BOOK: Louis Agassiz’s Introduction to the Study of Natural History (Classic Texts in the Sciences)

A new series of books from Springer aims to publish important papers/lectures from the history of science, with supplemental information about the original author and their work. Of the five titles so far, one may be of interest to readers here: naturalist Louis Agassiz’s series of lectures given in Boston in the fall of 1846. It is edited and annotated by Agassiz biographer Christoph Irmscher, who published Louis Agassiz: Creator of American Science in 2013.

Publisher’s description This book features Louis Agassiz’s seminal lecture course in which the Swiss-American scientist, a self-styled “American Humboldt,” summarized the state of zoological knowledge in his time. Though Darwin’s theory of evolution would soon dismantle his idealist science, Agassiz’s lectures are nonetheless modern in their insistence on the social and cultural importance of the scientific enterprise. An extensive, well-illustrated introduction by Agassiz’s biographer, Christoph Irmscher, situates Agassiz’s lectures in the context of his life and nineteenth-century science, while also confronting the deeply problematic aspects of his legacy. Profusely annotated, this edition offers fascinating insights into the history of science and appeals to anyone with an interest in zoology and natural history.

Given the high cost of this volume ($150), it is surely a title intended for libraries, so do indeed request your library purchase it if it will be useful to you or history of science students at your university.

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

Curtis N. Johnson (author of Darwin’s Dice)

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.

“This Wonderful People”: Darwin, the Victorians, and the Greeks

Ageliki Lefkaditou

Abstract Studies of Victorian appropriations of the ancient world have allowed us to appreciate the pervasive influence of classical Greece on aesthetics and education, as well as religious, moral, and philosophical discourses. Celebrations of ancient Greek genius also prompted scientific interpretations of the past, present, and future of human society. For Charles Darwin (1809–1882), along with his correspondents Charles Lyell (1797–1875), Francis Galton (1822–1911), and William Rathbone Greg (1809–1881), the ancient Greeks were a race that had never been intellectually surpassed. Classical Athens therefore served as a precautionary tale of the multiple biological, sociopolitical, and geographical factors that may inhibit social progress. Their complementary, or even conflicting, understandings of the causes that prevented humankind from surpassing the ancient Greeks demonstrate subtle differences in their evolutionary perspectives. Against the Enlightenment faith in moral and intellectual improvement, Darwin’s thesis that evolutionary progress was “no invariable rule” was used to explain why empires of the past had declined, serving also as a guide for how Victorian Britain should address concerns such as migration, morality, and social order.

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.

BOOK: Buckets from an English Sea: 1832 and the Making of Charles Darwin

Here’s a new Darwin title that takes a very focused view on his life, just a single year…

Publisher’s description Darwin did not discover evolution. He didn’t trip over it on the way to somewhere else the way Columbus discovered the New World. Like the atom, planetary orbits, and so many other scientific constructs, evolution was invented in order to explain striking phenomena. And it has been most successful. A century and a half has not simply confirmed Darwin’s work, it has linked evolution to the mechanisms of life on the molecular scale. It is what life does. Where Darwin had drawn his theories from forest and field, we now set them in the coiling and uncoiling of twists of DNA, linking where they might, with a host of molecular bits and pieces scurrying about. Darwin, himself, however, has been a closed story. A century and a half of study of the man and his work, including close readings of his books, his notebooks and letters, and even the books he read, has led to a working appreciation of his genius. The ‘success’ of this account has, however, kept us from seeing several important issues: most notably, why did he pursue evolution in the first place? Buckets from an English Sea offers a new view of what inspired Darwin and provoked his work. Stunning events early in the voyage of the Beagle challenged his deeply held conviction that people are innately good. This study of 1832 highlights the resources available to the young Darwin as he worked to secure humanity’s innate goodness.
