We present the first comprehensive taxonomic revision and review the biology of the olingos, the endemic Neotropical procyonid genus Bassaricyon, based on most specimens available in museums, and with data derived from anatomy, morphometrics, mitochondrial and nuclear DNA, field observations, and geographic range modeling. Species of Bassaricyon are primarily forest-living, arboreal, nocturnal, frugivorous, and solitary, and have one young at a time. We demonstrate that four olingo species can be recognized, including a Central American species (Bassaricyon gabbii), (...) lowland species with eastern, cis-Andean (Bassaricyon alleni) and western, trans-Andean (Bassaricyon medius) distributions, and a species endemic to cloud forests in the Andes. The oldest evolutionary divergence in the genus is between this last species, endemic to the Andes of Colombia and Ecuador, and all other species, which occur in lower elevation habitats. Surprisingly, this Andean endemic species, which we call the Olinguito, has never been previously described; it represents a new species in the order Carnivora and is the smallest living member of the family Procyonidae. We report on the biology of this new species based on information from museum specimens, niche modeling, and fieldwork in western Ecuador, and describe four Olinguito subspecies based on morphological distinctions across different regions of the Northern Andes.

Using Giddens’s structuration theory and empirical data from a study with social enterprise stakeholders, the article explores how social entrepreneurs and the structure co-create one another. We show that the development of the contemporary significance of social entrepreneurialism lies in a combination of complex context-specific structural forces and the activities of agents who initiate, demand, and impose change. Social entrepreneurs intentionally tackle social challenges, but their actions bring unintentional results, such as the transfer of state responsibilities onto communities. Direct outputs (...) of their activities introduce indirect outcomes, bringing wider changes in culture and policy. The evolving nature of entrepreneurship and a number of factors that interplay in time and space, and enable and constrain social entrepreneurs, confirm the applicability of Giddens’s theory in the field of social entrepreneurship. The originality of this article derives from revealing mechanisms that enable social entrepreneurs to emerge and reasons for structural change. We also build a “co-creation model of structure and agency” that can be used to “engineer” the process of social entrepreneurship. (shrink)

This collection of original essays--by philosophers of biology, biologists, and cognitive scientists--provides a wide range of perspectives on species. Including contributions from David Hull, John Dupre, David Nanney, Kevin de Queiroz, and Kim Sterelny, amongst others, this book has become especially well-known for the three essays it contains on the homeostatic property cluster view of natural kinds, papers by Richard Boyd, Paul Griffiths, and Robert A. Wilson.

Currently, some philosophers and technicians propose to change the fundamental constitution of Homo sapiens, as by significantly altering the genome, implanting microchips in the brain, and pursuing related techniques. Among these proposals are aspirations to guide humanity’s evolution into new species. Some philosophers have countered that such species alteration is unethical and have proposed international policies to protect species integrity; yet, it remains unclear on what basis such right to species integrity would rest. An answer may (...) come from an unexpected angle of rights issues: Some cultures have indicated that they want no part of our technological culture, preferring to retain their practices. Yet, rights documents do not explicitly establish that any individual has a right to species integrity. Careful interpretation of rights documents nonetheless reveals that such a right to species integrity is implicit. Interpreting these so as to reveal this needed right is also necessary to retain the foundations of rights documents and institutions. Further, acknowledging a right of species integrity could mean, because of practicalities, a limit to the freedom of proponents to implement proposals to manipulate the species. (shrink)

