Etymologies

[From Greek phūletikos, of or for a tribesman, from phūletēs, tribesman, from phūlē, tribe; see bheuə- in Indo-European roots.]

Examples

  • This is both a phyletic tree and a nested hierarchy.

    A Disclaimer for Behe?

  • 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.

  • 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).

  • 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.

  • 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.

    Scientific Revolutions

  • 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).
