1
He conjectures, for example, how saltation and orthogenesis might jointly explain phyletic sequences of limb rudimentation:
2
He then summarizes Mivart's structuralist alternative, describing first the claim for channeling, and then the argument for saltation.
3
That moral saltation is very necessary to political success at Leaplow, and quite probably in many other places.
4
Its characteristic dunes and ripples are the kind formed by sand particles taking short wind-borne hops, a process called saltation.
5
The existence of a few intermediary species shows that the full sequence proceeds by punctuational steps and not by full saltation.
6
He was no tumbler, and he had sent for a master of political saltation, who had just been with him practising.
7
Insufficient variation stalls natural selection; saltation deprives selection of a creative role but still calls upon Darwin's mechanism as a negative force.
8
Mivart faces these difficulties along the standard structuralist route, by calling upon the other concept so often twinned with claims for saltation: internally channeled change.
9
Microevolutionary saltation also scales as punctuation-sothe distinction between saltation and standard allopatry becomes irrelevant for punctuated equilibrium, since both yield the same favored result!
10
We can identify several pure channeling theorists-biologists ,whoextolled directional variation, but supported gradualism and rejected saltation (several orthogeneticists fall into this category).
11
Saltations could not be banished or denied, but only declared unimportant in evolution.
12
Saltation and channeling march in tandem throughout his argument, and the entirety builds a satisfying version of the full formalist critique.
13
"You will never be an adept in political saltation, John!"
