n. pl. phy·log·e·nies
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.

However, the position of the Arbutoideae as sister to remaining subfamilies of Ericaceae in this study contrasts with the phylogeny recovered in the study by Kron et al.(2002) that suggested the Monotropoideae occupy this position.
A phylogeny is an evolutionary tree reconstructed from its leaves (each of which represents a different species) by comparing DNA sequences or gene data with a plausible model of evolution.
They discuss a historical overview of concepts about phylogeny of microorganisms, multi-locus sequence analysis and bacterial species phylogeny estimation, the phyla of cultured and uncultured prokaryotes, applications of conserved indels for understanding microbial phylogeny, horizontal gene transfer and the formation of groups of microorganisms, endosymbiosis and the evolution of plastids, and other topics.
The goal of a unified phylogeny appears within reach.
The logic underlying the use of stereotyped behaviors for phylogeny estimation is the same as that underlying the use of morphological data: stereotyped behaviors are as species typical as morphology, and it has been shown that there is no significant difference between those two kinds of data in assessing phylogeny (de Queiroz & Wimberger 1993).
We present an analysis of this group of hamsters using retrotransposons as phylogenetic markers to further assess the modified phylogeny. Retrotransposons represent a group of transposable elements that integrate into new genomic locations via an RNA intermediate.
Molecular phylogeny of horsetails (Equisetum) including chloroplast atpB sequences.
It combines pattern-based analysis with comparative genomics and enables visualization of genes in the context of regulation, gene expression data, phylogeny, chromosomal neighborhoods and identification of natural gene fusions.
The phylogeny that was used includes grass species with diploid genomes of known DNA content and integrates results from a recent and comprehensive phylogenetic study based on macromorphology, anatomy, biochemistry, and the sequence of chloroplast and nuclear genes (Grass Phylogeny Working Group, 2001] with inferences from RNA structure and large-scale chromosomal rearrangements (Caetano-Anolles, 2005).
This project shows a new approach to orangutan phylogeny with focus on their long calls.
In addition to elucidating evolutionary relationships within the order, the phylogeny will serve as to tool for examination of epitope regions of the glycoprotein by identifying independent viruses for comparison.
