In the wake of the paleobiological revolution of the 1970s and 1980s, paleontologists continue to investigate far-reaching questions about how evolution works. Many of those questions have a philosophical dimension. How is macroevolution related to evolutionary changes within populations? Is evolutionary history contingent? How much can we know about the causes of evolutionary trends? How do paleontologists read the patterns in the fossil record to learn about the underlying evolutionary processes? Derek Turner explores these and other questions, introducing the reader (...) to exciting recent work in the philosophy of paleontology and to theoretical issues including punctuated equilibria and species selection. He also critically examines some of the major accomplishments and arguments of paleontologists of the last 40 years. (shrink)

In this paper, I discuss several temporal aspects of paleontology from a philosophical perspective. I begin by presenting the general problem of “taming” deep time to make it comprehensible at a human scale, starting with the traditional geologic time scale: an event-based, relative time scale consisting of a hierarchy of chronological units. Not only does the relative timescale provide a basis for reconstructing many of the general features of the history of life, but it is also consonant with the (...) cognitive processes humans use to think about time. Absolute dating of rocks, fossils, and evolutionary events (such as branching events on the tree of life) can be accomplished through the use of radiometric dating, chronological signals extractable from fossil growth patterns, and the “molecular clock.” Sometimes these different methods of absolute dating, which start from largely independent assumptions and evidentiary bases, converge in their temporal estimates, resulting in a consilience of inductions. At other times they fail to agree, either because fossils and molecules are giving temporal information about different aspects of nature and should not be expected to agree, or because of flawed assumptions that give rise to an inaccurate estimate. I argue that in general, despite the fact that it can be difficult to integrate disparate kinds of evidence, the principle of total evidence should be applied to the dating of evolutionary events. As a historical science, paleontology studies past events we cannot observe directly. This raises questions of epistemic access, meaning that due to the fragmentary nature of the fossil record we may find ourselves without access to the relevant traces to adjudicate between rival hypotheses about the past. The problems and prospects of epistemic access are explored through a case study of the reconstruction of the colors of dinosaurs. The paper closes with a reflection on the Darwin- Lyell metaphor of the fossil record as a highly fragmentary history book, and a call for a reconsideration of the book metaphor in favor of a systems view of the geologic and fossil records.

This paper examines the subversive role of statistics paleontology at the end of the 19th and the beginning of the 20th centuries. In particular, I will focus on German paleontology and its relationship with statistics. I argue that in paleontology, the quantitative method was questioned and strongly limited by the first decade of the 20th century because, as its opponents noted, when the fossil record is treated statistically, it was found to generate results openly in conflict with (...) the Darwinian theory of evolution. Essentially, statistics questions the gradual mode of evolution and the role of natural selection. The main objections to statistics were addressed during the meetings at the Kaiserlich-Königliche Geologische Reichsanstalt in Vienna in the 1880s. After having introduced the statistical treatment of the fossil record, I will use the works of Charles Léo Lesquereux, Joachim Barrande, and Henry Shaler Williams to compare the objections raised in Vienna with how the statistical treatment of the data worked in practice. Furthermore, I will discuss the criticisms of Melchior Neumayr, one of the leading German opponents of statistical paleontology, to show why, and to what extent, statistics were questioned in Vienna. The final part of this paper considers what paleontologists can derive from a statistical notion of data: the necessity of opening a discussion about the completeness and nature of the paleontological data. The Vienna discussion about which method paleontologists should follow offers an interesting case study in order to understand the epistemic tensions within paleontology surrounding Darwin’s theory as well as the variety of non-Darwinian alternatives that emerged from the statistical treatment of the fossil record at the end of the 19th century.

The role of paleontology in evolutionary biology between the publication of The Origin of Species in 1859 and the Evolutionary Synthesis of the 1940s is frequently described as mostly misguided failure. However, a significant number of American and British PDPS invertebrate paleontologists of this period did devote considerable attention to evolution, and their evolutionary theories and conclusions were a good deal more diverse and nuanced than previous histories have suggested. This paper brings into focus a number of important but (...) underrecognized aspects of the history of paleontology within the history of biology, including that PDPS paleontologists were not all as theoretically backward as they have been portrayed; that the post-Synthesis narrative of the history of evolution should be continually reevaluated, in part to decouple historical understanding from the agendas of authors who have used history to advance particular views of evolution; and that there is a much richer story to be told about the history of evolutionary biology in both the pre- and post-Synthesis eras.

