  1. Speciation and Macroevolution.Anya Plutynski - 2008 - In Sahotra Sarkar & Anya Plutynski (eds.), A Companion to the Philosophy of Biology. Blackwell's/Routledge.
    Speciation is the process by which one or more species arises from a common ancestor, and “macroevolution” refers to patterns and processes at and above the species level – or, transitions in higher taxa, such as new families, phyla or genera. “Macroevolution” is contrasted with “microevolution,” evolutionary change within populations, due to migration, assortative mating, selection, mutation and drift. In the evolutionary synthesis of the 1930’s and 40’s, Haldane , Dobzhansky , Mayr , and Simpson argued that the origin (...)

  2. The Dimensions, Modes and Definitions of Species and Speciation.John S. Wilkins - 2007 - Biology and Philosophy 22 (2):247-266.
    Speciation is an aspect of evolutionary biology that has received little philosophical attention apart from articles mainly by biologists such as Mayr (1988). The role of speciation as a terminus a quo for the individuality of species or in the context of punctuated equilibrium theory has been discussed, but not the nature of speciation events themselves. It is the task of this paper to attempt to bring speciation events into some kind of general scheme, based primarily (...)

    A Particular Synthesis: Aleksandr Promptov and Speciation in Birds. [REVIEW]Nikolai Krementsov - 2007 - Journal of the History of Biology 40 (4):637 - 682.
    During the 1930s, Aleksandr Promptov—a student of the founder of Russian population genetics Sergei Chetverikov—developed an elaborate concept of speciation in birds. He conducted field investigations aimed at giving a naturalistic content to the theoretical formulations and laboratory models of evolutionary processes advanced within the framework of population genetics, placing particular emphasis on the evolutionary role of bird behavior. Yet, although highly synthetic in combining biogeographical, taxonomic, genetic, ecological, and behavioral studies, Promptov's speciation concept was ignored by the (...)

    The Myth of Bacterial Species and Speciation.Jeffrey G. Lawrence & Adam C. Retchless - 2010 - Biology and Philosophy 25 (4):569-588.
    The Tree of Life hypothesis frames the evolutionary process as a series of events whereby lineages diverge from one another, thus creating the diversity of life as descendent lineages modify properties from their ancestors. This hypothesis is under scrutiny due to the strong evidence for lateral gene transfer between distantly related bacterial taxa, thereby providing extant taxa with more than one parent. As a result, one argues, the Tree of Life becomes confounded as the original branching structure is gradually superseded (...)

    Towards a ‘Greater Degree of Integration’: The Society for the Study of Speciation, 1939–41.Joe Cain - 2000 - British Journal for the History of Science 33 (1):85-108.
    Intellectual and professional reforms in evolutionary studies between 1935 and 1950 included substantial expansion, diversification, and realignment of community infrastructure. Theodosius Dobzhansky, Julian Huxley and Alfred Emerson organized the Society for the Study of Speciation at the 1939 AAAS Columbus meeting as one response to concerns about ‘isolation’ and ‘lack of contact’ among speciation workers worried about ‘dispersed’ and ‘scattered’ resources in this newly robust ‘borderline’ domain. Simply constructed, the SSS sought neither the radical reorganization of specialities nor (...)

    Charles Darwin's Biological Species Concept and Theory of Geographic Speciation: The Transmutation Notebooks.Malcolm J. Kottler - 1978 - Annals of Science 35 (3):275-297.
    Summary The common view has been that Darwin regarded species as artificial and arbitrary constructions of taxonomists, not as distinct natural units. However, in his transmutation notebooks he clearly subscribed to the reality of species, on the basis of the criterion of non-interbreeding. A consequence of this biological species concept was his identification of the acquisition of reproductive isolation as the mark of the completion of speciation. He developed in the notebooks a theory of geographic speciation on the (...)

  13. Chicken, Eggs, and Speciation.Mohan Matthen - 2009 - Noûs 43 (1):94-115.
    Standard biological and philosophical treatments assume that dramatic genotypic or phenotypic change constitutes instantaneous speciation, and that barring such saltation, speciation is gradual evolutionary change in individual properties. Both propositions appear to be incongruent with standard theoretical perspectives on species themselves, since these perspectives are (a) non-pheneticist, and (b) tend to disregard intermediate cases. After reviewing certain key elements of such perspectives, it is proposed that species-membership is mediated by membership in a population. Species-membership depends, therefore, not on (...)

    Pierre Trémaux’s 1865 ideas on speciation have been unjustly derided following his acceptance by Marx and rejection by Engels, and almost nobody has read his ideas in a charitable light. Here we offer an interpretation based on translating the term sol as “habitat”, in order to show that Trémaux proposed a theory of allopatric speciation before Wagner and a punctuated equilibrium theory before Gould and Eldredge, and translate the relevant discussion from the French. We believe he may have (...)

