WebbHowever, phylogeny provides another perspective on biodiversity that allows an objective way to compare uniqueness and diversity of taxa. Although various specific measures of phylogenetic diversity have been proposed, most share a basic approach by which phylogenetic trees are used to evaluate species richness in concordant groups.

An outgroup is a species or group of species that is closely related to the ingroup, the various species being studied.The outgroup is a group that has diverged before the ingroup.

We will run a Maximum likelhood phylogenetic analysis. There are other models/methods such as Neighbor-Joining, Maximum parsimony, and Bayesian.

In biology, phylogenetics is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relatio… Webb7 nov. 2014 · Molecular phylogeny, first based on comparison of 18S rDNA sequences [34,35] and later protein-coding gene sequences [36,37], however, did not support this classification of protostomes, but instead suggested their division into two major groups, the Ecdysozoa (those exhibit moulting) and Lophotrochozoa (those having lophophores …