The new millennium has opened with a perfectly splendid decade of scholarship relating to the ‘Species Problem’. So, at least we now have a clear idea of what this is, but still no clear solution that will suit both biologists and philosophers. Richards has recently attempted to capture this story and to fill the void with two projects in one book. The first project is a descriptive and analytical history of the problem, which provides links to other recent works (...) and thereby allows one to fully reconstruct the literature. The second is prescriptive and presents Richards’s solution via a ‘division of labour in a conceptual framework’ followed by recapitulation and conclusions. It is my assessment as presented here that the first project will appeal more to biologists and the second one to philosophers. There is much of value in Richards approach including an excellent evaluation of the essentialism story in the descriptive project and clear exposition of several key issues such as the ‘species-as-individuals’ versus ‘species-as-categories’ debate which are covered in the second project. Interesting and informative as these arguments undoubtedly are, something still seems to be missing here. In this essay I suggest that this perception arises from Richards’ failure to embrace ideas about the importance of relativity and contingency in species definitions and further that his new conceptual framework lacks one hierarchical level to link overarching lineage concepts of species as evolutionary units with practical definitions for their recognition. In my view, the missing link is reproductive isolation and I conclude my review by presenting a prescriptive project for biologists to balance the one that Richards has delivered to philosophers.

We attempt to defend the species-as-individuals hypothesis by examining the logical role played by the binomials (e.g., "Homo sapiens," "Pinus ponderosa") in biological discourse about species. Those who contend that the binomials can be properly understood as functioning in biological theory as singular terms opt for an objectual account of species and view species as individuals. Those who contend that the binomials can in principle be eliminated from biological theory in favor of predicate expressions opt for (...) a predicative account of species and view species as kinds. We contend that biologists' talk about species is talk about species as individuals, and we conclude that the most plausible account of species is an objectual account. (shrink)

This paper examines the way in which Locke's deep and longstanding interest in the non-European world contributed to his views on species and their classification. The evidence for Locke's curiosity about the non-European world, especially his fascination with seventeenth-century travel literature, is presented and evaluated. I claim that this personal interest of Locke's almost certainly influenced the metaphysical and epistemological positions he develops in the Essay. I look to Locke's theory of species taxonomy for proof of this. I (...) argue that Locke uses evidence gathered from the non-European world to (1) show that in taxonomizing objects we rely on their sensible qualities rather than their real essences and to (2) undermine Scholastic Aristotelian views about a mind-independent species/genera structure to the world.

Gene editing technologies such as CRISPR hold the promise to solve many of the challenges in industrial salmon farming. However, for the technology to be taken into use, it has to be deemed socially and morally acceptable. Whereas older gene modification technologies have been met with much public resistance, there are hopes that CRISPR might change the debate, since it does not require inserting genes from other organisms and can therefore be considered less invasive and more natural. Though the concept (...) of naturalness is contested, it is frequently appealed to in science communication and explanations of why the public should be more inclined to accept CRISPR-edited organisms than GMOs. Farmed salmon is a good case for considering our intuitions about naturalness, since it is a recently domesticated species, far removed from its cousin in the wild. The study presented here consists of 19 interviews with stakeholders and 4 focus groups with consumers. A major finding is that the concept of naturalness is not considered crucial when it comes to determining the acceptability of using CRISPR on farmed salmon; what is significant is rather whether its use is consistent with a respectful treatment of them.

Species are central to biology, but there is currently no agreement on what the adequate species concept should be, and many have adopted a pluralist stance: different species concepts will be required for different purposes. This thesis is a multidimensional analysis of species pluralism. First I explicate how pluralism differs monism and relativism. I then consider the history of species pluralism. I argue that we must re-frame the species problem, and that re-evaluating Aristotle's role (...) in the histories of systematics can shed light on pluralism. Next I consider different forms of pluralism: evolutionary and extra-evolutionary species pluralism, which differ in their stance on evolutionary theory. I show that pluralism is more than a debate about the species category, but a debate about which concepts are legitimate and a claim about how they interact with one another. Following that, I consider what sort of ontology is required for different forms of species pluralism. I argue that pluralists who deny the unity of biology will require a further plurality of frameworks, while those that ground their pluralism in evolution need only one framework. Finally, I consider what pluralism means for biological practice. I argue that species concepts are tools, and reflect on how pluralism can illuminate the way systematists approach the discovery of new species of yeast. Pluralism can make sense of the way species concepts are used, and can be developed to aid researchers in thinking about how to use the right tools for the right jobs. (shrink)

