Charles Darwin, Richard Owen, and Natural Selection: A Question of Priority

Curtis N. Johnson

Abstract No single author presented Darwin with a more difficult question about his priority in discovering natural selection than the British comparative anatomist and paleontologist Richard Owen. Owen was arguably the most influential biologist in Great Britain in Darwin’s time. Darwin wanted his approbation for what he believed to be his own theory of natural selection. Unfortunately for Darwin, when Owen first commented in publication about Darwin’s theory of descent he was openly hostile (Edinb. Rev. vol. 111, Article VIII, 1860, pp. 487–533, anonymous). Darwin was taken off-guard. In private meetings and correspondence prior to 1860 Owen had been nothing but polite and friendly, even helping Darwin in cataloguing and analyzing Darwin’s zoological specimens from the Beagle voyage. Every early indication predicted a life-long friendship and collaboration. But that was not to be. Owen followed his slashing review with a mounting campaign in the 1860s to denounce and discredit both Darwin and his small but ascendant circle of friends and supporters. But that was not enough for Owen. Starting in 1866, perhaps by now realizing Darwin had landed the big fish, Owen launched a new campaign, to claim the discovery of “Darwin’s theory” for himself. Darwin naturally fought back, mainly in the “Historical Sketch” that he prefaced to Origin starting in 1861. But when we peel back the layers of personal animus and escalating vituperation we discover in fact their quarrel was generated more by mutual misunderstanding than scientific disagreement. The battle ended only when Darwin finally penetrated to the crux of the matter and put an end to the rivalry in 1872, in the final version of the Sketch.


Darwin, evolution & science books for holiday gift giving

‘Tis the season for holiday gift giving (to others or to yourself, no shame there), so I thought I’d share about some recent books about evolution and related topics that might strike in you a desire to spread the good news (of science!).



Rebecca Stefoff and Teagan White (illustrator), Charles Darwin’s On the Origin of Species: Young Readers Edition (New York: Atheneum Books for Young Readers, 2018, 176. pp.) ~ As she has done for other books (Howard Zinn’s A People’s History of the United States, Jared Diamond’s The Third Chimpanzee, and Charles C. Mann’s 1493), Stefoff has taken an important book and adapted it for a younger audience, using more accessible language and including copious illustrations and photographs, and while remaining true to Darwin’s chapter structure, has provided updated information on topics that have, well, evolved since Darwin’s time. If On the Origin of Species continues to be a book that everyone has an opinion about yet have never actually read (it can be a challenging read), perhaps they can start with this handsome large format edition. It surely deserves a place on the shelves of middle and high school libraries. Order Charles Darwin’s On the Origin of Species: Young Readers Edition: Amazon, Powell’s, Barnes & Noble, Indiebound.

From the publisher: “The Galápagos Islands are home to an amazing variety of iconic creatures, from Giant Tortoises, Galápagos Sea Lions, Galápagos Penguins, and Ghost Crabs to Darwin’s finches, the Blue-footed Booby, and Hummingbird Moths. But how precisely do these animals manage to survive on―and in the waters around―their desert-like volcanic islands, where fresh water is always scarce, food is often hard to come by, and finding a good mate is a challenge because animal populations are so small? In this stunning large-format book, Galápagos experts Walter Perez and Michael Weisberg present an unprecedented photographic account of the remarkable survival behaviors of these beautiful and unique animals. With more than 200 detailed, close-up photographs, the book captures Galápagos animals in action as they feed, play, fight, court, mate, build nests, give birth, raise their young, and cooperate and clash with other species.” Order Galápagos: Life in Motion: Amazon, Powell’s, Barnes & Noble, Indiebound.

On the bookshelf: Evolution, anthropology, geology, philosophy of paleontology, and early 20th century activism for birds


The following titles are some of the books I have been reading or have recently obtained that readers here are likely to find of interest. Ordering links follow the descriptions of each book, but I recommend also checking your local bookstore or library!

