Here we differ. The fact that Lyell taught the immutablility of species, is not the point. I am not questioning Darwin's originality, but he was inspired by Lyell and Hutton.klypp wrote:Darwin's theory was not an offspring of the uniformitarian paradigm. Quite contrary.
Charles Darwin, for example, was well acquainted with Hutton’s ideas, which provided a framework for the eons required by the biological evolution he observed in the fossil record. English geologist Sir Charles Lyell, who was born the year Hutton died and whose influential book Principles of Geology won wide acceptance for the Theory of Uniformitarianism....

The fact remains that Darwin put his theory in the context of gradualism. He was under the influence of Hutton and Lyell, that is the uniformitarian paradigm. Darwin set his theory on the uniformitarian stage of slow and inexorable change. The uniformitarian geological paradigm came first and then Darwin put his new theory into that context, even though his own observations told him otherwise.
Again, this is my point...Darwin needed to fit his theory into the gradualist paradigm, because he subscribed to that paradigm. Nobody was stopping him from following the evidence of his own observations to their logical conclusion- that the geological record indicated periods of stability ending in a reworking of the Earth's surface and the sudden appearance of new and different species. Then as now, the alternative was a deity induced catastrophism. Secular catastrophism was, and so today is, not given serious consideration.klypp wrote:Darwin tried to get around the problem uniformitarians posed on him by suggesting the fossile records were imperfect.
The presumption of enormous time gaps in the geological record is an ad hoc addendum necessary to salvage a faulty theory.
The Velikovsky quote you cited (I assume from the V archive?) is not his theory of cataclysmic evolution, though it mentions the possibility of mass mutations. It deals with [url2=http://www.daviddarling.info/encycloped ... ermia.html]panspermia[/url2] and its' possibilities as applied to a Saturn event.
Copies of E in U are available in various libraries, it is worth the effort to find a copy. Evolution is treated extensively. Under the circumstances of planetary catastrophism the biosphere would be bombarded with a variety of radiations and electrical discharges. The protection of the atmosphere and magnetic field could be compromised exposing organisms on all levels to mutagenic forces giving rise to new species. Many of these would be poorly adapted and become extinct, but some would survive and continue to exist in the newly created environment.
If one accepts a key tenet of the EU, that electrical discharges have shaped the surface of the Earth, than one has to ask what is the effect of these events on the biosphere?Should an interplanetary discharge take place between the earth and another celestial body, such as a planet, a planetoid, a trail of meteorites, or a charged cloud of gases, with possibly billions of volts of potential difference and nuclear fission or fusion, the effect would be similar to that of an explosion of many hydrogen bombs with ensuing procreation of monstrosities and growth anomalies on a large scale.
What matters is that the principle that can cause the origin of species exists in nature. The irony lies in the circumstances that Darwin saw in catastrophism the chief adversary of his theory of the origin of species, being wed by the conviction that new species could evolve as a result of competition with accidental characteristics serving as weapons only if almost limitless time were at the disposal of that competition, with no catastrophes intervening.
