Phyletic

This is both a phyletic tree and a nested hierarchy. ❋ Unknown (2009)

Writing over a decade ago, UCLA biologists Laura Maley and Charles Marshall noted how genetic sequence comparisons carried out between different animal phyletic groups can lead to significantly different interpretations of evolutionary relationships depending on which species is chosen to represent each group (Ref 1). ❋ Unknown (2008)

Caling the ongoing “evolutionary” history of Intelligent Design cretinism a version of “punctuated equilibria” does a grave disservice to the mendacious proponents of ID, and especially, to invertebrate paleobiologists Niles Eldredge and Stephen Jay Gould, whose 1972 paper in which they offered punctuated equilibrium as an alternative to phyletic gradualism still remains an important classic in the scientific literature of evolutionary biology. ❋ Unknown (2010)

Remember that creationists were the original critics of phyletic gradualism although, alas, modern creationists tend to miss the fact phyletic gradualism has been dead for forty years, if it ever existed at all. ❋ Unknown (2010)

And here, too, those who resist Gould's attempt to sound so revolutionary as to be contrary to Darwin's phyletic gradualism note that it is only on a geological time scale that such developments as the Cambrian explosion appear to be episodic. ❋ Nickles, Thomas (2009)

Invertebrate stocks that colonized Ascension underwent a variety of evolutionary changes including phyletic evolution leading to endemic status, adaptation to subterranean life (Araneae, Pseudoscorpiones, Collembola, and Psocoptera), character release (phorid Diptera), and probably splitting of lineages (speciation) within the island (Isopoda, Collembola, and gryllid Orthoptera). ❋ Unknown (2008)

Meyer asserts that the Cambrian explosion represented an actual sudden origin of higher taxa; that these taxa such as phyla are “real” and not an artifact of human retrospective classification; and that morphological disparity coincides with phyletic categories. ❋ Unknown (2008)

Punctuated equilibrium is commonly contrasted against the theory of phyletic gradualism, which hypothesizes that most evolution occurs uniformly and by the steady and gradual transformation of whole lineages anagenesis. ❋ Unknown (2006)

If, for instance, a phyletic line evolves from the possession of two to the possession of three molars, the change does not occur by mutations giving one tenth, later one fifth, and one half of a new molar, but by one tenth, later one fifth, and then one half of the population having one new molar. ❋ Christopher O'Brien (2006)

Most of the “science” they cite concerns “controversies” of the third group in my list – controversies over how evolution happens; things like “did birds evolve from dinosaurs or from some other group of archosaurs?” or “did this trait evolve through selection or through neutral drift?” or “is phyletic gradualism more prevalent in the fossil record than punctuated equilibrium?” ❋ Unknown (2005)

Long stretches of time, competition, and ecological perturbation will add a measure of phyletic evolution. ❋ David Quammen (2004)

Over time, by way of phyletic evolution, it made them dainty. ❋ David Quammen (2004)

But Moritz Wagner failed to recognize that point; he missed phyletic evolution. ❋ David Quammen (2004)

Speciation demarcates new species, while phyletic evolution tends to increase the differences between species once they have been demarcated. ❋ David Quammen (2004)

Does phyletic evolution require geographical isolation? ❋ David Quammen (2004)
