Druck auf Anfrage Neuware - Printed after ordering - While aware of the works of various evolutionists in their dotage (Galton, Wallace, Weismann), initially Bateson is likely to have overlooked Hugo de Vries' Intracellular Pangenesis. De Vries modified Darwin's hypothesis of 'pangenesis,' according the 'elements,' or 'pangens' that corresponded to individual characters, attributes that we now know to be those of genes. Darwin thought a character acquired during an individual's life time, could, by virtue of the transfer of the corresponding educated pangens (gemmules), be passed on to its children. However, experiments by Galton and Heape d- proved his belief that the pangens could move from normal tissue cells to - nadal cells. Like Weismann, Galton saw the potentially immortal germ-line (stored in the ovary or testis) as distinct from the soma (the mortal remainder of the body). Since gametes remained the same size from generation to g- eration, then each parent could on average only transmit half its elements to a child, the other half being lost. This meant that there might be competition between elements for representation in future generations. 'Ancestral' ch- acters that disappeared and later reappeared were due to 'latent' (hidden) elements. These were distinguished from the 'patent' (overt) elements that determined characters regularly seen in the offspring. Both elements were in the gametes as 'primary elements. ' The latent elements constituted a 're- due' that remained after separation of 'patent elements' from the primary elements. Galton downplayed the role of Darwin's natural selection.

Descrizione articolo

Riassunto

This is a biography-- written in the mode of Abraham Pais' biography of Einstein: "Subtle is the Lord." The Science and Life of Albert Einstein. There is one major difference. Whereas the science in Pais's text was relegated to esoteric small print segments, the authors highlight evolutionary biology as it is at a stage where it can be made intelligible to the educated reader. William Bateson brought the work of Mendel (and much more) to the attention of the English-speaking world. He commanded the biological sciences in the decades after Darwin's death in 1882. He gave twentieth century figures such as J. B. S. Haldane and C. D. Darlington a start in science, and was critical of the emergent Eugenics. We provide an understanding of Bateson as well as a reconciliation of diverging views (e.g. the hierarchical thinking of Gould and the genocentrism of George Williams and Richard Dawkins). Evolutionists may thus, at long last, present a unified front to their creationist opponents. About the authors: Alan G. Cock, Ph.D. was a lecturer in the Department of Biology at the University of Southampton, UKDonald R. Forsdyke, Ph.D. is a professor in the Department of Biochemistry at Queen's University in Kingston, Ontario.

Dalla quarta di copertina

William Bateson brought the work of Mendel (and much more) to the attention of the English-speaking world. He commanded the biological sciences in the decades after Darwin's death in 1882. To understand these years we must first understand Bateson. Through examination of the life of a major contributor to the turn-of-the-century revolution in biology, the authors of this volume reconcile the genocentrism of George Williams and Richard Dawkins with the hierarchical thinking of Richard Goldschmidt and Stephen Jay Gould. The anti-Darwinian arguments of Bateson are only now, a century later, gaining recognition. At last, Evolutionists can present a unified front to their creationist opponents.