    Speciation Post Synthesis: 1960–2000.Anya Plutynski - 2019 - Journal of the History of Biology 52 (4):569-596.
    Speciation—the origin of new species—has been one of the most active areas of research in evolutionary biology, both during, and since the Modern Synthesis. While the Modern Synthesis certainly shaped research on speciation in significant ways, providing a core framework, and set of categories and methods to work with, the history of work on speciation since the mid-twentieth century is a history of divergence and diversification. This piece traces this divergence, through both theoretical advances, and empirical insights (...)

  17. The Speciation of Modern Homo Sapiens.T. J. Crow (ed.) - 2004 - Oxford University Press UK.
    This is the first volume to address directly the question of the speciation of modern Homo sapiens. The subject raises profound questions about the nature of the species, our defining characteristic, and the brain changes and their genetic basis that make us distinct. The British Academy and the Academy of Medical Sciences have brought together experts from palaeontology, archaeology, linguistics, psychology, genetics and evolutionary theory to present evidence and theories at the cutting edge of our understanding of these issues.Palaeontological (...)

  18. Adaptive Speciation: The Role of Natural Selection in Mechanisms of Geographic and Non-Geographic Speciation.Jason M. Byron - 2005 - Studies in History and Philosophy of Biological and Biomedical Sciences 36 (2):303-326.
    Recent discussion of mechanism has suggested new approaches to several issues in the philosophy of science, including theory structure, causal explanation, and reductionism. Here, I apply what I take to be the fruits of the 'new mechanical philosophy' to an analysis of a contemporary debate in evolutionary biology about the role of natural selection in speciation. Traditional accounts of that debate focus on the geographic context of genetic divergence--namely, whether divergence in the absence of geographic isolation is possible (or (...)

  19. Recent Speciation Between the Baltimore Oriole and the Black-Backed Oriole.Jason M. Baker - unknown
    A recent phylogenetic survey of the New World orioles (genus Icterus; Omland et al. 1999) suggested that the Baltimore Oriole (I. galbula) and the Black-backed Oriole (I. abeillei) are sister taxa. That survey examined mitochondrial DNA (mtDNA) from a single representative of each species in the genus. Here, we examine mtDNA sequences from 15 Blackbacked and 20 Baltimore Orioles. The two species appear to be very recently diverged, with average sequence divergences for both cytochrome b (cyt b) and the control (...)

    Base Composition, Speciation, and Why the Mitochondrial Barcode Precisely Classifies.Donald R. Forsdyke - 2017 - Biological Theory 12 (3):157-168.
    While its mechanism and biological significance are unknown, the utility of a short mitochondrial DNA sequence as a “barcode” providing accurate species identification has revolutionized the classification of organisms. Since highest accuracy was achieved with recently diverged species, hopes were raised that barcodes would throw light on the speciation process. Indeed, a failure of a maternally donated, rapidly mutating, mitochondrial genome to coadapt its gene products with those of a paternally donated nuclear genome could result in developmental failure, thus (...)

    A Single-Locus Model of Speciation.Hans-Rolf Gregorius - 1992 - Acta Biotheoretica 40 (4):313-319.
    The crucial phase of speciation is argued to be the evolution of mating cross-incompatibility (prezygotic incompatibility) between the genotypes distinguishing the prospective species populations. Based on this idea, a single-locus model of speciation is presented, which is shown to be biologically plausible and may help to settle the controversy as to the biological significance of single-locus modes of speciation. The model involves three alleles, two of which characterize in homozygous state the prospective species populations and in heterozygous (...)

    Speciation Without Species: A Final Word.W. Ford Doolittle - 2019 - Philosophy, Theory, and Practice in Biology 11.
    This paper, like many before it, aims to solve the “species problem” by declaring it a non-problem. It borrows its title from an earlier article by Jeff Lawrence and its philosophical concepts from Marc Ereshefsky, John Dupré, Peter Godfrey-Smith, Ken Waters, and Jody Hey. The emphasis is on bacteria, but my pragmatic species anti-realist conclusion may be a general one.

    Genetic Engineering and the Speciation of Superions From Humans.Lucas Alexander Haley Commons-Miller, Michael Lamport Commons & Geoffrey David Commons - 2008 - World Futures 64 (5-7):436 – 443.
    Using ideas from evolution and postformal stages of hierarchical complexity, a hypothetical scenario, premised on genetic engineering advances, portrays the development of a new humanoid species, Superions. How would Superions impact and treat current humans? If the Superion scenario came to pass, it would be the ultimate genocidal terrorism of eliminating an entire species, Homo Sapiens. We speculate about defenses Homo Sapiens might mount. The tasks to relate two species (systems) constitutes a postformal, Metasystematic task. Developing a system of discourse (...)

Two ways in which egg dummy divergence can develop are described. Both mechanisms may have been operating, at the same time and in the same area, in different species, (...)
