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.

Mohammad Arkoun (1928-2010) Muslim intellectual, offered "Islamic Criticism" projects, "Applied Islamology" and finally the "Critical Rational Future" project "Negar" with the aim of reviewing and transforming the understanding of the religious text and offering solutions to overcome the decline of Islamic civilization. His main scheme is the critique of Islamic reason, but the methodology is Applied Islamology. Arkoun projects are one of the first projects in the Islamic-Arab world, which have read the religious text based on new Western approaches. Research (...) Methods and Questions: This study uses a descriptive-analytical approach to examine the impact and application of Western approaches in religious texts reading in the thought of Mohammad Arkoun. The questions considered in this research are: What are the most important practical approaches of Arkoun in religious texts reading? What is Arkoun 's aim using different Western approaches to read religious texts? What are Arkoun 's approaches in the Applied Islamology project? The aims of this research is to study the Western approaches considered by Arkoun in the field of religious texts reading and to examine the impact and application of Western approaches in the Applied Islamology project of Arkoun. Findings: Arkoun projects in particular Applied Islamology include a set of approaches such as structuralism, genealogy, poststructuralism, hermeneutics, etc. His ultimate aim in applying various Western approaches is to provide an active and capable methodology for critical of religious texts reading, definite break from dogmatic and Orientalist perspectives and also to replace these studies with studies based on positivist methods and traditional philology. Among all practical approaches of Arkoun in the field of reading religious texts, there are three approaches that have many manifestations in his thoughts and projects: First, the linguistic-semiotic approach to the study of the foundational age, second, Foucault's paleontological approach to read contemporary Islamic-Arab modern thought and third, Historical-Sociological Analysis for the study of Islam as a social phenomenon and the Events of the history of Islam after the Prophet (PBUH).

Paleontological evidence suggests that human artefacts with intentional markings might have originated already in the Lower Paleolithic, up to 500.000 years ago and well before the advent of ‘behavioural modernity’. These markings apparently did not serve instrumental, tool-like functions, nor do they appear to be forms of figurative art. Instead, they display abstract geometric patterns that potentially testify to an emerging ability of symbol use. In a variation on Ian Hacking’s speculative account of the possible role of “likeness-making” in the (...) evolution of human cognition and language, this essay explores the central role that the embodied processes of making and the collective practices of using such artefacts might have played in early human cognitive evolution. Two paradigmatic findings of Lower Paleolithic artefacts are discussed as tentative evidence of likenesses acting as material scaffolds in the emergence of symbolic reference-making. They might provide the link between basic abilities of mimesis and imitation and the development of modern language and thought. (shrink)

In paleontology, the discovery of funeral rites is an important factor in determining the degree of social awakening of a hominid. This awareness of death is an engine of social cohesion (uniting to resist disasters and enemies) and action (to do something to leave a trace). It is an important element of metaphysical reflection. This is also what gives the symbolic power to acts such as homicide and suicide. According to Plato, death is the separation of soul and body. (...) Finally freed from his fleshly prison, the immortal soul can freely reach the sky of Ideas, Eternity, the domain of philosophers. (cf. Phaedo). (shrink)

Humans experience a profound and indescribable emotion when they unearth artifacts from ancient times. Scientific disciplines like paleontology and archaeology reflect our curiosity and desire to understand the natural world’s past and evolutionary history. Physics also invests significant effort in exploring the origin and evolution of the universe. In social life, the study field of humanities also has journals about art history, such as the Art History or Journal of Art History. Through our shared thoughts and efforts to restore (...) humanities for the cause of ecological and biological conservation, we have discovered a picture of a kingfisher taken nearly a century ago by A. F. Skutch in The Condor. Obtaining such a vivid, genuine, and emotionally evocative image was no easy task. This image has the power to stir the thoughts and awaken the conscience of the viewer, emphasizing the importance of a vibrant environment. (shrink)

In both scientific and popular circles it is often said that we are in the midst of a sixth mass extinction. Although the urgency of our present environmental crises is not in doubt, such claims of a present mass extinction are highly controversial scientifically. Our aims are, first, to get to the bottom of this scientific debate by shedding philosophical light on the many conceptual and methodological challenges involved in answering this scientific question, and, second, to offer new philosophical perspectives (...) on what the value of asking this question has been — and whether that value persists today. We show that the conceptual challenges in defining ‘mass extinction’, uncertainties in past and present diversity assessments, and data incommensurabilities undermine a straightforward answer to the question of whether we are in, or entering, a sixth mass extinction today. More broadly we argue that an excessive focus on the mass extinction framing can be misleading for present conservation efforts and may lead us to miss out on the many other valuable insights that Earth’s deep time can offer in guiding our future.