In The Origin of Species (1859) Darwin challenged many of the most deeply-held beliefs of the Western world. Arguing for a material, not divine, origin of species, he showed that new species are achieved by "natural selection." The Origin communicates the enthusiasm of original thinking in an open, descriptive style, and Darwin's emphasis on the value of diversity speaks more strongly now than ever. As well as a stimulating introduction and detailed notes, this edition offers a register (...) of the many writers referred to by Darwin in the text. (shrink)

Abstract:Should we use modern bioengineering techniques to design species? An instrumentalist account of species’ value offers permissive guidance. But what if species exemplify final value? Is it always very good to create new species? Is it always very wrong to blend or modify existing species? In this paper, I argue that both extremes are implausible. However, final value theories struggle to deliver a flexible, moderate treatment of these issues, and so the ethics of designing (...) class='Hi'>species presents a challenge for final value theorists. Fortunately, a design-based account of the value of species has the resources to offer plausible, nuanced, context-sensitive guidance on the ethics of designing species. It holds that designing species is sometimes very bad, sometimes quite good, and sometimes neither very good nor very bad. The plausibility of these results lends credibility to the design-based framework, and gives final value theorists reason to prefer the design-based approach. (shrink)

Biological science uses multiple species concepts. Order can be brought to this diversity if we recognize two key features. First, any given species concept is likely to have a patchwork structure, generated by repeated application of the concept to new domains. We illustrate this by showing how two species concepts (biological and ecological) have been modified from their initial eukaryotic applications to apply to prokaryotes. Second, both within and between patches, distinct species concepts may interact and (...) hybridize. We thus defend a semantic picture of the species concept as a collection of interacting patchwork structures. Thus, although not all uses of the term pick out the same kind of unit in nature, the diversity of uses reflects something more than mere polysemy. We suggest that the emphasis on the use of species to pick out natural units is itself problematic, because that is not the term’s sole function. In particular, species concepts are used to manage inquiry into processes of speciation, even when these processes do not produce clearly delimited species. (shrink)

We are causing species to go extinct at extraordinary rates, altering existing species in unprecedented ways and creating entirely new species. More than ever before, we require an ethic of species to guide our interactions with them. In this book, Ronald L. Sandler examines the value of species and the ethical significance of species boundaries and discusses what these mean for species preservation in the light of global climate change, species engineering and (...) human enhancement. He argues that species possess several varieties of value, but they are not sacred. It is sometimes permissible to alter species, let them go extinct and invent new ones. Philosophically rigorous, accessible and illustrated with examples drawn from contemporary science, this book will be of interest to students of philosophy, bioethics, environmental ethics and conservation biology.

Plant and animal species are information-processing entities of such complexity, integration, and adaptive competence that it may be scientifically fruitful to consider them intelligent. The possibility arises from the analogy between learning and evolution, and from recent developments in evolutionary science, psychology and cognitive science. Species are now described as spatiotemporally localized individuals in an expanded hierarchy of biological entities. Intentional and cognitive abilities are now ascribed to animal, human, and artificial intelligence systems that process information adaptively, and (...) that manifest problem-solving abilities. The structural and functional similarities between such systems and species are extensive, although they “are usually obscured by population-genetic metaphors that have nonetheless contributed much to our understanding of evolution.In this target article, I use Sewall Wright's notion of the “adaptive landscape” to compare the performances of evolving species to those of intelligent organisms. With regard to their adaptive achievements and the kinds of processes by which they are achieved, biological species compare very favorably to intelligent animals by virtue of interactions between populations and their environments, between ontogeny and phylogeny, and between natural, interdemic, organic, and species selection. Addressing the question of whether species are intelligent could help to refine our ideas about species, evolution, and intelligence, and could open new lines of empirical and theoretical inquiry in many disciplines.

