1. The evolutionary development and history of a species or trait of a species or of a higher taxonomic grouping of organisms: the phylogeny of Calvin cycle enzymes. Also called phylogenesis.
2. A model or diagram delineating such an evolutionary history: a molecular phylogeny of the annelids.
3. A similar model or diagram delineating the development of a cultural feature.

The application of this procedure to the phylogeny of the Caninae allowed a reduction in the level of incongruence among the morphological and mtDNA data sets, and led to a better tuning of their common phylogenetic signal.
This cycle occurred in all species observed, so this coordination of leg movements, used precisely in the context of prey capture, optimizes at the base of the phylogeny of the whole Orbiculariae group.
The method of using retrotransposons in the construction of a molecular phylogeny allows for a relatively simple and rapid, low-cost method of determining branching order for species.

In a recent study, a consortium of researchers described the evolutionary relationships of representative species within major grass subfamilies (Grass Phylogeny Working Group, 2001).
However, only a single reliable family-level phylogeny exists that includes deep-water fauna.
The usual chapter format is to lay out the molecule-based phylogeny and then to discuss the morphological, adaptive evolution in an ecological context.
The experimental phylogenies were analyzed as three replicated four-taxon phylogenies and together as a 12-taxon phylogeny. For each phylogeny, we compared nested models that differed in parameters associated with base composition, models of substitution, and among-site variation.
Few people bother to think about these matters, but the inquiring mind cannot ignore the incompatibilities implicit in considering the phylogeny of the soul.
He and Chen (2006) investigated biogeography and molecular phylogeny of the genus Schizothorax in China inferred from cytochrome b sequences, and their results also not congruent with the traditional subdivision of the genus Schizothorax.
This work has not previously been achievable due to the lack of a reliable kinorhynch phylogeny, And because the hard kinorhynch cuticle has hampered staining of muscular and nervous systems.