Efram, Sera-Shriar (ed.), Historicizing Humans: Deep Time, Evolution, and Race in Nineteenth-Century British Sciences (University of Pittsburgh Press, 2018, 320 pp.) ~ The publiher’s description reads: “A number of important developments and discoveries across the British Empire’s imperial landscape during the nineteenth century invited new questions about human ancestry. The rise of secularism and scientific naturalism; new evidence, such as skeletal and archaeological remains; and European encounters with different people all over the world challenged the existing harmony between science and religion and threatened traditional biblical ideas about special creation and the timeline of human history. Advances in print culture and voyages of exploration also provided researchers with a wealth of material that contributed to their investigations into humanity’s past. Historicizing Humans takes a critical approach to nineteenth-century human history, as the contributors consider how these histories were shaped by the colonial world, and for various scientific, religious, and sociopolitical purposes. This volume highlights the underlying questions and shared assumptions that emerged as various human developmental theories competed for dominance throughout the British Empire.” Readers interested in Darwin specifically will want to check out chapter 6 – Gregory Radick on “How and Why Darwin Got Emotional about Race.” Radick delves into Darwin’s writing in The Expression of the Emotions in Man and Animals (1872) as a means to understand Darwin’s thoughts on human evolution and suggests that Expression provides more evidence in Darwin’s mind of man’s animal ancestry than what he offered in On the Origin of Species (1859) or The Descent of Man (1871). Order Historicizing Humans: Amazon, Powell’s, Barnes & Noble, Indiebound.

Kieran D. O’Hara, A Brief History of Geology (Cambridge University Press, 2018, 274 pp.) ~ “Geology as a science has a fascinating and controversial history. Kieran D. O’Hara’s book provides a brief and accessible account of the major events in the history of geology over the last two hundred years, from early theories of Earth structure during the Reformation, through major controversies over the age of the Earth during the Industrial Revolution, to the more recent twentieth-century development of plate tectonic theory, and on to current ideas concerning the Anthropocene. Most chapters include a short ‘text box’ providing more technical and detailed elaborations on selected topics. The book also includes a history of the geology of the Moon, a topic not normally included in books on the history of geology. The book will appeal to students of Earth science, researchers in geology who wish to learn more about the history of their subject, and general readers interested in the history of science.” Order A Brief History of GeologyAmazon, Powell’s, Barnes & Noble, Indiebound.

Peter R. Grant and B. Rosemary Grant, 40 Years of Evolution: Darwin’s Finches on Daphne Major Island (Princeton University Press, 2014, 432 pp.) ~ One of the very first books I read about evolution when the topic grabbed me as a teenager was The Beak of the Finch by Jonathan Weiner (1995), which told the story of the Grants’ lengthy study of finches on the Galapagos islands. Jump two decades later and their research in the field continues, as they describe in this newer book. From the publisher: “Renowned evolutionary biologists Peter and Rosemary Grant have produced landmark studies of the Galápagos finches first made famous by Charles Darwin. In How and Why Species Multiply [2008], they offered a complete evolutionary history of Darwin’s finches since their origin almost three million years ago. Now, in their richly illustrated new book, 40 Years of Evolution, the authors turn their attention to events taking place on a contemporary scale. By continuously tracking finch populations over a period of four decades, they uncover the causes and consequences of significant events leading to evolutionary changes in species. The authors used a vast and unparalleled range of ecological, behavioral, and genetic data–including song recordings, DNA analyses, and feeding and breeding behavior–to measure changes in finch populations on the small island of Daphne Major in the Galápagos archipelago. They find that natural selection happens repeatedly, that finches hybridize and exchange genes rarely, and that they compete for scarce food in times of drought, with the remarkable result that the finch populations today differ significantly in average beak size and shape from those of forty years ago. The authors’ most spectacular discovery is the initiation and establishment of a new lineage that now behaves as a new species, differing from others in size, song, and other characteristics. The authors emphasize the immeasurable value of continuous long-term studies of natural populations and of critical opportunities for detecting and understanding rare but significant events. By following the fates of finches for several generations, 40 Years of Evolution offers unparalleled insights into ecological and evolutionary changes in natural environments.” Order 40 Years of EvolutionAmazon, Powell’s, Barnes & Noble, Indiebound.