This paper aims to offer a new argument in defence bacterial species pluralism. To do so, I shall first present the particular issues derived from the conflict between the non-theoretical understanding of species as units of classification and the theoretical comprehension of them as units of evolution. Secondly, I shall justify the necessity of the concept of species for the bacterial world, and show how medicine and endosymbiotic evolutionary theory make use of different concepts of bacterial (...) class='Hi'>species due to their distinctive purposes. Finally, I shall show how my argument provides a new source of defence for bacterial pluralism. (shrink)

Traditionally, species have been treated as classes or kinds in philosophical discussions of systematics and evolutionary biology. Recently a number of biologists and philosophers have proposed a drastic revision of this traditional ontological categorization. They have argued that species ought be viewed as individuals rather than as classes or natural kinds. In this paper an attempt is made to show that (a) the reasons advanced in support of this new view of species are not persuasive, (b) a (...) reasonable explication can be given of the treatment of species as classes that is consistent with current theory and practice in evolutionary biology and systematics, and (c) that once certain confusions concerning the species concept have been clarified, there are good theoretical grounds for maintaining that species are best viewed as classes or kinds.

Robots equipped with artificial intelligence pose a huge challenge to traditional ontological differentiations between the spheres of the human and the non-human. Drawing mainly from neo-animistic and perspectivist approaches in anthropology and science and technology studies, the paper explores the potential of new forms of interconnectedness and rhizomatic entanglements between humans and a world transcending the boundaries between species and material spheres. We argue that intelligent robots meet virtually all criteria Western biology came up with to define ‘life’ and (...) that it ultimately makes sense to recognize them as a new species that is part of our social universe. Contrasting dualistic concepts of man and nature with a monistic approach, we show that traditional properties of life (agency, self-replication, etc.) may apply to artefacts and that, once we accept the idea that social relationships are ultimately open connections to matter of any kind, the seemingly strict boundaries between species and material spheres can no longer be sustained. Instead, we propose to include ‘matter’ and ideas into the sphere of the social as agents in their own right to form a _relational ontology of multi-species assemblages_ (ROMA). (shrink)

This paper proposes a new and testable view about the nature of species and other evolving lineages, according to which they are feedback systems. On this view, it is a mistake to think gene flow, niche sharing, and trait frequency similarities between populations are among variables that interact to cause some further downstream variable that distinguishes evolving lineages from each other, some sort of “species cohesion” for example. Instead, gene flow, niche sharing, similarities between populations, and other causal (...) variables feed into each other—instances of these at earlier times help cause instances of these same variables at later times. And any lineage-identifying cohesion just is the recurrence or cycling of these feedback relations within metapopulations over generations. Such cohesion can then be represented as variable M within multi-dimensional variable spaces, where values of M vary dynamically with the frequency and magnitude of feedback relations. Related conditions for being a species or other evolving lineage are then clarified. To argue for the development and testing of this view, the paper shows how it improves upon others. (shrink)

For more than fifty years, taxonomists have proposed numerous alternative definitions of species while they searched for a unique, comprehensive, and persuasive definition. This monograph shows that these efforts have been unnecessary, and indeed have provably been a pursuit of a will o’ the wisp because they have failed to recognize the theoretical impossibility of what they seek to accomplish. A clear and rigorous understanding of the logic underlying species definition leads both to a recognition of the inescapable (...) ambiguity that affects the definition of species, and to a framework-relative approach to species definition that is logically compelling, i.e., cannot not be accepted without inconsistency. An appendix reflects upon the conclusions reached, applying them in an intellectually whimsical taxonomic thought experiment that conjectures the possibility of an emerging new human species.

Lists of species underpin many fields of human endeavour, but there are currently no universally accepted principles for deciding which biological species should be accepted when there are alternative taxonomic treatments (and, by extension, which scientific names should be applied to those species). As improvements in information technology make it easier to communicate, access, and aggregate biodiversity information, there is a need for a framework that helps taxonomists and the users of taxonomy decide which taxa and names (...) should be used by society whilst continuing to encourage taxonomic research that leads to new species discoveries, new knowledge of species relationships, and the refinement of existing species concepts. Here, we present 10 principles that can underpin such a governance framework, namely (i) the species list must be based on science and free from nontaxonomic considerations and interference, (ii) governance of the species list must aim for community support and use, (iii) all decisions about list composition must be transparent, (iv) the governance of validated lists of species is separate from the governance of the names of taxa, (v) governance of lists of accepted species must not constrain academic freedom, (vi) the set of criteria considered sufficient to recognise species boundaries may appropriately vary between different taxonomic groups but should be consistent when possible, (vii) a global list must balance conflicting needs for currency and stability by having archived versions, (viii) contributors need appropriate recognition, (ix) list content should be traceable, and (x) a global listing process needs both to encompass global diversity and to accommodate local knowledge of that diversity. We conclude by outlining issues that must be resolved if such a system of taxonomic list governance and a unified list of accepted scientific names generated are to be universally adopted. (shrink)

