... ; silently and insensibly working, whenever and wherever opportunity offers, at the improvement of each being in relation to its organic and inorganic conditions of life. We see nothing of these slow changes in progress, until the hand of time has marked the long lapses of ages... ' [1 ]. In Darwin's view, The extinction of species and of whole groups of species, which has played so conspicuous a part in the history of the organic world, almost inevitably follows on the principle of natural selection; for old forms will be supplanted by new and improved forms' [2 ]. In contrast to this notion of extinction through competition, as new, ...
22. Towards a New Evolutionary Synthesis [Books]
... the animals would be the size of a large elephant. With that, and a token nod to Gould, Eldredge and Stanley, he left the subject, as if all the apparently abrupt changes in the fossil record involved nothing more complicated than size. Although the book was intended to be a `general discussion of evolution', mass extinctions were never called by name, and the topic of extinctions almost totally ignored, more space being given to the subsequent adaptive radiations. Of course, evolution can proceed for millions of years without being influenced by a mass extinction, but when one occurs, from whatever cause, the whole course of evolution may be changed, as we ...
23. Glaciations, Biologic Crises and Supernovae [Journals] [Catastrophist Geology]
... ) Home | Issue Contents The Russian version of this paper has appeared in Bull. MOIP, sec. geologie, 1977/1 : 1-32. Glaciations, Biologic Crises and Supernovae L. J. Salop All-Union Geological Research Institute, Leningrad, USSR Summary and Introduction The organic evolution of our planet during the Phanerozoic is characterised by sudden mass extinctions of various groups acompanied or followed by the sudden proliferation of forms belonging to the same or to other groups. During the Precambrian and at the Precambrian-Cambrian bundary discontinuities are distinguished by the sudden expansion of many forms, not preceded by extinctions. Both types of crisis must be regarded as revolutions in the history of Life. An attempt is ...
24. Volcanoes, Earthquakes, Comets. Ch.9 Axis Shifted (Earth In Upheaval) [Velikovsky] [Velikovsky Earth in Upheaval]
... volcanic mountain in the world: Cotopaxi in Ecuador is over 19 000 feet high. The Andes reached their present height only in the age of modern man. Magma intruded into the rock and lifted it; in many places magma reached the surface, broke through vents, and built craters. Most of those volcanoes, however, are already extinct. Central America abounds in volcanoes, most of them extinct or dormant; the highest, Orizaba in Mexico, over 18 000 feet high, was active for the last time three centuries ago. In the United States few volcanoes are active, though many became extinct very recently, in the geological sense. Alaska, the Aleutian Islands ...
25. The Extinction of the Mammoth by Charles Ginenthal (Book Review). C&C Review 2002:1 [Journals] [SIS Review]
... From: SIS Chronology & Catastrophism Review 2002:1 (Jul 2002) Home | Issue Contents Book Review The Extinction of the Mammoth by Charles Ginenthal 1997 (Special edition of The Velikovskian, comprising nos. 2 & 3 of Vol. III) Jill Abery, J.B . Delair Charles Ginenthal takes us back to the exciting days of Velikovsky's Earth in Upheaval, with a plethora of new evidence which cuts the ground from under the feet of those who still doggedly hold the view that the demise of the large ice age' fauna across the high latitude regions of the world happened at the end of the Ice Age, around 10,000 years ago, due ...
26. The Age Of Man In America [Journals] [Velikovskian]
... From: The Velikovskian Vol 3 No 2&3 (1997) Home | Issue Contents The Age Of Man In America Charles Ginenthal "The disturbing reality is that for none of the thousands of well documented extinctions in the geologic past do we have a solid explanation of why the extinction occurred. We have many proposals in specific cases, of course: trilobites died out because of competition from newly evolved fish; dinosaurs were too big or too stupid; the antlers of Irish elk became too cumbersome. These are all plausible scenarios, but no matter how plausible, they cannot be shown to be true beyond reasonable doubt. Equally plausible alternative scenarios can be invented with ease ...
27. On Ecological Niches in Evolution [Journals] [SIS Workshop]
... Home | Issue Contents FORUM On Ecological Niches in Evolution Jill Abery comments: I quite understand David Salkeld's perplexity over Trevor Palmer's views. Trevor appears to be agreeing with me that natural selection during periods of stasis acts to conserve species and that periods of rapid evolutionary change occur only when the restraint of natural selection is lifted, as after catastrophic extinctions. How, then, can he say that it is unnecessary to postulate different evolutionary mechanisms during the different phases? I was forced to conclude that natural selection cannot be the force behind evolution and that, in fact, evolution does not occur during stasis. Trevor, however, is saying that evolution takes place all the time by ...
28. The SIS Evolution Debate Continued [Journals] [SIS Review]
... catastrophic periods of mutation'. His comments on the role of ecological niches were taken up by David Salkeld and formed the basis for a Forum' section in Workshop 1990:1 , pp. 14-15, together with Trevor's response. In turn, this brought a response from Jill, including her postulate of a different process' following mass extinctions, which was printed in another Forum' section (Workshop 1990:2 , pp. 24-25) together with Trevor's carefully weighted reply. The following four contributions continue that debate. The Creative Urge in Evolution?It seems to me that the basis for disagreement between Jill and Trevor is their differing philosophies, with Jill advocating full-blooded catastrophism ...
29. Fossils In Florida. Ch.10 Thirty-five Centuries Ago (Earth In Upheaval) [Velikovsky] [Velikovsky Earth in Upheaval]
... From "Earth in Upheaval" © 1955 by Immanuel Velikovsky | FULL TEXT NOT AVAILABLE Contents Fossils In Florida On the Atlantic coast of Florida, at Vero in the Indian River region, in 1915 and 1916, human remains were found in association with the bones of Ice Age (Pleistocene) animals, many of which either became extinct, like the sabre-toothed tiger, or have disappeared from the Americas, like the camel. The find caused immediate excitement among geologists and anthropologists. Beside the human bones pottery was found, as well as bone implements and worked stone. Ales Hrdlicka, of the Smithsonian Institution of Washington, D.C ., a renowned anthropologist (who ...
30. Prehistory and Earth Models [Books]
... . The Darwinian view of evolution sees all changes in organic form as adaptive changes, but the students of evolutionary change, the palaeontologists, have often been very hesitant to accept such a view. Many have voiced the opinion that in certain cases evolution appears to be non-adaptational, and have generally added that it is directional, maybe leading to extinction. There is a large and familiar literature supporting such views, some in an extreme form. It is however equally clear to any student of past or living forms that much evolution has been of an adaptive nature, and the plain fact seems to be that changes in organic form may be adaptational or not, and still persist. ...
