Following on from the previous post Foundations of phylogenetics we’ll next explore how ties and matrix order can influence the Continue Reading …
Foundations of phylogenetics
For many years it was believed that patterns of evolution are tree-like and sometimes they are! We now know that Continue Reading …
Clustering to Reveal Hidden Traits: Using Neighbour-Joining Trees
Before we dive into the theory behind the Neighbour-Joining algorithm I wanted to do a simple conceptual exercise to highlight Continue Reading …
Decoding phylogenetic tree shapes
Phylogenetic trees can tell us about more than just the hierarchical order of our dataset. Taken together the position of Continue Reading …
What is a rooted tree?
Rooted trees A rooted tree is a tree diagram where the branches are ordered descending from a ‘root point’ The Continue Reading …
How to read a phylogenetic tree
A phylogenetic tree or phylogeny shows evolutionary descent from a common ancestor. The tree is built by aligning DNA sequences Continue Reading …