ABSTRACT While a great deal of scholarly attention has been given to the publication of serialized novels in early Victorian Britain, there has been hardly any consideration of the no less widespread practice of issuing scientific works in parts and numbers. What scholarship there has been has insisted that scientific part-works operated on entirely different principles from the strategies for maintaining readerly interest that were being developed by serial novelists like Charles Dickens. Deploying the methods of book history, this essay (...) examines the reporting of Richard Owen's celebrated paleontological reconstructions from the 1830s and 1840s in the serialized formats of the Proceedings of the Zoological Society, his own History of British Fossil Mammals, and, in particular, the Penny Cyclopaedia. It argues that Owen, along with his close friend William John Broderip, clearly recognized the affective possibilities of the serial format and that they exploited the Penny Cyclopaedia's sequential mode of publication to evoke suspense and expectation in their anonymous but collaboratively authored accounts of Owen's paleontological researches.

This paper examines the way in which paleontologists used “popular books” to call for a broader “expanded synthesis” of evolutionary biology. Beginning in the 1970s, a group of influential paleontologists, including Stephen Jay Gould, Niles Eldredge, David Raup, Steven Stanley, and others, aggressively promoted a new theoretical, evolutionary approach to the fossil record as an important revision of the existing synthetic view of Darwinism. This work had a transformative effect within the discipline of paleontology. However, by the 1980s, paleontologists (...) began making their case to a wider audience, both within evolutionary biology, and to the general public. Many of their books—for example, Eldredge’s provocatively-titled Unfinished Synthesis—explicitly argued that the received synthetic view of Darwinian evolution was incomplete, and that paleontological contributions such as punctuated equilibria, the hierarchical model of macroevolution, and the study of mass extinction dynamics offered a substantial corrective to evolutionary theory. This paper argues that books—far from being “mere popularizations” of scientific ideas—played an important role in disciplinary debates surrounding evolutionary theory during the 1980s, and in particular that paleontologists like Gould and Eldredge self-consciously adopted the book format because of the importance of that genre in the history of evolutionary biology.

In lieu of an abstract, here is a brief excerpt of the content:A Far-Future Paleontology: The Baffling Case of Brunaspis enigmaticaAnne-Sophie Milon (bio) and Jan Zalasiewicz (bio)Paleontologists, for more than two centuries, have studied and debated the petrified remains of plants and animals that have evolved over the past three billion years on Earth. They have argued over the grand concepts that they reveal, such as biological evolution and climate change, and also the many specific questions thrown up by (...) these relics: was such-and-such a shell, a mollusk, or an arthropod? Did this fossil fish live high up in the water, among the plankton, or grub in the mud on the sea floor?These studies have for many paleontologists been a blessedly human-free zone, detached from the busy realities of our everyday lives. The science of paleontology, though, is simply one obscure part of a burgeoning and rapidly evolving technosphere that underpins our lives, and that is now evolving millions of new kinds of fossils—technofossils—far more rapidly than ever happened in biological evolution. Many of these objects will, quite certainly, become part of Earth’s future fossil record.If such an endeavor as paleontology were ever to arise again, in a distant post-human future, how would its practitioners deal with these bizarre relics?We provide a preview, on the following pages, of just one such enigma, and how it may be resolved (or not) by our puzzled disciplinary descendants.

The distinction between idiographic science, which aims to reconstruct sequences of particular events, and nomothetic science, which aims to discover laws and regularities, is crucial for understanding the paleobiological revolution of the 1970s and 1980s. Stephen Jay Gould at times seemed conflicted about whether to say (a) that idiographic science is fine as it is or (b) that paleontology would have more credibility if it were more nomothetic. Ironically, one of the lasting results of the paleobiological revolution was a (...) new way of doing historical science that defies categorization as idiographic or nomothetic. Yet the tension between (a) and (b) persists in some recent work in the philosophy of science, with Carol Cleland defending a version of (a) and Dan McShea and Robert Brandon defending a version of (b). In placing Cleland's work into conversation with that of McShea and Brandon, this paper defends a third (c) synthetic approach that emphasizes the blending of idiographic and nomothetic work.

