Historians tend to speak of the problem of the origin of species or the species question, as if it were a monolithic problem. In reality, the phrase refers to a, historically, surprisingly fluid and pluriform scientific issue. It has, in the course of the past five centuries, been used in no less than ten different ways or contexts. A clear taxonomy of these separate problems is useful or relevant in two ways. It certainly helps to disentangle confusions that have inevitably (...) emerged in the literature in its absence. It may, secondly, also help us to gain a more thorough understanding, or sharper view, of the history of evolutionary thought. A consequent problem-centric look at that history through the lens of various origin of species problems certainly yields intriguing results, including and particularly for our understanding of the genesis of the Wallace–Darwin theory of evolution through natural selection.

The Evolutionary Synthesis is often seen as a unification process in evolutionary biology, one which provided this research area with a solid common theoretical foundation. As such, neo-Darwinism is believed to constitute from this time onward a single, coherent, and unified movement offering research guidelines for investigations. While this may be true if evolutionary biology is solely understood as centred around evolutionary mechanisms, an entirely different picture emerges once other aspects of the founding neo-Darwinists’ views are taken into consideration, aspects (...) potentially relevant to the elaboration of an evolutionary worldview: the tree of life, the ontological distinctions of the main cosmic entities , the inherent properties of self-organizing matter, evolutionary ethics, and so on. Profound tensions and inconsistencies are immediately revealed in the neo-Darwinian movement once this broader perspective is adopted. This pluralism is such that it is possible to identify at least three distinct and quasi-incommensurable epistemological/metaphysical frameworks as providing a proper foundation for neo-Darwinism. The analysis of the views of Theodosius Dobzhansky, Bernhard Rensch, and Ernst Mayr will illustrate this untenable pluralism, one which requires us to conceive of the neo-Darwinian research agenda as being conducted in more than one research programme or research tradition at the same time.

WhenVestiges of the Natural History of Creation, the anonymous evolutionary work which caused such a furore in mid-Victorian England, was published towards the close of 1844, Richard Owen, by then well-entrenched as the ‘British Cuvier’, received a complementary copy and addressed a letter to the author. This letter and how it should be interpreted have recently become the subject of historical debate, and this paper is directed at resolving the controversy. The question of Owen's attitude to theVestigesargument is central to (...) the larger historical problem of the views of this leading British morphologist and palaeontologist on the contentious issue of the ‘secondary causes’ of species. Owen wrote so little directly on this subject prior to 1858, that the letter in question, together with his two letters of 1848 to the rationalist publisher John Chapman, and the controversial conclusion to hisOn the Nature of Limbs(1849), constitute the major evidence that Owen in this period subscribed to a naturalistic theory of organic change. On the basis of this evidence, historians of biology have generally concurred with Owen's biographer grandson that Owen had a ‘certain leaning towards the theories enunciated by Robert Chambers [the Vestiges' author]’, but that his ‘official’ anti-transmutationist stance of the 1840s did not permit full public expression of his own views. As Ruse most recently summed up this historical consensus: Owen in the 1840s was ‘moving down a path not completely dissimilar from that followed by Chambers’, and he ‘tried to have matters two ways, praisingVestigesto its author and condemning it to its critics’.

Wakley in 1846 called Grant “at once the most eloquent, the most accomplished, the most self-sacrificing, and the most unrewarded man in the profession.”128 I have shown some of the reasons why this was so, and I have suggested that his Lamarckism was one of a number of factors that served to alienate him from the conservative scientific community in the 1830's and 1840's. I have further shown the need for a fundamental rethinking of Grant's position in the history of (...) biology. There is little profit in seeing him as a precursor of Darwin. His importance lies as a teacher of philosophical anatomy and as the disseminator of Geoffroy's views in London. With the recent interest of historians in the emergence of a non-Paleyite approach to design in the 1830's (that is, an approach stemming from a unity of plan), a reassessment of Grant along these lines seems in order.Also, by understanding Grant's professional and transmutational threat, we can more fully appreciate the anti-Lamarckian ploys of leading scientists like Owen and Lyell. These scientific and social tactics reinforced the isolation Grant suffered as a result of his radical, materialistic, and antimonopolist views. Together with the laissez-faire arrangements at the joint-stock university, they led to his financial collapse — and to the decline of his scientific output that Darwin found so inexplicable. Beddoe described Grant as a disappointed man. “Alas!” wrote Wakley. “Who would be an English Cuvier?”129. (shrink)

In The life of Richard Owen by his grandson there is an inference to the effect that Owen had objected to his name being used to authorize various statements that Whewell was drafting in opposition to the Vestiges. The inference is drawn from letters that Whewell wrote to Owen on 13 and 15 February 1845. Corroboration of this would corne from a letter of Owen to Whewell, dated 14 February 1845, if extant. Among the Whewell papers at Trinity College, Cambridge, (...) there are several letters from Owen to Whewell, none of which bears that date. There is one, however, dated 14 February 1844 which, on doser inspection, turns out to be the missing link in their correspondance. The evidence for the misdating is not merely that the letter falls naturally into a later sequence. The conclusion is inescapable because Owen refers to an ‘opinion which I have always entertained, and still do strongly, on the subject of a refutation of “Vestiges”’. Since the first edition of Chambers's book did not appear until October 1844, the letter must belong to the following year. My object in this paper is to examine the implications of this letter for a reconstruction of Owen's attitude to that book which Adam Sedgwick could so detest for, among many things, its ‘gross views of physiology’.

The article sums up a number of points made by the author concerning the response to Darwinism in the late nineteenth and early twentieth centuries, and repeats the claim that a proper understanding of the theory's impact must take account of the extent to which what are now regarded as the key aspects of Darwin's thinking were evaded by his immediate followers. Potential challenges to this position are described and responded to.
