Darwin’s two theories, 1844 and 1859

Derek Partridge

Abstract Darwin’s first two, relatively complete, explicit articulations of his theorizing on evolution were his Essay of 1844 and On the Origin of Species published in 1859. A comparative analysis concludes that they espoused radically different theories despite exhibiting a continuity of strategy, much common structure and the same key idea. Both were theories of evolution by means of natural selection. In 1844, organic adaptation was confined to occasional intervals initiated and controlled by de-stabilization events. The modified descendants rebalanced the particular “plant and animal forms … unsettled by some alteration in their circumstances.” But by 1859, organic adaptation occurred continuously, potentially modifying the descendants of all organisms. Even natural selection, the persistent core of Darwin’s theorizing, does not prove to be a significant basis for theory similarity. Consequently, Darwin’s Origin theory cannot reasonably be considered as a mature version of the Essay. It is not a modification based on adjustments, further justifications and the integration of a Principle of Divergence. The Origin announced a new “scientific paradigm” while the Essay did little more than seemingly misconfigure the operation of a novel mechanism to extend varieties beyond their accepted bounds, and into the realm of possible new species. Two other collections of Darwin’s theorizing are briefly considered: his extensive notes of the late 1830s and his contributions to the famous meeting of 1 July 1858. For very different reasons, neither constitutes a challenge to the basis for this comparative study. It is concluded that, in addition to the much-debated social pressures, an unacknowledged further reason why Darwin did not publish his theorizing until 1859, could have been down to his perceptive technical judgement: wisely, he held back from rushing to publish demonstrably flawed theorizing.

Comparing the respective transmutation mechanisms of Patrick Matthew, Charles Darwin and Alfred Wallace

Joachim L Dagg

Abstract A comparison of the evolutionary mechanisms of Patrick Matthew, Charles Darwin and Alfred Wallace highlights their differences. In Matthew’s scheme, catastrophes initiate periods of radiation and speciation until a fully stocked environment enters into stasis. Catastrophes first need to exterminate competing species before the survivors can radiate into free niches and diversify into new species. In Darwin’s early theory, conditions of life, such as those prevailing under domestication, first need to increase the variability of a species before natural selection can transform it. In Darwin’s mature theory, competition replaces conditions as the main drive behind evolutionary change, and sympatric speciation becomes possible. Wallace’s theory differs from both Matthew’s and Darwin’s. Interspecific competition is not a brake halting transmutation (as in Matthew’s theory) nor is intraspecific competition a sufficient drive for it. Although each theory integrated natural selection with variability, competition and changed conditions in distinct ways, each allowed for species transmutation somehow. The result was similar (transmutation), but the mechanisms yielding that result (the integration of natural selection with variability, competition and change in conditions) differed significantly.

BOOK: Reading the Rocks: How Victorian Geologists Discovered the Secret of Life

I am a few chapters into Reading the Rocks, a new book about the history of geology in the nineteenth century. I am enjoying Maddox’s writing style, and so far think this book would serve great as a good overview of the topic for those who don’t wish to delve into the much lengthier works of Martin Rudwick (that the author is much familiar with). I did spot two errors in the first chapter, which I hope is not indicative of pages to come – it’s a shame it wasn’t spotted!*

Publisher’s description The birth of geology was fostered initially by gentlemen whose wealth supported their interests, but in the nineteenth century, it was advanced by clergymen, academics, and women whose findings expanded the field. Reading the Rocks brings to life this eclectic cast of characters who brought passion, eccentricity, and towering intellect to the discovery of how Earth was formed. Geology opened a window on the planet’s ancient past. Contrary to the Book of Genesis, the rocks and fossils dug up showed that Earth was immeasurably old. Moreover, fossil evidence revealed progressive changes in life forms. It is no coincidence that Charles Darwin was a keen geologist. Acclaimed biographer and science writer Brenda Maddox’s story goes beyond William Smith, the father of English geology; Charles Lyell, the father of modern geology; and James Hutton, whose analysis of rock layers unveiled what is now called “deep time.” She also explores the lives of fossil hunter Mary Anning, the Reverend William Buckland, Darwin, and many others–their triumphs and disappointments, and the theological, philosophical, and scientific debates their findings provoked. Reading the Rocks illustrates in absorbing and revelatory details how this group of early geologists changed irrevocably our understanding of the world.