There is a tendency to take mounted dinosaur skeletons at face value, as the raw data on which the science of paleontology is founded. But the truth is that mounted dinosaur skeletons are substantially intention-dependent—they are artifacts. More importantly, I argue, they are also substantially imagination-dependent: their production is substantially causally reliant on preparators’ creative imaginations, and their proper reception is predicated on audiences’ recreative imaginations. My main goal here is to show that dinosaur skeletal mounts are plausible candidates (...) for art-status. But, what is more, I think they are artworks—specifically, sculptures. (shrink)

The visuospatial system integrates inner and outer functional processes, organizing spatial, temporal, and social interactions between the brain, body, and environment. These processes involve sensorimotor networks like the eye–hand circuit, which is especially important to primates, given their reliance on vision and touch as primary sensory modalities and the use of the hands in social and environmental interactions. At the same time, visuospatial cognition is intimately connected with memory, self-awareness, and simulation capacity. In the present article, we review issues associated (...) with investigating visuospatial integration in extinct human groups through the use of anatomical and behavioral data gleaned from the paleontological and archaeological records. In modern humans, paleoneurological analyses have demonstrated noticeable and unique morphological changes in the parietal cortex, a region crucial to visuospatial management. Archaeological data provides information on hand–tool interaction, the spatial behavior of past populations, and their interaction with the environment. Visuospatial integration may represent a critical bridge between extended cognition, self-awareness, and social perception. As such, visuospatial functions are relevant to the hypothesis that human evolution is characterized by changes in brain–body–environment interactions and relations, which enhance integration between internal and external cognitive components through neural plasticity and the development of a specialized embodiment capacity. We therefore advocate the investigation of visuospatial functions in past populations through the paleoneurological study of anatomical elements and archaeological analysis of visuospatial behaviors.

The geosciences include a wide spectrum of disciplines ranging from paleontology to climate science, and involve studies of a vast range of spatial and temporal scales, from the deep-time history of microbial life to the future of a system no less immense and complex than the entire Earth. Modeling is thus a central and indispensable tool across the geosciences. Here, we review both the history and current state of model-based inquiry in the geosciences. Research in these fields makes use (...) of a wide variety of models, such as conceptual, physical, and numerical models, and more specifically cellular automata, artificial neural networks, agent-based models, coupled models, and hierarchical models. We note the increasing demands to incorporate biological and social systems into geoscience modeling, challenging the traditional boundaries of these fields. Understanding and articulating the many different sources of scientific uncertainty – and finding tools and methods to address them – has been at the forefront of most research in geoscience modeling. We discuss not only structuralmodel uncertainties, parameter uncertainties, and solution uncertainties, but also the diverse sources of uncertainty arising from the complex nature of geoscience systems themselves. Without an examination of the geosciences, our philosophies of science and our understanding of the nature of model-based science are incomplete. (shrink)

Drawing on many areas of expertise, from paleontology to psychology, Tomasello offers a plausible, evolutionary story abouthow our ancestors are likely to have developed cooperative behaviors and collaborative lifeways in order to survive and thrive.He also claims that this narrative explains why they would have begun to think in characteristically cooperative and moral ways,developing a “we is greater than me” [we>me] psychological orientation. Do the arguments offered support this extra claim? Thisarticle suggests that they do not. It seeks to (...) alleviate this shortcoming by drawing upon some conceptual resources offered bySartre’s Theory of Practical Ensembles. The centerpiece of the article consists of a detailed analysis of Sartre’s account of the genesisof the “group-in-fusion,” seeking to show that the genesis of a we-way of thinking in a group made up of many requires themediation of what Sartre calls a “third party” (le tiers). After closely examining Sartre’s treatment of the “third party” in theapocalyptic genesis of the “group-in-fusion,” I evaluate the success of this notion in resolving those questions that Tomasello’saccount raises while, at the same time, addressing the ontological question concerning the nature of the individual-grouprelation, in a way that suggests new and significant alternatives to standard dilemmas in contemporary social philosophy.

Creationists who object to evolution in the science curriculum of public schools often cite Jonathan Well’s book Icons of Evolution in their support (Wells 2000). In the third chapter of his book Wells claims that neither paleontological nor molecular evidence supports the thesis that the history of life is an evolutionary process of descent from preexisting ancestors. We argue that Wells inappropriately relies upon ambiguities inherent in the term ‘Darwinian’ and the phrase ‘Darwin’s theory’. Furthermore, he does not accurately distinguish (...) between the overwhelming evidence that supports the thesis of common descent and controversies that pertain to causal mechanisms such as natural selection. We also argue that Wells’ attempts to undermine the evidence in support of common descent are flawed and his characterization of the relevant data is misleading. In particular, his assessment of the ‘Cambrian explosion’ does not do justice to the fossil record. Nor do his selective references to debate about molecular and paleontological phylogenies constitute a case against common descent. We conclude that the fossil and molecular evidence is more than sufficient to warrant science educators to present common descent as a well-established scientific fact. We also argue that diagrams depicting the ‘tree of life’ can be pedagogically useful as simplified representations of the history of life. (shrink)

This paper will outline a series of changes in the archaeological record related to Hominins. I argue that these changes underlie the emergence of the capacity for strategic thinking. The paper will start by examining the foundation of technical skills found in primates, and then work through various phases of the archaeological and paleontological record. I argue that the key driver for the development of strategic thinking was the need to expand range sizes and cope with increasingly heterogeneous environments.