New technologies can upset scientific workplaces’ established practices and social order. Scientists may therefore prefer preserving skilled manual work and the social status quo to revolutionary technological change. For example, digital imaging of rock-encased fossils is a valuable way for scientists to “see” a specimen without traditional rock removal. However, interviews in vertebrate paleontology laboratories reveal workers’ skepticism toward computed tomography imaging. Scientists criticize replacing physical fossils with digital images because, they say, images are more subjective than the “real (...) thing.” I argue that these scientists are also implicitly supporting rock-removal technicians, who are skilled and trusted experts whose work would be made obsolete by widespread implementation of CT scanning. Scientists’ view of CT as a sometimes useful tool rather than a universal new approach to accessing fossils preserves the laboratory community’s social structure. Specifically, by privileging “real” specimens and trusted specimen-processing technicians over images and imaging experts, scientists preserve the lab community’s division of labor and skill, hierarchy between scientists and technicians, and these groups’ identity and mutual trust.

At the turn of the last century, paleontologists wagered that they could find the missing link between lobe-finned fish and early terrestrial vertebrates. Given how these evolutionary relatives are distributed in the fossil record, Daeschler et al. predicted that some transitional form awaited discovery in late Devonian outcrops of the Canadian Arctic. It was there that they won their bet: the team soon found Tiktaalik roseae, a “fishopod” with a mix of aquatic and terrestrial traits. Tiktaalik’s discovery now stands as (...) paleontologists’ textbook case of scientific reasoning done right. (shrink)

The practice of paleontology has an aesthetic as well as an epistemic dimension. Paleontology has distinctively aesthetic aims, such as cultivating sense of place and developing a better aesthetic appreciation of fossils. Scientific cognitivists in environmental aesthetics argue that scientific knowledge deepens and enhances our appreciation of nature. Drawing on that tradition, this Element argues that knowledge of something's history makes a difference to how we engage with it aesthetically. This means that investigation of the deep past can (...) contribute to aesthetic aims. Aesthetic engagement with fossils and landscapes is also crucial to explaining paleontology's epistemic successes. (shrink)

Carman argues, in ‘The electrons of the dinosaurs and the center of the Earth’, that we may have more reason to be realists about dinosaurs than about electrons, because there are plenty of observable analogues for dinosaurs but not for electrons. These observable analogues severely restrict the range of plausible ontologies, thus reducing the threat of underdetermination. In response to this argument, I show that the observable analogues for ancient organisms are a mixed epistemic blessing at best, and I discuss (...) some cases from the history of paleontology in which the observable analogues—ducks, shrimp, and lizards—have led scientists into persisting error. I also give reasons for thinking that underdetermination will be just as serious a problem in historical as in experimental science. I conclude that Carman has not succeeded in showing that dinosaurs ‘come off better’ than electrons.Keywords: Paleontology; Pessimistic induction; Realism; Unobservables. (shrink)

In the received view of the history of the Modern Evolutionary Synthesis, paleontology was given a prominent role in evolutionary biology thanks to the significant influence of paleontologist George Gaylord Simpson on both the institutional and conceptual development of the Synthesis. Simpson's 1944 Tempo and Mode in Evolution is considered a classic of Synthesis-era biology, and Simpson often remarked on the influence of other major Synthesis figures – such as Ernst Mayr and Theodosius Dobzhansky – on his developing thought. (...) Why, then, did paleontologists of the 1970s and 1980s – Stephen Jay Gould, Niles Eldredge, David M. Raup, Steven Stanley, and others – so frequently complain that paleontology remained marginalized within evolutionary biology? This essay considers three linked questions: first, were paleontologists genuinely welcomed into the Synthetic project during its initial stages? Second, was the initial promise of the role for paleontology realized during the decades between 1950 and 1980, when the Synthesis supposedly "hardened" to an "orthodoxy"? And third, did the period of organized dissent and opposition to this orthodoxy by paleontologists during the 1970s and 1980s bring about a long-delayed completion to the Modern Synthesis, or rather does it highlight the wider failure of any such unified Darwinian evolutionary consensus?

Exploring history pertinent to evolutionary developmental biology (hereafter, Evo-devo) is an exciting prospect given its current status as a cutting-edge field of research. The first and obvious question concerns where to begin searching for materials and sources. Since this new discipline adopts a moniker that intentionally juxtaposes ‘evolution’ and development’, individuals, disciplines, and institutional contexts relevant to the history of evolutionary studies and investigations of ontogeny prompt themselves. Each of these topics has received attention from historians and thus there is (...) both primary and secondary material from which to draw. For example, many historians have documented the historical trajectories of genetics and embryology, their split, and various relations (or lack thereof), especially in the first three decades of the 20th century.