* In the first chapter (pp. 14-15) is the following passage: “… scientists estimate the age of the earth at roughly 4.6 billion years. The encompassing solar system is believed to have emerged around 13.7 billion years ago as a result of the ‘Big Bang’ – the collapse of a fragment of a giant molecular cloud.” The encompassing solar system would have been formed roughly the same time as did earth, 4.6 billion years ago. Our solar system did not form as a direct result of the Big Bang. Further, on p. 15, Maddox states incorrectly that life first emerged an estimated 540 million years ago, “first as single cells deep in the ocean, then as creatures with head, tails and segments.” It was the Cambrian explosion that occurred roughly 540 million years ago, not when life first evolved – the earliest fossils of life are from about 3.5 billion years ago.

Two new books centered on evolution and the human species

Here are two new books centered on evolution and the human species that readers here may be interested in:


Philip Lieberman, The Theory that Changed Everything: “On the Origin of Species” as a Work in Progress (New York: Columbia University Press, 2017), 232 pp.

Order through Powell’s City of BooksOrder through

Publisher’s description Few people have done as much to change how we view the world as Charles Darwin. Yet On the Origin of Species is more cited than read, and parts of it are even considered outdated. In some ways, it has been consigned to the nineteenth century. In The Theory That Changed Everything, the renowned cognitive scientist Philip Lieberman demonstrates that there is no better guide to the world’s living—and still evolving—things than Darwin and that the phenomena he observed are still being explored at the frontiers of science. In an exploration that ranges from Darwin’s transformative trip aboard the Beagle to Lieberman’s own sojourns in the remotest regions of the Himalayas, this book relates fresh, contemporary findings to the major concepts of Darwinian theory, which transcends natural selection. Drawing on his own research into the evolution of human linguistic and cognitive abilities, Lieberman explains the paths that adapted human anatomy to language. He demystifies the role of recently identified transcriptional and epigenetic factors encoded in DNA, explaining how nineteenth-century Swedish famines alternating with years of plenty caused survivors’ grandchildren to die many years short of their life expectancy. Lieberman is equally at home decoding supermarket shelves and climbing with the Sherpas as he discusses how natural selection explains features from lactose tolerance to ease of breathing at Himalayan altitudes. With conversational clarity and memorable examples, Lieberman relates the insights that led to groundbreaking discoveries in both Darwin’s time and our own while asking provocative questions about what Darwin would have made of controversial issues today, such as GMOs, endangered species, and the God question.

This book is reviewed, along with three other new titles about Darwin, in the Times Literary Supplement, and the author of said review discusses it for the TLS podcast.  And a so-so review from Publisher’s Weekly.


Kostas Kampourakis, Turning Points: How Critical Events Have Driven Human Evolution, Life, and Development (New York: Prometheus Books, February 2018), 384 pp. 

Order through Powell’s City of BooksOrder through

Publisher’s description Critical historical events–or “turning points”–have shaped evolution and continue to have a decisive effect on individual lives. This theme is explored and explained in this lucid, accessible book for lay readers. The author argues that, although evolution is the result of unpredictable events, these events have profound influences on subsequent developments. Life is thus a continuous interplay between unforeseeable events and their decisive consequences. As one example, the author cites the fusing of two chromosomes, which differentiated the human species from our closest animal relatives about 4 to 5 million years ago. This event was not predictable, but it had a profound effect on the evolution of our species thereafter. By the same token, certain unpredictable circumstances in the past enabled only Homo sapiens to survive to the present day, though we now know that other human-like species also once existed. The author contrasts such scientific concepts grounded in solid evidence with prevalent misconceptions about life: specifically, the religious notion that there is a plan and purpose behind life, the widespread perception that intelligent design governs the workings of nature, the persistent belief in destiny and fate, and the attribution of an overly deterministic role to genes. This excellent introduction for laypersons to core ideas in biology goes a long way toward dispelling such misconceptions and presents current scientific research in clearly understandable, jargon-free terms.

Again, this book is reviewed in Publisher’s Weekly.

A look at the Rhea County Courthouse in Dayton, TN, location of the 1925 Scopes “Monkey” Trial

My friend Catherine L. Cummins, a life science instructor at LSU Laboratory School in Baton Rouge, has shared some photos of her visit to the Rhea County Courthouse in Dayton, TN, location of the 1925 Scopes “Monkey” Trial. She was kind to let me share with my readers. Has anyone else ever visited this historic site?

