evidence. As he famously stated, “The origin of species is exactly what Darwin cannot explain.”
Response: The sentence you quoted — “The origin of species is exactly what Darwin cannot explain” — comes from a 2019 essay by Yale computer scientist David Gelernter titled “Giving Up Darwin — A Fond Farewell to a Brilliant and Beautiful Theory,” published in the Claremont Review of Books. In that essay Gelernter explains that while he believes Darwin’s theory can account for small adaptive changes, it does not, in his view, satisfactorily explain the emergence of entirely new species.

Here’s the relevant passage from Gelernter’s essay as quoted in multiple sources:
“…there are many reasons to doubt whether he can answer the hard questions and explain the big picture — not the fine-tuning of existing species but the emergence of new ones. The origin of species is exactly what Darwin cannot explain.” (Science and Culture Today)

Giving Up Darwin
A fond farewell to a brilliant and beautiful theory by David Gelernter
Extract: Demolishing a Worldview
There’s no reason to doubt that Darwin successfully explained the small adjustments by which an organism adapts to local circumstances: changes to fur density or wing style or beak shape. Yet there are many reasons to doubt whether he can answer the hard questions and explain the big picture—not the fine-tuning of existing species but the emergence of new ones. The origin of species is exactly what Darwin cannot explain.
Origin Unknown of the following.
Yale University’s David Gelernter
Yale University’s David Gelernter—one of America’s most respected computer scientists—has become an unexpected but influential critic of Darwin’s evolutionary theory. His shift is not ideological but analytical: after decades of studying complex systems, probability, and biological discoveries, Gelernter concluded that Darwin’s model no longer fits the scientific evidence. As he famously stated, “The origin of species is exactly what Darwin cannot explain.”
Gelernter, known globally for pioneering early web technologies and advanced computational systems, now argues that the growing complexity uncovered by modern biology makes classical Darwinism scientifically untenable. His view is shaped not by theology or emotion but by the same logical and mathematical reasoning that built his career.
Why He No Longer Believes Darwinism Works
From an outside perspective, three major factors explain Gelernter’s rejection of Darwin’s theory:
1. The Mathematical Impossibility of Creating Functional Proteins by Chance
As a computer scientist, Gelernter is trained to evaluate probability and computational limits. When he examined protein formation—the foundation of all biological life—he was struck by the astronomical improbability of assembling even one functional protein through random mutation:
“The odds bury you. It can’t be done.”
To him, this isn’t religious; it’s mathematics. No known natural process can search such an impossibly vast space of possible amino acid combinations.
2. The Cambrian Explosion Contradicts Gradual Evolution
Gelernter sees the fossil record—especially the rapid appearance of fully formed body plans during the Cambrian period—as a direct challenge to Darwin’s slow, step-by-step model.
He observes that Darwin predicted transitional forms that simply do not appear:
Sudden complexity, he argues, is not consistent with unguided evolution.
3. Modern Molecular Biology Has Outgrown Darwin’s 19th-Century Theory
Advances in genetics, epigenetics, and molecular machinery reveal an intricacy far beyond what Darwin could have imagined. According to Gelernter, the deeper scientists dig into DNA, cell biology, and developmental programming, the harder it becomes to maintain the belief that random mutations can build entirely new species.
As he summarizes, referencing Darwin himself:
“Darwin would easily have understood that minor mutations are common but can’t create significant evolutionary change; major mutations are rare and fatal.”
This aligns with modern findings: mutations that alter body plans tend to destroy the organism, not improve it.
4. The Academic Pressure to Conform Strengthened His Doubts
From a third-person viewpoint, it’s clear Gelernter didn’t merely abandon Darwinism—he also became disillusioned with how rigidly the scientific community protects it. He describes an academic environment where dissent is punished, not debated:
“You take your life in your hands to challenge it intellectually. They will destroy you if you challenge it.”
This resistance, in his view, is not scientific but ideological.
He explains that the rejection of intelligent design is often emotional rather than rational:
“I am attacking their religion and I don’t blame them for being all head up, it is a big issue for them.”
Such statements reveal his core frustration: that Darwinism today is defended as dogma rather than evaluated as a theory.
5. His Shift Was Influenced by Serious Scholarship
Gelernter’s perspective changed after engaging deeply with works that challenge Darwinism. He credits Darwin’s Doubt and The Deniable Darwin with presenting scientific arguments he believes cannot be ignored.
Even though he doesn’t fully embrace intelligent design, he insists:
“It’s an absolutely serious scientific argument… the first and most obvious and intuitive one that comes to mind.”
From a neutral observer’s viewpoint, Gelernter represents a growing number of scientists who acknowledge the inadequacy of Darwin’s mechanism while seeking a more complete explanation—one that matches modern evidence.
6. He Believes Darwinism Has Become a Cultural Tradition, Not a Scientific Necessity
Gelernter notes that students absorb Darwinism from early education, often without critical evaluation:
“Young people are brought up as little Darwinists… The students in my class, they’re all Darwinists.”
From a third-person perspective, this highlights his broader criticism: the theory survives through cultural momentum rather than continued scientific validation.
A Final Perspective
Despite acknowledging Darwin’s success in explaining small-scale changes, Gelernter argues that the theory fails where it matters most:
“The origin of species is exactly what Darwin cannot explain.”
His conclusion is neither angry nor ideological—it is analytical. To him, the evidence no longer supports the theory.
He leaves biology with a challenge:
“How cleanly and quickly can the field get over Darwin, and move on?”
Whether the scientific community will accept that challenge remains to be seen.