Over the first decades of the twentieth century, the fragmentary remains of a huge prehistoric ungulate were unearthed in scientific expeditions in India, Turkestan and Mongolia. Following channels of formal and informal empire, these were transported to collections in Britain, Russia and the United States. While striking and of immense size, the bones proved extremely difficult to interpret. Alternately naming the creature Paraceratherium, Baluchitherium and Indricotherium, paleontologists Clive Forster-Cooper, Alexei Borissiak and Henry Fairfield Osborn struggled over the reconstruction of this (...) gigantic fossil mammal. However, despite these problems, shared work on the creature served as a focus for collaboration and exchange rather than rivalry between these three scientific communities. Not only did the initial interpretation and analysis depend on pre-existing connections between British and American paleontological institutions, but the need for comparative material, recognition and contacts brought British and American scholars into communication and exchange with their counterparts in the Soviet Union. This article examines these processes. It first uses these excavations as a comparative case-study of different manifestations of colonial science in this period, examining how scholars in the Britain, the Russian Empire and the United States used formal and informal colonial links to Asia to pursue new research. It then moves to examine how the common problem of reconstructing this giant animal drew metropolitan scientific communities together, at least for a time. The construction of the Baluchitherium and Indricotherium illustrates the drives to expand research both imperially and internationally in the early-twentieth century, but also the continual problems in resources, institutionalization, transport and communication that could run up against scientific work.

Vertebrate paleontology was not readily incorporated into interdisciplinary activities at the University of Chicago. During the university’s first forty years serious disputes arose over the subject’s parameters and departmental affiliation. Only after World War II did a cooperative, interdisciplinary program emerge. Changes in biology and geology influenced that development, but even more important were local research and educational initiatives that provided the impetus and resources to create an innovative program.

Between 1909 and 1913, Berlin’s Museum für Naturkunde unearthed more than 225 tons of fossils in former German East Africa and transported them to Berlin. Among them were the bones of Brachiosaurus brancai, which would eventually become the biggest mounted dinosaur in the world. By analyzing the social and communicative strategies that made this expedition possible, this paper aims to reveal several aspects of natural history knowledge production at the end of the long nineteenth century. Using rhetoric, the director of (...) the Geological–Paleontological Museum in Berlin, Wilhelm von Branca, conducted a highly successful campaign to market the dinosaurs in Prussia and to convince public opinion and the Prussian central state of the value of paleontology. He fired the Prussian imagination and took advantage of the competitive urge to emulate American paleontology and industry. This work examines how his public relations strategies shaped the German biological “landscape” of the first decades of the twentieth century. It asks: when and under what conditions did paleontology successfully appeal to the public? How does communication dictate, shape, and constrain the development of a specific epistemic agenda? And what kind of power do the public and money have? (shrink)

Six schools of thought can be detected in the development of evolutionary theory in German paleontology between 1859 and World War II. Most paleontologists were hardly affected in their research by Darwin's Origin of Species. The traditionalists accepted evolution within lower taxa but not for organisms in general. They also rejected Darwin's theory of selection. The early Darwinians accepted Darwin's theory of transmutation and theory of selection as axioms and applied them fruitfully to the fossil record, thereby laying the (...) foundation for the new research areas of phylogeny and paleo-biology. The enthusiasm of the early Darwinians faded when the fossil record and the problems of its interpretion became more widely known. The pluralists of the turn of the century invented and adopted a wealth of hypothetical mechanisms in order to explain individual features of the fossil record. They failed, however, to provide one coherent theory. Dissatisfaction with this situation led to adoption of a dogmatic neo-Lamarckism, which was regarded as a coherent theory providing a fruitful research program. The rejection of the Lamarckian mechanism early in this century left paleontologists with only one kind of evolutionary mechanism: inner causes.Like many neo-Lamarckians several orthogeneticists were highly interested in adaptation and did not see any contradiction between the inner causes of evolution and adaptation. The dominance of stratigraphical research programs in paleontology led in the 1930s and 1940s to a decrease in interest in adaptation. Stratigraphical records of taxa were accepted as meaningful in the context of evolutionary theory. Orthogenesis and the new concepts of saltation and cyclicism were amalgamated into one theory : typostrophism. This theory dominated German paleontology for decades after the war and only recently has the synthetic theory been seriously considered.Evolution was never very intensively discussed in German paleontology in the hundred years after Darwin's book. Most information used here comes from textbooks or from papers given on special occasions. It has been impossible to summarize how members of one school defended their views or discussed the ideas of competing schools. (shrink)

