Evolutionary Epistemology in James' Pragmatism J
35 THE ORIGIN OF AN INQUIRY: EVOLUTIONARY EPISTEMOLOGY IN JAMES' PRAGMATISM J. Ellis Perry IV University of Massachusetts at Dartmouth "Much struck." That was Darwin's way of saying that something he observed fascinated him, arrested his attention, surprised or puzzled him. The words "much struck" riddle the pages of bothhis Voyage ofthe Beagle and his The Origin of Species, and their appearance should alert the reader that Darwin was saying something important. Most of the time, the reader caninfer that something Darwin had observed was at variance with what he had expected, and that his fai th in some alleged law or general principle hadbeen shaken, and this happened repeat edly throughout his five year sojourn on the H.M.S. Beagle. The "irritation" of his doubting the theretofore necessary truths of natu ral history was Darwin's stimulus to inquiry, to creative and thor oughly original abductions. "The influence of Darwinupon philosophy resides inhis ha ving conquered the phenomena of life for the principle of transi tion, and thereby freed the new logic for application to mind and morals and life" (Dewey p. 1). While it would be an odd fellow who would disagree with the claim of Dewey and others that the American pragmatist philosophers were to no small extent influenced by the Darwinian corpus,! few have been willing to make the case for Darwin's influence on the pragmatic philosophy of William James. Philip Wiener, in his well known work, reports that Thanks to Professor Perry's remarks in his definitive work on James, "the influence of Darwin was both early and profound, and its effects crop up in unex pected quarters." Perry is a senior at the University of Massachusetts at Dartmoltth. -

Stephens ii ABSTRACT This dissertation describes and presents a new type of interactive visualization for communicating about evolutionary biology, the dynamic evolutionary map. This web-based tool utilizes a novel map-based metaphor to visualize evolution, rather than the traditional “tree of life.” The dissertation begins with an analysis of the conceptual affordances of the traditional tree of life as the dominant metaphor for evolution. -
The Origin and Evolution of Model Organisms
REVIEWS THE ORIGIN AND EVOLUTION OF MODEL ORGANISMS S. Blair Hedges The phylogeny and timescale of life are becoming better understood as the analysis of genomic data from model organisms continues to grow. As a result, discoveries are being made about the early history of life and the origin and development of complex multicellular life. This emerging comparative framework and the emphasis on historical patterns is helping to bridge barriers among organism-based research communities. Model organisms represent only a small fraction of the these species are receiving an unusually large amount of biodiversity that exists on Earth, although the research attention from the research community and fall under that has resulted from their study forms the core of bio- the broad definition of “model organism”. logical knowledge.

This has such as single-nucleotide polymorphisms — that might changed in recent years with the availability of complete contribute to a disease phenotype. Similarly, knowing genome sequences from many model organisms, which that our closest relative is the chimpanzee is crucial for has greatly facilitated comparisons between the different identifying genetic changes in coding and regulatory species and increased interactions among organism- genomic regions that are unique to humans, and are based research communities. -
Honey Bee from Wikipedia, the Free Encyclopedia
Honey bee From Wikipedia, the free encyclopedia A honey bee (or honeybee) is any member of the genus Apis, primarily distinguished by the production and storage of honey and the Honey bees construction of perennial, colonial nests from wax. Currently, only seven Temporal range: Oligocene–Recent species of honey bee are recognized, with a total of 44 subspecies,[1] PreЄ Є O S D C P T J K Pg N though historically six to eleven species are recognized. The best known honey bee is the Western honey bee which has been domesticated for honey production and crop pollination. Honey bees represent only a small fraction of the roughly 20,000 known species of bees.[2] Some other types of related bees produce and store honey, including the stingless honey bees, but only members of the genus Apis are true honey bees. The study of bees, which includes the study of honey bees, is known as melittology.

Kyle Stanford ABSTRACT In earlier work I have argued that the most substantial threat to scientific realism arises from the problem of unconceived alternatives: the repeated failure of past scientists and scientific communities to conceive of alternatives to extant scientific theories, even when such alternatives were both (1) well confirmed by the evidence available at the time and (2) sufficiently scientifically serious as to be later embraced by actual scientific commu- nities.
