WebbUnderstanding a phylogeny is a lot like reading a family tree. The root of the tree represents the ancestral lineage, and the tips of the branches represent the descendants of that ancestor. As you move from the root to the tips, you are moving forward in time. When a lineage splits (speciation), it is represented as branching on a phylogeny.

When interpreting a phylogenetic tree, there is a tendency to presume that distance between taxa can be used to determine relatedness. However, branch tip proximity is positioned arbitrarily and can not be used to determine relatedness. " - The phylogenetic tree