Species pluralism allows for multiple species concepts. Given the overwhelming number of such concepts, this seems like an obvious interpretation of how `species' is used in contemporary biology. But why has it taken so long for this approach to be considered? I argue that part of the reason pluralism was overlooked due to the widespread use of a particular rhetorical strategy developed by Ernst Mayr. This strategy provided a framework for debates about the correct conception of (...) class='Hi'>species. That is, the strategy offered a means of comparing modern concepts with a monistic-essentialist understanding of species. I ask what would happen if we replaced this concept with Aristotle's own pluralist-essentialist understanding of species. As recent scholarship shows, Aristotle's philosophy of biology allows for an approach to classification that is in practice highly pluralistic. From this new framework we can understand what sort of assumptions are at stake between modern forms of species pluralism. My analysis shows that the essentialist story told by Mayr and others left us asking the wrong questions about how to conceive of species in an evolutionary world. Having a deeper understanding of Aristotle's approach to the classification of animals allows us to shift focus from the so-called species problem in order to raise four issues that are relevant to current debates. These are questions about: the explanatory power of taxonomic ranks, the importance of the species category problem, whether species are constituted by intrinsic or extrinsic properties, and how to interpret the ``cross-cutting'' metaphor endemic to the pluralist literature. In order to get to these questions I will first explain what sort of claim species pluralism is at the most general level, and a gloss on the standard interpretation of the historical shift from species monism to species pluralism. (shrink)

Arguments against essentialism in biology rely strongly on a claim that modern biology abandoned Aristotle's notion of a species as a class of necessary and sufficient properties. However, neither his theory of essentialism, nor his logical definition of species and genus (eidos and genos) play much of a role in biological research and taxonomy, including his own. The objections to natural kinds thinking by early twentieth century biologists wrestling with the new genetics overlooked the fact that species (...) have typical developmental cycles and most have a large shared genetic component. These are the "what-it-is-to-be" members of that species. An intrinsic biological essentialism does not commit us to Aristotelian notions, nor even modern notions, of essence. There is a long-standing definition of "species" and its precursor notions that goes back to the Greeks, and which Darwin and pretty well all biologists since him share, that I call the Generative Conception of Species. It relies on there being a shared generative power that makes progeny resemble parents. The "what-it-is-to-be" a member of that species is that developmental type, mistakes in development notwithstanding. Moreover, such "essences" have always been understood to include deviations from the type. Finally, I shall examine some implications of the collapse of the narrative about essences in biology.

This article characterizes various species concepts in terms of set-theoretic models that license biological inferences and illustrates the logical connections among different species concepts. Species in this construal are abstract models, rather than biological or even tangible entities, and relate to individual organisms via representation, rather than the membership or mereological whole/part relationship. The proposal sheds new light on vexed issues of species and situates them within broader philosophical contexts of model selection, scientific representation, and scientific (...) realism. (shrink)

