    The theory of punctuated equilibrium has been proposed as a challenge to the modern synthesis of evolutionary theory. Two important issues are raised. The first is scientific: whether morphological change as observed in the paleontological record is essentially always associated with speciation events. This paper argues that there is at present no empirical support for this claim: the alleged evidence is based on a definitional fallacy. The second issue is epistemological: whether macroevolution is an autonomous field of study, independent from (...)

  3. Jason M. Baker, Recent Speciation Between the Baltimore Oriole and the Black-Backed Oriole.
    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 (...)

    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 Ônew mechanical philosophyÕ 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 (...)

    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 the creation (...)

    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 (...)

    Sexually active male haplochromine cichlid fishes possess pronounced yellow ovoid spots on the anal fm, which mimic eggs of the female and have therefore been called egg dummies (Wickler, 1962b).It is thought that divergence in egg dummy characteristics can considerably reduce gene flow and in this way may trigger off reproductive isolation. 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, (...)

    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 state their hybrids. (...)

    We defend a realistic attitude towards biological species. We argue that two species are not different species because they differ in intrinsic features, be they phenotypic or genomic, but because they are separated with regard to gene flow. There are no intrinsic species essences. However, there are relational ones. We argue that bearing a gene flow relation to conspecifics may serve as the essence of a species. Our view of the species as a Gene-Flow Community differs from Mayr’s definition of (...)

    Biomedical researchers claim there is significant biomedical information about humans which can be discovered only through experiments on intact animal systems (AMA p. 2). Although epidemiological studies, computer simulations, clinical investigation, and cell and tissue cultures have become important weapons in the biomedical scientists' arsenal, these are primarily "adjuncts to the use of animals in research" (Sigma Xi p. 76). Controlled laboratory experiments are the core of the scientific enterprise. Biomedical researchers claim these should be conducted on intact biological systems, (...)

    Claude Bernard, the father of scientific physiology, believed that if medicine was to become truly scientiifc, it would have to be based on rigorous and controlled animal experiments. Bernard instituted a paradigm which has shaped physiological practice for most of the twentieth century. ln this paper we examine how Bernards commitment to hypothetico-deductivism and determinism led to (a) his rejection of the theory of evolution; (b) his minima/ization of the role of clinical medicine and epidemiological studies; and (c) his conclusion (...)

    Richard Goldschmidt famously rejected the notion of atomic and corpuscular genes, arranged on the chromosome like beads-on-a-string. I provide an exegesis of Goldschmidt’s intuition by analyzing his repeated and extensive use of metaphorical language and analogies in his attempts to convey his notion of the nature of the genetic material and specifically the significance of chromosomal pattern. The paper concentrates on Goldschmidt’s use of metaphors in publications spanning 1940-1955. -/- .

    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 (...)

    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 intrinsic characteristics (...)

The main focus of Page’s book is thus when, how (...)

    Starting with Aristotle and moving on to Darwin, Marco Solinas outlines the basic steps from the birth, establishment and later rebirth of the traditional view of living beings, and its overturning by evolutionary revolution. The classic framework devised by Aristotle was still dominant in the 17th Century world of Galileo, Harvey and Ray, and remained hegemonic until the time of Lamarck and Cuvier in the 19th Century. Darwin's breakthrough thus takes on the dimensions of an abandonment of the traditional finalistic (...)

    The book aims to offer a contribution to the historiographical and conceptual reconfiguration of the evolutionary revolution in the light of the centuries-old tenets of the Aristotelian biological tradition. Darwin’s breakthrough constitutes a thorough overturning of the fixist, essentialist and teleological framework created by Aristotle, a framework still dominant in the 17th Century world of Harvey and Ray, as well as Galileo, and then hegemonic until Linnaeus and Cuvier. This change is exemplified in the morphological analysis of useless parts, such (...)

Wagner suggested that the isolation of a colony from its original source is a preliminary and necessary factor for speciation. Weismann accepted a secondary, facilitating role for isolation, but argued that natural and sexual selection are the primary driving forces of species transmutation, and are always necessary and often sufficient causes for its occurrence. The debate with Wagner, which occurred between (...)