Tessa Boase, Mrs Pankhurst’s Purple Feather: Fashion, Fury and Feminism – Women’s Fight for Change (Aurum Press, 2018, 336 pp.) ~ Women’s suffrage in Britain began in 1918, when certain woman over the age of 30 were granted the right to vote, but the effort to reach such a point had begun decades earlier. Social historian Tessa Boase tells the story of how the women’s suffrage movement was intertwined with the movement to protect British birds. The publisher’s description: “When Mrs Pankhurst stormed the House of Commons with her crack squad of militant suffragettes in 1908, she wore on her hat a voluptuous purple feather. This is the intriguing story behind that feather. Twelve years before the suffragette movement began dominating headlines, a very different women’s campaign captured the public imagination. Its aim was radical: to stamp out the fashion for feathers in hats. Leading the fight was a character just as heroic as Emmeline Pankhurst, but with opposite beliefs. Her name was Etta Lemon, and she was anti-fashion, anti-feminist – and anti-suffrage. Mrs Lemon has been forgotten by history, but her mighty society lives on. Few, today, are aware that Britain’s biggest conservation charity, the RSPB, was born through the determined efforts of a handful of women, led by the indomitable Mrs Lemon. While the suffragettes were slashing paintings and smashing shop windows, Etta Lemon and her local secretaries were challenging ‘murderous millinery’ all the way up to Parliament. This gripping narrative explores two singular heroines – one lionised, the other forgotten – and their rival, overlapping campaigns. Moving from the feather workers’ slums to the highest courtly circles, from the first female political rally to the first forcible feeding, Mrs Pankhurst’s Purple Feather is a unique journey through a society in transformation. This is a highly original story of women stepping into the public sphere, agitating for change – and finally finding a voice.” Order Mrs Pankhurst’s Purple FeatherAmazon, Powell’s, Barnes & Noble, Indiebound.

Peter Ward, Lamarck’s Revenge: How Epigenetics Is Revolutionizing Our Understanding of Evolution’s Past and Present (Bloomsbury Publishing, 2018, 288 pp.) ~ “In the 1700s, Jean-Baptiste Lamarck first described epigenetics to explain the inheritance of acquired characteristics; however, his theory was supplanted in the 1800s by Darwin’s theory of evolution by natural selection through heritable genetic mutations. But natural selection could not adequately explain how rapidly species re-diversified and repopulated after mass extinctions. Now advances in the study of DNA and RNA have resurrected epigenetics, which can create radical physical and physiological changes in subsequent generations by the simple addition of a single small molecule, thus passing along a propensity for molecules to attach in the same places in the next generation! Epigenetics is a complex process, but paleontologist and astrobiologist Peter Ward breaks it down for general readers, using the epigenetic paradigm to reexamine how the history of our species–from deep time to the outbreak of the Black Plague and into the present–has left its mark on our physiology, behavior, and intelligence. Most alarming are chapters about epigenetic changes we are undergoing now triggered by toxins, environmental pollutants, famine, poor nutrition, and overexposure to violence. Lamarck’s Revenge is an eye-opening and controversial exploration of how traits are inherited, and how outside influences drive what we pass along to our progeny.” Order Lamarck’s RevengeAmazon, Powell’s, Barnes & Noble, Indiebound.

Adrian Currie, Rock, Bone, and Ruin: An Optimist’s Guide to the Historical Sciences (MIT Press, 2018, 376 pp.) ~ I’ve read lots of books about dinosaurs and paleontology over the years, but this one suggests to not necessarily take everything a paleontologist says for granted. From the publisher: “The ‘historical sciences’—geology, paleontology, and archaeology—have made extraordinary progress in advancing our understanding of the deep past. How has this been possible, given that the evidence they have to work with offers mere traces of the past? In Rock, Bone, and Ruin, Adrian Currie explains that these scientists are ‘methodological omnivores,’ with a variety of strategies and techniques at their disposal, and that this gives us every reason to be optimistic about their capacity to uncover truths about prehistory. Creative and opportunistic paleontologists, for example, discovered and described a new species of prehistoric duck-billed platypus from a single fossilized tooth. Examining the complex reasoning processes of historical science, Currie also considers philosophical and scientific reflection on the relationship between past and present, the nature of evidence, contingency, and scientific progress. Currie draws on varied examples from across the historical sciences, from Mayan ritual sacrifice to giant Mesozoic fleas to Mars’s mysterious watery past, to develop an account of the nature of, and resources available to, historical science. He presents two major case studies: the emerging explanation of sauropod size, and the ‘snowball earth’ hypothesis that accounts for signs of glaciation in Neoproterozoic tropics. He develops the Ripple Model of Evidence to analyze ‘unlucky circumstances’ in scientific investigation; examines and refutes arguments for pessimism about the capacity of the historical sciences, defending the role of analogy and arguing that simulations have an experiment-like function. Currie argues for a creative, open-ended approach, ’empirically grounded’ speculation.” Order Rock, Bone, and Ruin: AmazonPowell’s, Barnes & Noble, Indiebound.

