read again-------I, correctly, used the word "abrupt" to
refer to a "speciation" faster than usual ----ie not in the
same very gradual process involving an aggregation of single base pair mutations that are not lethal and lead to very gradual, NON LETHAL, alterations in genotype and phenotype. -----but instead a WHOLE BUNCH OF MUTATIONS suddenly (as might happen on exposure to an unusual amount of radiation) which contrary to the usual scenario SURVIVES. Of course most "whole bunch of mutations" would be lethal-----but it could happen out of MANY such events that a few might survive and reproduce I just presented a possible theory for abrupt speciation-----try to cope. That Darwin did not consider such a possibility does not invalidate his ENTIRE theory. (sheeeeh----they're doing the same thing to Freud----trying to knock him
completely apart by screwing ((pardon the pun)) with
every detail of his stuff)

Nonsense.
You really don't understand the subject, do you.
1. According to Darwin...there had to be random mutations, and a competition among the variations.
There should have been myriad combinations of organisms...which would appear in the fossil record.
They don't.
a."Darwin’s theory of the development of living systems is based on gradual accumulation of micromutations, i.e. mutations that lead to slight changes in the phenotype of organisms. Only long-term accumulation of these minor changes, as a consequence of the consistent action of natural selection, can lead to major evolutionary changes in the structure of organisms.."
Macromutations evolution Frozen Evolution. Or that s not the way it is Mr. Darwin. A Farewell to Selfish Gene.
b. "By macro-mutation I mean a considerable hunk of DNA that contains more than one gene....All macro-mutations have drastic effects on development, most are lethal. "

2. But given huge amounts of time....couldn't the new organisms have come into existence? Sure. But Agassiz explained in an Atlantic Monthly article, "Evolution and the Permanence of Type,"
a) small scale variation never produced a difference in specie....and
b) large scale variation, produced either gradually or suddenly, inevitably resulted in sterility or death. "It is a matter of fact that extreme variations finally degenerate or become sterile; like monstrosities they die out." Agassiz, "Evolution and the Permanence of Type," p. 99.
Who says so?
3. "THE ABRUPTmanner in which whole groups of species suddenly appear in certain formations, has been urged by several palæontologists—for instance, by Agassiz, Pictet, and Sedgwick—as
a fatal objection to the belief in the transmutation of species. If numerous species, belonging to the same genera or families, have really started into life at once, the fact would be fatal to the theory of evolution through natural selection."
Darwin, "On The Origin of Species," p.302