The relatively late acceptance of Darwinism in German biology and paleontology is frequently attributed to a lingering of Lamarckism, a persisting influence of German idealistic Naturphilosophie and Goethean romanticism. These factors are largely held responsible for the vitalism underlying theories of saltational and orthogenetic evolutionary change that characterize the writings of many German paleontologists during the first half of the 20th century. A prominent exponent of that tradition was Karl Beurlen, who is credited with having been the first German (...) paleontologist to present a full-fledged theory of saltational evolution and orthogenetic change. A review of Beurlen's writings reveals motives and concerns far more complex, however, and firmly rooted in contemporary völkisch thought and Aryan Science. Beurlen's mature theory of evolution can indeed be understood as his own contribution to Aryan Geology and Biology, tainted as it was with National-Socialist ideology. Evolutionary biologists of the time who opposed the theories of Beurlen and likeminded authors, i.e., idealistic morphology, typology, saltational change, orthogenesis and cyclism did so on Darwinian principles, which ultimately prevailed. But at the time when the battle was fought, their adherence to the principle of natural selection was likewise ideologically tainted, namely in terms of racial theory. National-Socialist ideology was unable to forge a unity of evolutionary theory in Germany even amongst those of its proponents who endorsed this ideology. (shrink)

This paper examines Karl Alfred von Zittel’s practice in order to uncover the roots of so-called idiographic paleontology. The great American paleontologist Stephen Jay Gould (1941–2002) defined the discipline of idiographic paleontology as illustration and description of the morphological features of extinct species. However, this approach does not investigate macroevolutionary patterns and processes. On the contrary, the paleobiological revolution of the 1970s implemented an epistemic methodology that illustrates macrovelutionary patterns and laws by combining idiographic data with a nomothetic (...) form of explanation. This article elucidates the features of the idiographic data as well as the acquired knowledge coupled with this approach. First of all, Heinrich G. Bronn’s (1800–1862) statistical method is analyzed. Zittel’s practice arose as a reaction against the approximate conclusions reached by Bronn’s quantitative approach. Second, the details of Zittel’s methodology are described in order to bring out its peculiarities. The microscope played a pivotal role in creating and forming Zittel’s morphological data. This analysis sheds new light on the reasons behind the so-called ideographic paleontology, thus revising Gould’s historical reconstruction, as well as on the notion of paleontological data. However, even though Zittel aimed at reaching precise and stable conclusions, his data cannot be used for elucidating evolutionary mechanisms: they are scientific in a purely descriptive sense, but completely useless for biological investigations. Finally, this paper examines how Zittel’s methodology affects the contemporary paleobiological enterprise and thereby reflects upon the notion of natural history. (shrink)

Simon Conway Morris, noted Cambridge University paleontologist, argues that in evolutionary natural history humans (or beings rather like humans) are an inevitable outcome of the developing speciating processes over millennia; humans are “inherent” in the system. This claim, in marked contrast to claims about contingency made by other prominent paleontologists, is based on numerous remarkable convergences—similar trends found repeatedly in evolutionary history. Conway Morris concludes approaching a natural theology. His argument is powerful and informed. But does it face adequately the (...) surprising events in such history, particularly notable in unexpected co‐options that redirect the course of life? The challenge to understand how humans are both on a continuum with other species and also utterly different remains a central puzzle in paleontology. (shrink)

Whereas historiography of the debates on “early man in America” isolates Florentino Ameghino's ideas on human evolution from his paleontological and geological work, this paper presents Ameghino's ideas on human ancestors in regard to the controversies over the origin and dispersion of mammals. Therefore, this paper analyzes the constitution of paleontology in Argentina at the end of nineteenth century by describing, firstly, the Ameghino brothers' organization of research. By tackling this aspect I want also to discuss the place of (...) science in late nineteenth-century Argentina. Secondly, I will sketch “Ameghino's ideas” about Patagonia as a center of distribution of mammals, the age of Patagonian strata, and the South American origin of humankind. The Ameghino brothers' logistics of fieldwork created not only the means for finding a remarkable fossil fauna but also a trap that undermined their scientific credibility. Therefore, I will focus on the problem of fieldwork in “distant” places and of scientific wandering in Patagonia. In the polemics presented here, language, transportation systems, visual representations, and technical devices were crucial elements for the creation of paleontological objects. -/- . (shrink)

