  • "Form follows function" trumps and "phenotype follows genotype"
  • "Long-branch attraction" - problem for molecular data, limited to the same four unordered alternatives per character
  • "The Contribution of Paleontology to Ornithology" - diversity of modern birds, fossils and avian tree of life
  • "Tree of Life" (TOL), premature - antithetical, to objective of the program
  • Chronology of recent analyses of phylogeny of modern Pelecaniformes - with critical analytical criteria
  • DNA hybridization and demise of molecular phenetics - Sibley & Ahlquist's (1990) quintessential phenetics of DNA-DNA hybridization
  • Early roots and applications of cladistics - in phenotypic contexts, as morphological characters
  • Higher-order phylogenetic studies - phenotypic variations, within and among related characters, rendering assessments of homology, problematic
  • Market-driven editorial filters - obstacles to publication of phenotypic phylogenetics of modern taxa
  • Progress and obstacles - in phylogenetics of modern birds