ARTICLE: Darwin among the Philosophers: Hull and Ruse on Darwin, Herschel, and Whewell

A new Darwin article in the HOPOS: The Journal of the International Society for the
History of Philosophy of Science:

Darwin among the Philosophers: Hull and Ruse on Darwin, Herschel, and Whewell

Phillip Honenberger

Abstract In a series of articles and books published in the 1970s, David Hull (1935–2010) and Michael Ruse (1940–) proposed interpretations of the relation between nineteenth-century British philosophy of science, on the one hand, and the views and methods of Charles Darwin, on the other, that were incompatible or at least in strong interpretive tension with one another. According to Hull, John Herschel’s and William Whewell’s philosophies of science were logically incompatible with Darwin’s revolutionary theory. According to Ruse, however, Darwin discovered and developed his theory through direct adherence to those philosophies. Here, I reconstruct Hull’s and Ruse’s interpretations of the Herschel-Whewell-Darwin relationship and then, drawing on Hull’s and Ruse’s published record and archival correspondence in the years 1968–76—particularly regarding reduction, laws, and species—I offer an explanation for their differences, namely, their different orientations to logical empiricism.


BOOK: Unnatural Selection by Katrina van Grouw

This summer, I – and a theater full of lovers of science – were treated to a talk from natural history illustrator, scientist, and author Katrina van Grow. At one of Portland’s Science on Tap evenings, the author of the popular Unfeathered Bird (Princeton University Press, 2013) shared all about her new book Unnatural Selection (also from Princeton University Press), and she did so enthusiastically. Illustrating and discussing animal skeletons is obviously a passion of hers, and it showed wonderfully in her presentation. I was delighted to buy a copy of Unnatural Selection from her. For others, this would make a great gift for the Darwin aficionado in your life!

Unnatural Selection (1)

The subject of Unnatural Selection, opposite that of Darwin’s “natural selection,” is the human-initiated selective breeding of domestic animals: the dogs, pigeons, chickens and geese, and livestock that grace the pages of this beautiful, large-format book. The publisher’s description:

Unnatural Selection is a stunningly illustrated book about selective breeding–the ongoing transformation of animals at the hand of man. More important, it’s a book about selective breeding on a far, far grander scale—a scale that encompasses all life on Earth. We’d call it evolution. A unique fusion of art, science, and history, this book celebrates the 150th anniversary of Charles Darwin’s monumental work The Variation of Animals and Plants under Domestication, and is intended as a tribute to what Darwin might have achieved had he possessed that elusive missing piece to the evolutionary puzzle—the knowledge of how individual traits are passed from one generation to the next. With the benefit of a century and a half of hindsight, Katrina van Grouw explains evolution by building on the analogy that Darwin himself used—comparing the selective breeding process with natural selection in the wild, and, like Darwin, featuring a multitude of fascinating examples. This is more than just a book about pets and livestock, however. The revelation of Unnatural Selection is that identical traits can occur in all animals, wild and domesticated, and both are governed by the same evolutionary principles. As van Grouw shows, animals are plastic things, constantly changing. In wild animals the changes are usually too slow to see—species appear to stay the same. When it comes to domesticated animals, however, change happens fast, making them the perfect model of evolution in action. Suitable for the lay reader and student, as well as the more seasoned biologist, and featuring more than four hundred breathtaking illustrations of living animals, skeletons, and historical specimens, Unnatural Selection will be enjoyed by anyone with an interest in natural history and the history of evolutionary thinking.

I’ve poured over the fantastic illustrations and look forward to diving into the text!

ARTICLE: Diagramming Evolution: The Case of Darwin’s Trees

A new article in the journal Endeavour:

Diagramming Evolution: The Case of Darwin’s Trees

Greg Priest

Abstract From his earliest student days through the writing of his last book, Charles Darwin drew diagrams. In developing his evolutionary ideas, his preferred form of diagram was the tree. An examination of several of Darwin’s trees—from sketches in a private notebook from the late 1830s through the diagram published in the Origin—opens a window onto the role of diagramming in Darwin’s scientific practice. In his diagrams, Darwin simultaneously represented both observable patterns in nature and conjectural narratives of evolutionary history. He then brought these natural patterns and narratives into dialogue, allowing him to explore whether the narratives could explain the patterns. But Darwin’s diagrams did not reveal their meaning directly to passive readers; they required readers to engage dynamically with them in order to understand the connections they disclosed between patterns and narratives. Moreover, the narratives Darwin depicted in his diagrams did not represent past sequences of events that he claimed had actually occurred; the narratives were conjectural, schematic, and probabilistic. Instead of depicting actual histories in all their particularity, Darwin depicted narratives in his diagrams in order to make general claims about how nature works. The conjunction of these features of Darwin’s diagrams is central to how they do their epistemic work.