The fossil record is paleontology’s great resource, telling us virtually everything we know about the past history of life. This record, which has been accumulating since the beginning of paleontology as a professional discipline in the early nineteenth century, is a collection of objects. The fossil record exists literally, in the specimen drawers where fossils are kept, and figuratively, in the illustrations and records of fossils compiled in paleontological atlases and compendia. However, as has become increasingly clear since (...) the later twentieth century, the fossil record is also a record of data. Paleontologists now routinely abstract information from the physical fossil record to construct databases that serve as the basis for quantitative analysis of patterns in the history of life. What is the significance of this distinction? While it is often assumed that the orientation towards treating the fossil record as a record of data is an innovation of the computer age, it turns out that nineteenth century paleontology was substantially “data driven.” This paper traces the evolution of data practices and analyses in paleontology, primarily through examination of the compendia in which the fossil record has been recorded over the past 200 years. I argue that the transition towards conceptualizing the fossil record as a record of data began long before the emergence of the technologies associated with modern databases (such as digital computers and modern statistical methods). I will also argue that this history reveals how new forms of visual representation were associated with the transition from seeing the fossil record as a record of objects to one of data or information, which allowed paleontologists to make new visual arguments about their data. While these practices and techniques have become increasingly sophisticated in recent decades, I will show that their basic methodology was in place over a century ago, and that, in a sense, paleontology has always been a “data driven” science.

The growing interest and major advances of the last decades in evolutionary developmental biology (EvoDevo) have led to the recognition of the incompleteness of the Modern Synthesis of evolutionary theory. Here we discuss how paleontology makes significant contributions to integrate evolution and development. First, extinct organisms often inform us about developmental processes by showing a combination of features unrecorded in living species. We illustrate this point using the vertebrate fossil record and studies relating bone ossification to life history traits. (...) Second, we discuss exceptionally preserved fossils that document rare ontogenetic sequences and illustrate this case with the patterns of heterochrony observed in Cambrian crustacean larvae preserved three-dimensionally. Third, most fossils potentially document the evolutionary patterns of allometry and modularity, as well as some of the (paleo)ecological factors that had influenced them. The temporal persistence of adaptive patterns in rodent evolution serves to address the importance of ecological constraints in evolution. Fourth, we discuss how the macroevolutionary patterns observed in the tetrapod limb, in the mammal molar proportions, and in the molluscan shell provide independent tests of the validity of morphogenetic models proposed on living species. Reciprocally, these macroevolutionary patterns often act as a source of inspiration to investigate the underlying rules of development, because, at the end, they are the patterns that the neo-Darwinian theory was unable to account for.

I analyze the epistemic strategies used by paleontologists (between 1830–1930) to reconstruct features of ancient organisms from fossilized bodies and footprints by presenting two heuristics: (1) a “claim of harmony” which posits the harmonious interaction of natural objects in order for complex systems to be simplified and (2) the “kintsugi heuristic” which is used inter-theoretically to explore new claims of harmony. I apply these to three successive historical cases: Georges Cuvier’s laws of correlation, the panpsychist paleontology of Edward Drinker (...) Cope, and the single-character approach of Henry Fairfield Osborn. (shrink)

David Sepkoski and Michael Ruse’s edited collection The Peolobiological Revolution covers the changes in paleontological science in the last half-century. The collection should be of interest to philosophers of science (particularly those interested in non-reductive unity) as well as historians. I give an overview of the content and major themes of the volume and draw some lessons for the philosophy of science along the way. In particular, I argue that the history of paleontology demands a new approach to philosophical (...) delineation of sciences. (shrink)

For several decades, a debate has been waged over how to interpret the significance of fossils from the Burgess Shale and Cambrian Explosion. Stephen Jay Gould argued that if the “tape of life” was rerun, then the resulting lineages would differ radically from what we find today, implying that humans are a happy accident of evolution. Simon Conway Morris argued that if the “tape of life” was rerun, the resulting lineages would be similar to what we now observe, implying that (...) intelligence would still emerge from an evolutionary process. Recent methodological innovations in paleontological practice call into question both positions and suggest that global claims about the history of life, whether in terms of essential contingency or predictable convergence, are unwarranted.