Despite an enormous philosophical literature on models in science, surprisingly little has been written about data models and how they are constructed. In this paper, I examine the case of how paleodiversity data models are constructed from the fossil data. In particular, I show how paleontologists are using various model-based techniques to correct the data. Drawing on this research, I argue for the following related theses: first, the ‘purity’ of a data model is not a measure of its epistemic reliability. (...) Instead it is the fidelity of the data that matters. Second, the fidelity of a data model in capturing the signal of interest is a matter of degree. Third, the fidelity of a data model can be improved ‘vicariously’, such as through the use of post hoc model-based correction techniques. And, fourth, data models, like theoretical models, should be assessed as adequate for particular purposes. (shrink)

Research in ecology and evolutionary biology (evo-eco) often tries to emulate the “hard” sciences such as physics and chemistry, but to many of its practitioners feels more like the “soft” sciences of psychology and sociology. I argue that this schizophrenic attitude is the result of lack of appreciation of the full consequences of the peculiarity of the evo-eco sciences as lying in between a-historical disciplines such as physics and completely historical ones as like paleontology. Furthermore, evo-eco researchers have gotten (...) stuck on mathematically appealing but philosophi- cally simplistic concepts such as null hypotheses and p-values defined according to the frequentist approach in statistics, with the consequence of having been unable to fully embrace the complexity and subtlety of the problems with which ecologists and evolutionary biologists deal with. I review and discuss some literature in ecology, philosophy of science and psychology to show that a more critical methodological attitude can be liberating for the evo-eco scientist and can lead to a more fecund and enjoyable practice of ecology and evolutionary biology. With this aim, I briefly cover concepts such as the method of multiple hypotheses, Bayesian analysis, and strong inference. (shrink)

In contrast to many other models of human evolution the "balance of power" theory of Alexander has a clear answer to the question why a runaway selection process for unique social and moral capacities occurred in our ancestry only and not in other species: "ecological dominance" is hypothesized to have diminished the effects of "extrinsic" forces of natural selection such that within-species, intergroup competition increased (Alexander, 1989). Alexander seems to be wrong, however, in his claim that already the common HUCHIBO (...) (Humans, Chimps, Bonobo's)-ancestor has crossed the ecological dominance barrier. In this paper an adapted version of Alexander's model is presented and several different ways are proposed to make this adapted version testable. A preliminary survey of the available paleontological and paleoecological data suggests that there is some evidence of a less vulnerable position towards predators in early Homo and that there are clear signs related to a crossing of the ecological dominance barrier in Homo sapiens sapiens.

Chimpanzee language studies have generated much heated controversy, as Roger Fouts can attest from firsthand experience. Perhaps this is because language is usually considered to be what truly distinguishes humans from apes. If chimps can indeed be taught the rudiments of language, then the difference between them and us is not as great as we might have thought. It is a matter of degree rather than kind, a continuity, and our species is not so special after all. The advantage of (...) this continuity thesis, as Fouts has emphasized, is that it conforms to the general tenets of evolutionary theory, and fits well with the evidence from paleontology and genetics that suggests that apes and humans are close cousins. It also .. (shrink)

In the first part of this article we survey general similarities and differences between biological and social macroevolution. In the second (and main) part, we consider a concrete mathematical model capable of describing important features of both biological and social macroevolution. In mathematical models of historical macrodynamics, a hyperbolic pattern of world population growth arises from non-linear, second-order positive feedback between demographic growth and technological development. This is more or less identical with the working of the collective learning mechanism. Based (...) on diverse paleontological data and an analogy with macrosociological models, we suggest that the hyperbolic character of biodiversity growth can be similarly accounted for by non-linear, second-order positive feedback between diversity growth and the complexity of community structure, suggesting the presence within the biosphere of a certain analogue of the collective learning mechanism. We discuss how such positive feedback mechanisms can be modelled mathematically. (shrink)

Biology has improved a lot over the centuries. The success of developmental biology is huge in every field of physiology, anatomy, paleontology, embryology. The term homology has not been used in biology for a long time. The need for homology in biology is understandable. I have discussed in this paper the necessity of homology in the field of biology and argued that it is unreasonable to refer to homology as evidence of Darwinism, both philosophically and biologically. This paper evaluates (...) homology in the light of the philosophy of biology as evidence for evolution. (shrink)