The evolving spirit: morals and mutualism in Arabella Buckley’s evolutionary epic

Jordan Larsen

Abstract Contemporaries of Charles Darwin were divided on reconciling his theory of natural selection with religion and morality. Although Alfred Russel Wallace stands out as a spiritualist advocate of natural selection who rejected a natural origin of morality, the science popularizer and spiritualist Arabella Buckley (1840–1929) offers a more representative example of how theists, whether spiritualist or more orthodox in their religion, found reconciliation. Unlike Wallace, Buckley emphasized the lawful evolution of morality and of the soul, drawing from the theological tradition of traducianism. Significantly, Buckley argued for a mutualistic and deeply theistic interpretation of Darwinian evolution, particularly the evolution of morals, without sacrificing the uniformity of natural law. Though Buckley’s understanding of the evolutionary epic has been represented as emphasizing mutualism and spiritualist theology, here I demonstrate that her distinctive addition to the debate lies in her unifying theory of traducianism. In contrast to other authors, I argue that through Buckley we better understand Victorian spiritualism as more of a religion than an occult science. However, it was a conception of religion that, through her evolutionary traducianism, bridged science and spiritualism. This offers historians a more complex but satisfying image of the Victorian worldview after Darwin.

BOOK: God’s Word or Human Reason?: An Inside Perspective on Creationism

My way into learning about Darwin and evolution was through dinosaurs. Specifically, that 1993 movie where genetically-engineered dinosaurs run amok on a tropical island. I read book after book about paleontology following seeing that movie when I was 15, and then eventually started coming across books that offered a different view as to what those fossils in the ground meant (including What Is Creation Science? by Henry M. Morris and Gary E. Parker, gifted to me from a friend in my high school chemistry class). I’ve long followed the conflict between supporters of evolution (ya know, science!) and those who supplant their religious-based perspective on the fossil record: creationists of the young earth variety (you know, pseudoscience!). There are some good books out there that give an overview of why the fossil record supports an evolutionary interpretation (for example, Donald Prothero’s Evolution: What the Fossils Say and Why It Matters and two chapters in Richard Dawkins’ The Greatest Show on Earth: The Evidence for Evolution). Where this new book differs is that the evidence is shown in favor of the evolutionary perspective by five former young earth creationists. Chapters cover creationist arguments in the topics of the fossil record in relation to a worldwide flood, the age of the Earth through radiometric dating, the evolution of birds from dinosaurs, human anatomy, and perspectives on reconciling an old earth and evolution with an acceptance of the Bible. The book also features wonderful dinosaur art from Emily Willoughby.

Publisher’s description God gave humans the ability to reason, but the Bible commands that we have faith in Him. According to Answers in Genesis, the largest and most influential creationist organization in the United States, the conclusions of human reason must be rejected if they contradict our understanding of the Bible. What are the implications of this worldview, and is it the best one for a Christian to live by?

In God’s Word or Human Reason?, five former young-Earth creationists explore the topics of science and Biblical exegesis with the goal of showing that the scientific method does more to glorify God than to denigrate Him. Instead of providing a broad-level overview of the evidence for evolution and an old Earth, this book takes a new approach that considers the detailed expanse of creationist technical literature. The six main chapters provide an in­ depth examination of these arguments in a few key areas, including stratigraphy, radiometric dating, the origins of birds and of humans, and the meaning of the book of Genesis.

Although all five authors once were young-Earth creationists, today they represent a diversity of beliefs: two atheists, two Christians, and one deist. Each has included a personal account of their experiences growing up or participating in the creationist community, as well as the factors that played into their eventually leaving. As an interfaith project, God’s Word or Human Reason? represents the common ground that people of many religious affiliations can find in their appreciation of reason as a means to understand the world.

Censoring Huxley and Wilberforce: A new source for the meeting that the Athenaeum ‘wisely softened down’

Richard England

Abstract In mid July 1860, the Athenaeum published a summary of the discussions about Charles Darwin’s theory that took place at the British Association meeting in Oxford. Its account omitted the famous exchange between Samuel Wilberforce, Bishop of Oxford, and Thomas Huxley, the rising man of science. A fuller report of the meeting was published a week later in a local weekly, the Oxford Chronicle, but this has gone unnoticed by historians. The Oxford Chronicle supplies a new version of Wilberforce’s question to Huxley, with more material about religious objections to human evolution and the proper role of authority in popular scientific discussions. Excerpts from the Athenaeum and Oxford Chronicle accounts show that they likely had a common ancestor, and other sources corroborate details given only in the Oxford Chronicle. This discovery reveals that the Athenaeum narrative—until now the longest and best known—was censored to remove material that was considered objectionable. The Oxford Chronicle gives us a fuller story of what was said and how the audience reacted to the encounter between Huxley and Wilberforce.