Over the decades, there has been substantial empirical evidence showing that the unity of species cannot be maintained by gene flow. The biological species concept is inconclusive on this point. The suggestion is made that the unity of species is maintained rather by selection constantly spreading new alleles throughout the species, or bygene circulation. There is a lack in conceptual distinction between gene flow and gene circulation which lies at the heart of the problem. The concept (...) of gene circulation also sheds some new light on the problem of typology and on such a broad concept as evolution. A new species definition is proposed. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Species Counterpoint:Darwin and the Evolution of FormsRandall Everett AllsupMy intention is to tell of bodies changed to different forms; the gods, who made the changes, will help me—or so I hope—with a poem that runs from the World's beginning to our own days.1I.A recent article in a progressive monthly magazine asked by way of a thesis, "Whose music is the blues?" Under the title, the tag line read, (...) "2003 is the 'Year of the Blues.' But as a music born of oppression becomes a feel-good soundtrack for white America, just what are we celebrating?"2 I recall feeling puzzled by this rather old-fashioned topic of investigation. Anyone with access to the Internet knows that music is not for one group or another. Global file sharing has made ownership as easy as, well, sharing a file. Furthermore, the tendency to depart from ancestral forms, whether as rebellious teenagers, rock guitarists, or both, seems genetically built into us. Life is a metamorphosis and music—like life—evolves.To advance the notion that music is made for one people and not another, that it has absolute or essential qualities, opens a terribly large can of worms. We know, for example, that identity and music are linked, but the relationship is not [End Page 159] mono-directional, causal, or fixed. My relationship to the blues or Broadway show tunes for that matter is defined somewhere within a dense web of group associations, educational opportunities, even closet desires. With regard to psychological research on identity, slippery and impermanent as identity is, this research is really about similarities.3 Conservative in this light, such studies look for commonalities: their goal is to identify "what is."4Fear is often the dominant response to the evolution of a cherished form. Change, however, holds equal parts fear and promise. The Chinese word for crisis, wei-ji, means "opportunity with danger." This essay will contextualize the latter, but focus on the former. It is worth asking, for example, what might result from an examination of anomalies? Rather than attempt to identify "what is," such an inquiry would be concerned with "what else" [the abnormality] as well as "what might be" [the opportunity]. Located, I think, within the anomalies and mutations that seem to fit so well our globally connected world are new codes, altered methods for self-understanding, and interaction in the arts.Charles Darwin and The Origins of Species will provide the conceptual framework for this discussion.5 To look for help in the work of Darwin will require a crossbreeding of scientific theory and metaphor, a cross-pollination of hypothesis and the hypothetical. We will look at how the production of new forms, particularly musical forms, is shaped. Speaking metaphorically, a work of art or entertainment can be seen as an adaptation to and of its environment. We know that cultural products, like all living species, are not permanent entities. Change, Darwin stressed, carries with it purpose. To that end, he looked for variation to help him understand how and why an organism or system developed the way it did. What might be revealed if we apply this procedure to the field of music and music education? We might see eco-systems in various stages of growth, health, and decline. A look at musical forms as mutable, living creations that spring from and reflect a particular condition raises interesting questions about place and purpose.II.Only a hundred and fifty years ago, a single event—a theory!—precipitated a cultural crisis that threw down two thousand years of scientific and philosophic thought. The popular revolt that Charles Darwin's The Origin of Species fueled (and continues to fuel) called into question fundamental beliefs about how the world is made. Darwin's theory that matter and energy are in steady flux, that life is in need of constant variation, implied that fixed or universal truths are nothing more than comforts created by the mind. The Origin of Species was therefore more than a scientific revolution.6 A core tenet of Western culture was challenged by its publication: the so-called immaterial spirit, whether viewed in the [End...

A reading of a sample of taxonomical papers leads to the conclusion that new species identification is both taxonomically plausible and philosophically incoherent. As a result, taxonomy becomes a science that apparently violates a necessary condition of its rationality. It is this apparent violation that is the focus of the philosophical debate, a debate whose goal for taxonomy is theoretical coherence at a global level. In this paper, I assess the appropriateness of this goal.

This paper outlines an alternative perspective on species that avoids some of the underlying assumptions held by the BSC and other gene-centred species concepts. It begins with a characterisation of the species problem and some of the assumptions underpinning conceptions of species. In particular, the underlying bias of some conceptions (such as the BSC) to focus exclusively on the adult stage of the life cycle in articulating what a species is.
