Constructing Phylogenetic Trees using Multiple Sequence Alignment Ryan M. Potter Chair of the Supervisory Committee: Professor Isabelle Bichindaritz Computing and Software Systems Phylogenetics is the study of evolutionary relatedness amongst organisms. The genetic relationships between species can be represented using phylogenetic trees.

The first step in building a phylogenetic tree is to determine which group of taxa you wish to analyze; this set of taxa constitutes the ingroup. Depending on the scale of your study, the ingroup taxa might be very closely related to one another or not closely related at all. For example, a phylogenetic analysis of rabbits would include an

Building a phylogenetic tree Aim This activity shows how phylogenetic trees are con- structed using the morphological characteristics of organisms. It is an introduction to modern systematics that classify organisms according to their evolutionary relatedness. (c) David Gilbert 2008 Phylogenetic Trees 28 Tree building methods 1.

The use of the Unifrac metric helps to place communities in a phylogenetic context by first building a large phylogenetic tree, and then calculating the amount of the tree that is shared between two or more communities.

When we are building a phylogenetic tree from a dataset, our goal is to use shared derived traits in present-day species to infer the branching pattern of their evolutionary history. The trick, however, is that we can’t watch our species of interest evolving and see when new traits arose in each lineage.

Start by finding the closest relatives -the pair or pairs of organisms that have the fewest differences between them. In this example, beetles A and B have only one difference, so they are the closest relatives. Evolutionary trees, also known as phylogenetic trees, are visual representations of this branching pattern of evolution.
