Definition: A phylogenetic tree or evolutionary tree is a branching diagram or "tree" showing the inferred evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical and/or genetic characteristics. The taxa joined together in the tree are implied to have descended from a common ancestor.

In a rooted phylogenetic tree, each node with descendants represents the inferred most recent common ancestor of the descendants, and the edge lengths in some trees may be interpreted as time estimates. Each node is called a taxonomic unit. Internal nodes are generally called hypothetical taxonomic units (HTUs) as they cannot be directly observed. Trees are useful in fields of biology such as bioinformatics, systematics and comparative phylogenetics. (Wikipedia)

User manual

1. Press `Build trees' to (re)build the UPGMA and Neighbour Joining trees.
2. Edit the fields of the distance matrix (only the lower ones are editable; the matrix is automatically made symmetric when you rebuild the trees).
3. Edit the `Sequence count' field and press `New input size' if you want to change the size of the distance matrix.
4. Press `Random data' to fill the matrix with random distance data.
5. For security reasons, the `Print tree' button does not work when the applet is run inside a browser.
